Re: [SlimDevices: Audiophiles] Any audiophiles got a SB Touch to beta test?

I guess it is a small time operation and sometimes when they mess up they are not owning up. But in my case they remedied it with a fast shipment. This was my second purchase from Welborne labs and my first was no problem at all. It wasn't actually me who made the comment about Welborne. I have no experience with them.

[SlimDevices: Audiophiles] Toslink vs Coax SB3 vs Reference [bits are bits (+ Jitter)]
See the test at the bottom. http://www.meridianunplugged.com/wiki/index.php?pagename=RMAATests The RMAA test is actaully less important than the work I did to actually diff the results. The Recorded files and the files I hand trimmed are included. I used a non 75ohm cable (because I was too lazy to dig one up) and for one test I used a CO2 converter to convert TosLink to Coax. Note there are 2 types of jitter. Peak to Peak and Clock Drift. The Meridian FIFO (or similar buffering in good DACs) will get rid of 100% of peak to peak jitter. A cable could change peak to peak jitter but it can't effect the clock drift jitter. So with a Meridian system (or a DAC with similar buffering) a digital cable should make ZERO difference. As well as TosLink vs Coax will make no difference. It also tells me SpeakerLink (a new Meridian connection) should make no difference since the DSP Speakers have FIFO dejitter as well and should eliminate cable differences. I was a little concerned the DTS Test was not 100% reliable, in that DTS does handle some errors. I had in the past recorded my own test wave forms and compared them bit for bit using a wave form editor. But this test is much more extensive and verifies it's not that hard to transmit every bit over SPDIF. All that is left with a Good DAC is effects of clock drift. -- mswlogo XP Cat5 Transporter/DuetController SPDIF Meridian G68 DSP6000, DSP5500HC, DSP5000 XP Cat5 SB3 SPDIF Meridian DSP5000 XP Cat5 DuetReceiver SPDIF Meridian G91 DSP5000 'My Transporter Setup' (http://forums.slimdevices.com/showpost.php?p=350741postcount=45) 'Hitch Hikers Guide to Meridian' (http://www.meridianunplugged.com) mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=79245 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Touch vs. Transporter digital output (again)
If you are recording and diffing s/pdif you will never see jitter. Jitter will only manifest post-DAC (assuming decent, working equipment - which you do have!). For jitter to manifest pre-DAC it would have to be so severe as to change the bitstream - which we all know it doesn't in the SB2/3/TP/Touch devices. All the evidence available points to the conclusion that the Touch and TP are pretty much perfect deliverers of s/pdif to a DAC... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...

SB3 is a perfect SPDIF deliverer too (both toslink and SPDIF). CO2 converts perfectly and TASCAM records perfectly. All that is left is jitter. And if your DAC buffers/reclocks that gets rid of all peak to peak jitter. So people must have really bad DACs if they can hear differences between toslink vs coax and this cable or that. -- mswlogo XP Cat5 Transporter/DuetController SPDIF Meridian G68 DSP6000, DSP5500HC, DSP5000 XP Cat5 SB3 SPDIF Meridian DSP5000 XP Cat5 DuetReceiver SPDIF Meridian G91 DSP5000 'My Transporter Setup' (http://forums.slimdevices.com/showpost.php?p=350741postcount=45) 'Hitch Hikers Guide to Meridian' (http://www.meridianunplugged.com) mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=78441 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
