Okay, it looks as if you are getting 192kHz output to the V-Link, but that the DAC can't lock onto it for some reason. The Touch can't influence the sample rate used by the V-Link since it uses asynchronous mode, so it seems that the clock in your DAC and the clock in the V-Link are too far apart for lock to occur reliably. Either that, or the cable is bad. You could verify this by using a computer to output 192kHz material to the V-Link 192 via USB2.0. If this doesn't work either (which is what I expect), then you have to figure out whether it is your DAC or your V-link that is offset in frequency in 192kHz mode. Without instrumentation, that's going to be difficult! dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=94512 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

All I can say is that in my living room with the particular combination of DAC, amp and speakers, I am finding a rather substantial improvement in imaging over not having the USB to SPDIF converter there. I am fully aware this shouldn't be happening. I suspect it may have something to do with galvanic isolation, but I didn't get the same apparent benefit from using Toslink as my connection. Irrational perhaps, but at least it is not blue dot, or CD-in-the-freezer territory (IMO)!

Re: [SlimDevices: Touch] Is the Touch more stable than the Duet?
I currently have a couple of Touches and a Receiver (the black box part of the Duet). I am also a Rhapsody subscriber. When Rhapsody itself is stable, which has been an issue in the past, I have no trouble with streaming. I can say that in recent months, Rhapsody has been reliable for me. The Touch has better WiFi connectivity, better sound quality, better network diagnostics and is more flexible in general. In my opinion, the Touch is a very well engineered device and is the best thing in the Squeeze line-up. The only issue to watch out for is high levels of WiFi interference, perhaps combined with a poor choice of fixed WiFi channel in one's wireless Router/AP. If you do get a Touch, consider checking your WiFi throughput using the graphical diagnostic provided and if it is solid over a 5 minute test, you can expect solid performance when using the device for real. dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=95505 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] USB HDD implementation flaky. Why?
I sympathise; you could expect better from an advertised function of the device. Sadly, you can't do much to mitigate the cold hard facts of an under-powered ARM processor doing dual duty as server and client. For a solution at work, without putting rogue devices on the network, my suggestion would be to buy a supported NAS device with sufficient compute power (e.g., NETGEAR ReadyNAS Ultra 2 Plus, or Synology DS212+). I know this will cost as much again as the Touch, but a direct ethernet connection between a decently powered NAS and a Touch is a very robust solution for playing your private music collection. You can install a DHCP server on the NAS if you wan't to avoid messing around with static IP addressing on the Touch (as long as you are sure you will keep the NAS on its own isolated network). The only down-side from my perspective is that you can't enjoy the benefits of cloud-based music services, but that option is already precluded if you're not allowed to put "rogue" devices on your company's internal LAN. dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=95280 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Re: [SlimDevices: Touch] Announce: Enhanced Digital Output app - USB Dac and 192k Digital Ouput
I upgraded from 0.1 to 0.2 via the up-date all menu option on the Touch. I was able to play via an AudioEngine D1 at 44.1, 88.2 and 96kHz, connected via an ac-powered hub to the Touch. I switched the DAC off via the front panel button, waited a few seconds powered it back on and verified that I could play music. A strange thing happened after leaving both Touch and DAC powered on for the duration of my day at work. After coming home I found I could not play music, even though both devices were still powered on from this morning's experiments. I further noted that the USB hub's green indicator light corresponding to the DAC was not lit. Power cycling the DAC didn't cause it to be recognized, either. Nor did completely unplugging the device from the hub and plugging it back in. Finally, I pressed the reset button on the Touch and waited for the reboot to complete. The green light on the hub corresponding to the DAC came back on, and music started playing. I am not sure whether the above experience means something has changed, or whether I was just unlucky this particular day. Anyway, thanks to Triode for this latest advance.

Re: [SlimDevices: Touch] Streaming 24bit Apple Lossless
In my experience, you will need to unplug the optical connection from the D1 and replug it in to have it recognize a sample rate change (e.g., from 44.1 to 88.2kHz). Firstly, you may want to verify if I am correct by starting to play an 88.2kHz or 96kHz file and while it is playing remove and re-insert the Toslink cable from the D1. If you find this works, you may wish to try Triode's new USB connectivity, aka Enhanced Digital Output with a USB connection via a hub to the AudioEngine D1. This way you would get perfect sample rate switching.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
I've had an AudioEngine D1 plugged into a USB2.0 hub and thence into the Touch, and it has been working very well for 44.1kHz ripped CDs and 24/96kHz FLAC downloads. Today I tried to play a low quality stream from a local radio station and got a "Pinky and Perky" impression. Nevertheless, the USB Audio info page reported 32kHz audio rate, which I think is correct. I have exactly the same issue with Klaus' TouchToolbox on the same stream. Oddly enough, when I go back to play a CD rip at 16/44.1kHz the DAC is no longer in asynchronous mode, and is stuck at at sample frequency slightly higher than 44.1kHz (i.e. 44,250Hz), with the expected audio clicks. Pressing reset on the SBT recovers the situation. This is 100% repeatable: playing the 32kHz internet radio station breaks asynchronous USB until reset is pressed. 32kHz is not a big deal for me normally, but it would be interesting to know if this is a peculiarity of the DAC I'm using or is also true for other DACs. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=93310 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Any thoughts on this? I have the Rega DAC too, BTW. Anything that has SPDIF as its output is going to suffer from the main design flaw of SPDIF: namely the need to recover the clock from the data. If you could go USB to I2S such that the clock is transmitted explicitly and separately from the data, you could get benefit from a USB D2D converter; otherwise, if the final link to the DAC is SPDIF, I would be very surprised if there was a (non-placebo) audible benefit. If you wanted to try this out anyway, just to test a null hypothesis, I would go with something like the M2 Tech Hi-Face EVO USB to SPDIF Converter. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=94218 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

@RadBadMark good that you could share that info. The only Arcam DAC that I know of that supports USB 2.0 audio is the D33. You seem to have something that is bus powered and yet accepts USB 2.0 audio @ 192kHz. The rDACs don't go above 96kHz USB audio 1.0. With which DAC did you conduct your tests?

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
I purchased an AudioEngine D1 for headphone listening and tried it via USB using kernel 3. Firstly, without a hub I heard clicks every 60 seconds or so. So I grabbed a USB2.0 powered hub I had lying around and placed that in circuit. Clicks were gone, and I could observe the adaptive momentary sample rate going above and below 44.1 depending on the buffer fullness. AudioEngine D1 is sounding good on its initial outing, via its RCA outputs into my main rig. Sound is rather pure and is notable for its image specificity, but otherwise does not draw attention to itself. Anyway, another victory for adaptive USB audio from the Touch. Thanks again to Triode. I hope he will keep his unofficial applets available for the future.

Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
So, I'm wondering if there is a recommendation for a USB DAC that is good enough in terms of power supply rejection, linearity, SNR and its own clock jitter to make the case for asynchronous USB connection over SPDIF and adaptive USB? It seems that everyone has adopted asynchronous USB even products that cost $150, but just doing the USB transfer mode right isn't enough to make a silk purse out of a sow's ear. Bottom line, is there a USB audio DAC product at or under US$ 1000 that is good enough to show the audible benefits of of being driven using asynchronous USB technology? -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=93310 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Async USB Dac Experiments - testers wanted...
Okay, I haven't been paying attention to what's been happening in Squeezebox land for a while, just listening to my music as often as I can via my SB Touch. So today, I come across this thread and on a whim and decide to try it out. I really don't have any nice USB DACs but I did try this with a REGA DAC, which has a "convenience" USB interface limited to 48kHz and 16 bits. Well this worked fine with kernel #3. Next I borrowed my son's NuForce Icon uDAC-2 and that worked straight away as well, at least for 44.1/16 audio. The ridiculous thing is that the NuForce is sounding better than the REGA when connected this way to my ears. Of course the real value of doing this comes Asynchronous USB. I am thinking NuForce does a special edition of their Icon uDAC-2 with Asynchronous USB for $250...I'm pretty tempted right now. I must say, triode, you've blazed a very useful trail here.

Re: [SlimDevices: Touch] Discrete Small PC - run server
I have run SBS on a Windows XP (Professional) box running headless with RDP for a couple of years, which was okay, but the need to keep virus scanners and security patches up to date was a pain. Also some virus scanners have been known to prevent MySQL from working properly, so you have to choose you security software carefully. I then moved on to a Buffalo NAS running SBS, which was fine for a while, but too slow to be much fun when rescanning the music library or waiting for the WebUI to update. In recent times I moved up to using the Vortexbox distro on a barebones Atom PC that needed only a 1TB HDD and a DVD-ROM drive to make a complete, and cost-effective solution. Of the three methods I've tried the Vortexbox distro has been the least hassle to maintain and the most fun to use. Its low power consumption also means I can leave it running 24x7. I don't have to worry about clashes with virus scanners, either, since Linux doesn't typically need such a thing. I prefer my current Vortexbox based solution to the other two possibilities I've tried, but your mileage may vary. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=87760 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

I have to respect the fact that you did the experiment and reported your experience. But I am surprised at this. Considering a 16 bit DAC and assuming I have my volume control set to place -90.31dBFS at 0dB SPL (the threshold of human hearing), I still have 90dB above that for the peaks of music. Assuming that the r.m.s. level of the music averaged over a track is -14dBFS (assumes we are not a victim of the loudness wars), that would be at 76dB SPL. That would be a comfortable listening level, not too loud but well above the SPL of normal conversational speech. I think you would have to listen at pretty high volume levels to hear the difference between a 24 bit DAC and a good 16-bit DAC. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=83976 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

There's no doubt that the correct bits get to the player's buffer no matter what transport mechanism is used to get them there. But at any point in the signal path during or after the conversion to analog, there can be an impact of power supply noise on the quality of the analog signal, as well as RF pick-up from the built-in WiFi transmitter on PCB traces on a few cm away from the WiFi antenna. Once RF pick-up at 2.4GHz does occur, it could easily be subject to parasitic rectification due to any semiconductors in the signal path that have a square-law term to their non-linearity. WiFi signals are not constant amplitude, unless you are using 802.11b, so some AM conversion to audio is possible from the very close proximity WiFi antenna. So, I would say there are plausible mechanisms within the laws of physics for sound to be different with WiFi turned on vs. off. Also, if the processor load changes the drain in the power supply, the ideality of the d.c. power supply may change in terms or residual ripple and digital hash, not withstanding that separate digital and analog power supply regulators are used to isolate them as much as possible. However, it should be noted that Stereophile's measurements did not indicate any real sign of trouble, when looking for low levels of noise and jitter. http://www.stereophile.com/content/logitech-squeezebox-touch-network-music-player-measurements JA states at one point: "Finally, the Squeezebox Touch's jitter performance remained unchanged, whether it was playing the 16-bit diagnostic Miller-Dunn tone via WiFi or stored on a USB-connected drive." Of course, he did not try ethernet, but the impact of WiFi being in use on these very sensitive measurements seems to be very well controlled indeed. Figure 9 is measured with WiFi being used as the data source. JA didn't specifically go looking for differences between the performance between the three interfaces (WiFi, ethernet and USB), but he notably didn't find anything adverse to publish about the performance using the (arguably) more vulnerable of these. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=85420 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

The plain facts are as follows: Our Red Book CDs are sampled at 44.1kHz. Whatever process was used to get to 44.1kHz sampling rate must have made an attempt to first satisfy Nyquist's sampling theorem by removing *all* spectral content above 22.05kHz. I don't care if that process was done digitally at very high sample rates or otherwise; the fact remains that a filter has to have been used that provides very good attenuation above 22kHz. The closer this filter is to a brick wall in shape the longer the impulse response tails (and pre-echo) will be. But there is very little latitude for making this filter 'relaxed' in the frequency domain because we want to have the passband extend to ~20kHz, and we want to be ~90dB down by 22.05kHz. This implies a high order filter, and an extended (some would argue unnatural) impulse response. There are still some choices to be made, but I think all of them are non-ideal, and yet at the same time indispensable. A NOS DAC attempts not to make the problem worse, but you must still live with the choice of decimation filter the mastering engineer chose to use. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=83976 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] A DAC for the SB
I used to have a Benchmark DAC1 in my system in my SB3 days, but after purchasing a Touch and doing some careful listening with the Touch direct and through the Benchmark, I found that if anything the DAC1 sounded a little forward and slightly grainy in the treble region, but otherwise very similar to the Touch. I know for sure that the Benchmark DAC1 measures better than the Touch, but since I could not hear it in my system with my ears, it made no sense to keep it. NOS DACs definitely break some rules, but in order to make a very specific trade: elimination of pre-and post-echo. (A similar motivation lies behind the use of apodizing filters in DACs and CD players, but without allowing excessive aliasing.) I don't think use of NOS techniques should be ruled out on principle, even though the presence of some inverted spectrum "music" added into the near-ultransonic region is -prima facie- the wrong thing to do. If you like it in your system, fine, but it's probably not for everyone. Frankly, I just don't think there is a thoroughly good way to reproduce music that has to be band-limited to 22kHz before sampling. That's one half of the damage, the remainder is done by an additional low-pass filter to suppress the aliases, when reconstructing a continuous waveform from the samples. Leaving out the alias suppression filtering clearly avoids further low pass filtering, but cannot remove what was done to make the recording. Everything we do here is some kind of compromise, which why some DACs and CD players offer multiple types of filter shape (e.g., sharp, smooth or minimum phase). None of them is the right answer; the only real solution being significantly faster sampling rates for digital recordings. I was reminded how much of a difference sampling rates make to the overall musical experience by downloading and listening to some of the free samples here: http://www.lessloss.com/high-resolution-audiophile-recordings-c-68.html Listening to the 24-bit/96kHz Bach recordings played though my SB Touch reminded me how wonderfully present, natural and non-fatiguing digital music -can- sound. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=83976 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

I think we have 6 because the SB radio has 6 physical buttons, so the functionality is already available.

Re: [SlimDevices: Touch] Setting presets on the Touch?
The attached ShortcutsMeta.lua.txt file needs to be renamed ShortcutsMeta.lua and placed in: /usr/share/jive/applets/Shortcuts/ (Perhaps you would want to back up the old one first.) Once the file has been installed, reboot the Touch and then activate the new default key bindings using the Settings > Advanced > Beta Features > Shortcuts > Restore Defaults menu item. The attached patch file shows the changes that were made: added 6 new lines and changed 6 lines. I am only activating 6 of the 9 numeric keys. The patch file is intended to document the changes made. +---+ |Filename: ShortcutsMeta.patch | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=10964| +---+ -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=78416 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

Although you mention Crashplan, you don't mention what kind of antivirus you're running. It is well known for certain anti-virus software to prevent MySQL from interacting with its temporary files, since this heuristically is a good match for malware behavior. However, this is most often observed during scanning, not so much as a random failure during playback.

I am running the Touch directly into my Creek 5350SE line-level inputs and enjoying the results. I used to run a SB Classic through a Benchmark DAC1 into the same amplifier. If I had wanted to I could have kept the Benchmark for use with the Touch, but careful listening did not motivate me to do so. Apparently, I willfully swapped Stereophile "class A" sound for "class D", and thereby joined the Great Unwashed. So be it: it sure sounds like music to me. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=82593 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] Touch Review in upcoming Stereophile issue
Kal, Excellent work on the review, which I enjoyed while listening to the "serviceable" analog outputs of the Touch. JA's measurements backed up your observations that a good outboard DAC would be of benefit, especially as regards noise floor for high-resolution material and low-frequency phase jitter. An asynchronous USB link to a high-quality DAC from Ayre should, and apparently did, offer an effective cure for both these limitations. It seems to me that having a USB audio connection is a much more interesting use for the USB port than providing for external storage for a somewhat crippled internal server (which I've never been tempted to use, anyway).

[SlimDevices: Touch] How to interpret limited availability of Touch in US?
The current unavailability of SB Touch via the better known online retail channels worries me. I don't mind a direct sales model if that is the official policy, but it seems odd that this one model from the SB line is only sold direct from Logitech. And if there are supply shortages to explain the lack of supply to retailers, why the oft-repeated but short-lived deep discounts to consumers via Logitech's site? Having built a great product, I would expect Logitech to make hay while the sun shines. I find the current behavior oddly self-defeating. Anyone know what's going on? -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=81036 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch

I saw those references, but since I had no direct experience of the Archos, I thought I should refrain from commenting on them. I did mention that the WD-TV does something very similar when you attach a USB drive full of media files. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=79212 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
Re: [SlimDevices: Touch] How large a music collection is "too large" for TinySC?
I am a very happy owner of a SB Touch, especially its sound quality, appearance and general usability. But I've never tested the TinySC part of its functionality; having an existing server running on a Buffalo Linkstation made that moot for me. I understand that prospective purchasers would like to know in advance what are the limitations of the built-in server. I also understand the bafflement of some that the music-scanning and database usage part of the functionality could cause so many problems. Comparison to an iPod has clearly generated more heat than light. But I get the point that having a low powered embedded system handle a hard drive full of music has been demonstrated on a massive scale by the iPOD. But an iPOD needs a serious computer running iTunes to perform the scanning part of work flow. A closer comparison would be the WD TV multimedia boxes that scan an attached USB disk full of multimedia files and make them available for browsing as a unified media library. If it were up to me, I'd define some hard limits within which the built-in TinySC is intended to function and have the UI inform the user when those limits were about to be exceeded. For example in the file discovery phase of the scan, I'd check if the limit was likely to be exceeded and warn the user if it was. What would irk me, if I were using TinySC, would be for the database/server functionality to use up so many CPU/memory resources that it effectively prevents the player from working. Admittedly any such limitation (e.g., a track count) would be a matter of judgement, but if chosen conservatively, it should be possible to guarantee the user a smooth experience. -- dsdreamer -- "Dreamer, easy in the chair that really fits you..." dsdreamer's Profile: http://forums.slimdevices.com/member.php?userid=12588 View this thread: http://forums.slimdevices.com/showthread.php?t=79212 ___ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
