[SlimDevices: Audiophiles] Toslink cable test
I recently changed my SB1 setup to go through my BelCanto II DAC. This has one coax and one optical input, and as my Pioneer Elite DV-59Avi universal player uses the coax for Redbook output, I had to go optical. I took the opportunity to trial cables and was surprised at the difference they made. I started with a Radio Shack level $10 cable, went to an $80 Kimber Toslink, an $85 AQ Optilink 1 and then an AQ $200 Optilink 3. I found very discernible differences. I was mostly looking for detail and used two test cuts that have a lot of detail. I compared the cuts to the CD through the same DAC, using a Kimber Illuminations DV-60 coax cable and to each of the optical cables. The Radio Shack cable had a noticeable drop in detail compared to the CD/coax. The Kimber and Optilink 1 were similar -- a step up but not up to the level of the CD/coax combo. The Optilink 3 was indistinguishable from the CD/coax combo. I also tried the DV-60 with the SB and that was indistinguishable for me from either the Optilink3 or the CD/coax combo. I have to say that using a $200 cable to connect a $250 device took a bit of mental gymnastics for me. But considering it's part of a system with my server and DAC, that made sense. In the end, I'm getting good CD quality playback with all of the advantages of a media server, so spending the extra $120 or so isn't really that big a deal. -- mschlack mschlack's Profile: http://forums.slimdevices.com/member.php?userid=1159 View this thread: http://forums.slimdevices.com/showthread.php?t=29353 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Yeah indeed - mine was a lighthearted comment that perhaps there is nothing wrong with upsampling in principle, as long as it's done carefully. I am often not a fan of DBT: of course it is the right way to detect differences, but I find that the volume matching is very difficult (by ear, anyway).

Understood. That's why I was careful not to say 'better', but
'different'.
I'm not trying to provoke anybody. As an electrical engineer (but not
one who specializes in audio equipment, few are) I have always wondered
what any engineer can possibly do to a cable to make it transmit audio
frequency signals better, other than reducing the resistance and
increasing the capacitance. It is possible, I suppose, that there are
some phenomena that scientists have not figured out yet. So I am
perfectly willing to accept the possibility that super expensive cables
do sound different ('better' is subjective, 'different' is objective and
can be proven). Since you seem to believe in DBT tests, I was hoping you
can shed some light on this mystery.

By supported, do you mean it works or SlimDevices will give me official technical support for this. That could be a significant distinction. Since server-side transcoding is very flexible, I'd say that any format that can be understood by the server platform can work on the client. Since SlimServer runs on any platform you are likely to have, you could safely say the clients work for every format you are likely to consider. So I guess you should specify what your exact needs are. If you're asking What works?, well, everything works. I'm sure even MIDI files could be made to work. (Hey, that's a good idea...!) I'd follow the ripping guideline in the Wiki (http://wiki.slimdevices.com/index.cgi?BeginnersGuideToFileFormats) FLAC is a good choice for the uncertain. Even if you decide at a later time that you want to use a different format, because it's lossless, you can safely convert to a new format without losing any data (unless you choose to convert to a lossy format).

[SlimDevices: Audiophiles] Re: Toslink cable test
I can't understand how there can be differences in digital cables. As I understand it, in an optical cable, the S/PDIF reciever is looking for a change in state between bright and dim, not bright and dim themselves, but the transition. I suppose a sub-par cable would make this job difficult and it may miss a state change or two. Not too much though or you'd lose synch with the stream and get a dropout. As these signals form part of a PCM digital code, I fail to understand how missing the occasional transition could have a consistent, continuous audible effect. Any audible effect would have to be specifically written as part of the PCM code. You'd actually have to purposefully encode brightness or detail or specifically remove it from the signal at the originating S/PDIF transciever. Again, you may miss a transition or two, which I suppose could affect sound, but not too many or you lose the stream. How the cable affects jitter I'm not sure, but jitter is quite a small effect, and as bad as it is, I've never heard anyone accurately describe it. About the best I have ever read is that it affects airiness and spaciousness. Pretty difficult for a universal agreement given each person's hearing and equipment... Optical engineers in the telecommunications industry must be laughing at the audiophile community.

Hi sorry to hijack your thread but having a similar dilemma. Also using MusicInfoScr and don't seem to be able to get what I'm looking for... The issue seems to be that its not possible to set up the right hand display so that it can be used for Analog VU meters (which look really good on the Transporter) in screensaver mode and for extended text in now playing mode. The reasoning is that most of the time when listening I just want a subset of info (I can get this on the left display) with the VU eye candy ... but if I want the full lowdown on what I'm listening to I just press NowPlaying and get the full set of text info on both displays. I can do something like this if I have no visualiser on the right, or with the SpectrumAnalyser with text on top, but thats not what I want. Have I missed something? Am I asking for the impossible?

[SlimDevices: Audiophiles] Re: Trasporter display configuration - done much?
I was also thinking the Transporter screens aren't fully utilized to their advantage yet. There's twice as much real estate now, more VFD pixels than nearly any other device you can think of. One cosmetic thing: when both screens are in spectrum analyzer mode and the now playing text comes flying in from the right, this only takes place on the left-hand screen like on the SB3. This looks a little odd and truncated on the Transporter, it looks like it's coming in from the knob. ;-) It would look better if it flew in from the right screen, across it, then onto the left screen, perhaps after a slight pause as it goes through the knob panel. Also I was thinking of a pure data screensaver that would use both displays. Bars for buffer fullness and signal strength then text showing the bitrate and sample depth. Both these may be simple enough that I just might be able to muddle through and figure something out on my own, but if anyone is interested, go ahead. -- Mark Lanctot Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=29162 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I got the 7db high-gain antennas from Linksys for my WAP54G (I know its an old school AP but it works great) and then installed the 3.04 Hyperwap firmware to boost my TX power a little. I'm getting an 89% avg signal strength at the Transporter which is 2 rooms away with a microwave in between. I played 3 albums last night at 24/96 FLAC with only one stutter which I believe was caused by a heavy load on my server, not a wireless dropout.

Not all digital standards are created equal - S/PDIF is synchronous, meaning that the time at which the bits arrive is used to generate the clock which controls the DAC, and therefore timing variations affects the sound. Something like TCP/IP, on the other hand, is asynchronous - the bits arrive when they arrive, and if they don't arrive they get sent again. Not sure about HDMI, but from P Floding's comments I guess it's asynchronous. That said, in my own tests I was unable to distinguish between coax and toslink, so I'd be very skeptical about any differences between toslink cables.

First, let me agree that there's way too much emphasis on cables. I am every bit the skeptic. I did not do a blind fold test, but what I did do was observe the ability to hear low-level details that are right on the edge of resolution. I used A Case of You from Diana Krall's Live in Paris and If I Were Blue from Patricia Barber's Verse. The former has a lot of ambient stuff: people coughing, pedal noise, hall reverb. The latter has a nylon string guitar solo where Neal Alger takes a few breaths, moves around a bit on his chair, and of course, finger noise on the strings. I have used these cuts on many systems, and believe me, sometimes you can hear these things and sometimes you can't (even the ones you know to expect). I checked the volume with an SPL meter to make sure there were no level differences. While all cables showed some of this low level detail, there was a general correlation between price and detail. I re-listened when I thought I had heard something that I didn't hear on a cheaper cable, and verified every time. That says nothing about imaging, general tonal quality, etc. But I think the theory is that if you are dropping discreet low level events, you are probably also dropping transients, minor harmonics and other parts of the signal that make it life-like, contribute to imaging, and so on. At least, that was my theory. As to why, I don't know. I have read some articles on coax cables that talk about reflection. Digital signals travel as a pulse. Some people say that cables that don't strictly offer 75 ohm impedance can cause internal reflections (possibly other factors there too besides the impedance) that cause collisions between the pulses. That can lead to zeros becoming ones and vice versa, and if that happens a lot, some of the signal is degraded. Can that happen to an optical signal? Beyond my expertise. I have generally found optical to be inferior to digital, as have many people, but I don't why that would be either. I do know that if you talk to engineers who work in data communications, they can verify that optical cable quality is certainly an issue for high load or high distance, and that carriers, for example, spend more on cables that need it (is it single-mode vs. multi-mode fiber that's the difference?). That may or may not be relevant to carrying a single audio signal for a short distance. AQ's propaganda shows one being able to read a small e from a book through the Optilink 3, and not through the 1, but my eyes are way past being able to do that.

A good stable quiet supply reduces the jitter in digital circuits as well. Delay times and transition times of digital circuits are dependant on the supply voltage, so more tightly controlling the voltage can improve the amount of jitter. Do some web searching on over clocking the cpu in your PC, and you'll quickly see that tweeking the supply voltages are an integral part of the procedure. The clock and data are combined in the SPDIF signal, so any jitter in the clock on the digital sending side has the potential to influence the clock in the receiving DAC. Hope this make sense!

However, noise can be transmitted between components through the coaxial connection, so it is good to isolate the transport from the DAC, if possible, with a pulse transformer on the receiving end. -- ezkcdude DIY projects page: http://www.ezdiyaudio.com System: SB3-EZDAC-MIT Terminator 2 interconnects-Endler Audio 24-step Attenuators (RCA-direct)-Parasound Halo A23 125W/ch amplifier-Speltz anti-cables-DIY 2-ways + Dayton Titanic 10 subwoofer He's not hi-fi, he's my stereo. ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=29360 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
