Re: [SlimDevices: Audiophiles] 24/192kHz capability for Transporter
Mr. Farrel, The better musical experience reported by some listeners (including professional critics) of higher resolution files in resolving systems IMHO is well documented. My concern, and I believe the concern of most audiophiles, is simply to have a more enjoyable musical listening experience; not to brag that their experience is better than yours or to engage in endless arguments about why a listener's subjective listening experience is fraudalent because it doesn't fit a particular view of the universe. The added musical enjoyment could be a placebo effect, but it is real. And to me, that is all that matters. -- cmarin cmarin's Profile: http://forums.slimdevices.com/member.php?userid=19133 View this thread: http://forums.slimdevices.com/showthread.php?t=69882 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

Doesn't iTunes and the Airport Express do it all? Actually the only question I posed was whether anyone knew if Logitech had plans to upgrade the Transporter to handle 24/192 files. I figured this was the appropriate forum to ask the question. Perhaps I made a mistake. For what it's worth, I find the Transporter to be an excellent server and use it to send its digital output to an outboard dac. My own model is a modwright transporter with a wonderful tube/analog output section. If it could handle 24/192 files, IMHO it would be an excellent alternative to other high resolution music server solutions that are being proposed. That is all. The argument, and one which I do not wish to engage in, is whether you believe that the ability of a serve to output 24/192 digital files, or anything higher than 24/96, is relevant or not to the music listening experience. You seem to suggest that there are clearly better forums for that. However, I did not raise that question. Someone else did. -- cmarin cmarin's Profile: http://forums.slimdevices.com/member.php?userid=19133 View this thread: http://forums.slimdevices.com/showthread.php?t=69882 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
[SlimDevices: Audiophiles] 24/192kHz capability for Transporter
I might have missed previous posts, but does any one know if Logitech intends to upgrade the ability of the Transporter to handle higher resolution (e.g., 24 bit/192kHz) files? I'm currently feeding my modwright transporter's digital signal to a playback designs DAC and would like to have the ability to play back files with resolutions higher than the Transporter's current 24bit/96kHz limit. Thanks. -- cmarin cmarin's Profile: http://forums.slimdevices.com/member.php?userid=19133 View this thread: http://forums.slimdevices.com/showthread.php?t=69882 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

Who is the manufacturer of the Touch? And does it provide 24/192kHz capability? -- cmarin cmarin's Profile: http://forums.slimdevices.com/member.php?userid=19133 View this thread: http://forums.slimdevices.com/showthread.php?t=69882 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] 24/192kHz capability for Transporter
I am familiar with the blue smoke music server that handles 24/192kHz and provides on the fly upsampling conversion as well; and of course you also have computer based severs. Too bad about the limitation on the transporter. I guess the economics are not sufficient to compell logitech to upgrade the Transporter. Sad because it's a great piece. -- cmarin cmarin's Profile: http://forums.slimdevices.com/member.php?userid=19133 View this thread: http://forums.slimdevices.com/showthread.php?t=69882 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

If you're interested in learning more about the quality of high resolution files please go to www.computeraudiophile.com. You will also find discussions/links on the relative quality of music files at different resolutions from 16/44.1kHz to 24/96 and higher, as well as how to setup players to optimally playback high res files. I would also direct you to the January 2009 issue of The Absolute Sound's articles on Reference Recordings' high res files and the review of the Berkeley Alpha dac. I believe that the superior quality of high resolution files in resolving systems is well documented. Below is a partial listing of sources for High Resolution files: Reference Recordings - offers 176.4/24 HRx WAV files (DVD-R) Reference Recordings - offers 176.4/24 HRx (DVD-R) Linn Records - offers 192/24 and 96/24 or 88.2/24 FLAC files (download) 2L - offers 192/24 FLAC files also some gratis 192/24 FLAC files Chesky Records - has 192/24 (DVD-R) Granted, the selection is still limited, but increasing. And IMHO high res files are the wave of the future. As to whether my system is resolving enough, you can be the judge: modwright transporter (digital out) playback designs MPS5 (dac - capable of 24/192kHz) dartzeel pre dartzeel amp magico v3 speakers. -- cmarin cmarin's Profile: http://forums.slimdevices.com/member.php?userid=19133 View this thread: http://forums.slimdevices.com/showthread.php?t=69882 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Transporter word-clock function

If it doesn't have a BNC output, you should contact Wadia and ask what they suggest to convert it to an electrical signal - that's the de facto standard. Sean, I'll contact Wadia.

Re: [SlimDevices: Audiophiles] Transporter word-clock function
seanadams;324445 Wrote: Yes, the file (WAV, FLAC, whatever) contains in its headers the information that _normally_ Transporter would use to select which of its internal oscillators to use. This information is also indicated (passed through, you might say) in the s/pdif channel status bits. When word clock is enabled, Transporter plays at the word clock input frequency no matter what the source file indicates that the sample rate is supposed to be. However, the information from the source file is still passed through untouched to the s/pdif channel status bits. So to rephrase (I think) your question, the problem is how does the Pace-Car know what sample rate to send the Transporter if it has yet to receive those s/pdif channel status bits? Well, it can't know until it gets them. So if you're playing along at 44.1 and all of a sudden some 96KHz content comes along, what will happen is that you'll have to switch your internal clock source as soon as you see 96KHz in the channel status. At that point there would be some brief drop-out of the signal while the PLL on Transporter's side resycns. I forget how fast that is but I think it's pretty quick - 10ms or something. Add to that perhaps some time for the s/pdif receiver to resync, which usually takes a bit longer. I don't know how noticeable it might be. I've never had an external clock source on-hand that could change its output word clock depending on the s/pdif information. What I do know is that Transporter will have no problem changing clock rates quickly - the way the PLL works inherently creates a clean transition. One thing that is fun to try, if you have a function generator, is to feed that directly into the word clock input and then turn the knob to hear what it does. Between about 20KHz and 100Khz it should have no problem. Above or below that range it will break in obvious ways. Sean, I recently heard my Transporter through a three box Wadia 9 system (1 control unit and 2 stand alone DACs). The sound was glorious. The Wadia has a glass fiber optic out to send the world clock signal to digital sources (Transport). My question is what modifications if any would be required on the Tranporter in order to use the Wadia's clock signal with the Transporter? Thanks.
