Re: [SlimDevices: Audiophiles] Duet Sound
I did note a difference between the Duet and my SB2 when I first got it, the Duet somehow sounded more restrained. I seem to remember at the time that in fact there was a difference in output levels between the two, which would perhaps explain it. Now? I couldn't care less. I use the Duet into a MF-XDAC and the only thing I'd change is the DAC, the Duet is there to stay. -- CardinalFang CardinalFang's Profile: http://forums.slimdevices.com/member.php?userid=962 View this thread: http://forums.slimdevices.com/showthread.php?t=46079 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] BNC or RCA which should I use?
Tyler, I am not sure I would call SPDIF low frequency. The encoding technique chosen by S/P has an effective frequency of 5.6MHz - I'd call that RF. If you want to have sharp edges to the pulses then you are looking at needing harmonics way up the spectrum, the higher the better. On the basis of a failing memory of my EE days, I would guess that a decent 5.6MHz square wave would have significant spectral components up to 50MHz. Well worth trying to make a decent job of impedance matching the SPDIF link. -- Andy8421 Andy8421's Profile: http://forums.slimdevices.com/member.php?userid=16846 View this thread: http://forums.slimdevices.com/showthread.php?t=47046 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] BNC or RCA which should I use?
In my experience SPDIF can get flakey at over 5 metres of coax (rca). By flakey I mean it either works reliably with no clicks/pops or it doesn't. Not any kind of audible effect/degradation (like one might have with audio signals and long cables) Below that - certainly at the normal 0.5-1m cable lenght - I'm not totally convinced by the 75-ohm/BNC argument. Even if if correct, the BNC's need to be at both ends and everything needs to be proper 75 ohm components (not 50 ohm for example). I must admit, if I bought a TP I'd use its DAC. That way I'd get the benefit of NOT having SPDIF and certain jitter sources in the equation. -- 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+Stontronics PSU - Altmann JISCO/UPCI - TACT RCS 2.2X with Good Vibrations S/W - MF X-DAC V3/X-PSU/X-10 buffer (Audiocomm full mods)- Linn 5103 - Linn Aktiv 5.1 system (6x LK140's, ESPEK/TRIKAN/KATAN/SEIZMIK 10.5), Townsend Supertweeters, Kimber Chord cables Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=47046 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] BNC or RCA which should I use?
At the risk of inflaming opinion, I am happy to explain how I compared the systems. I would like to add that I was a EE 25 years ago and although time and technology have passed me by, I still have a healthy disregard for the 'I replaced the fuse in my mains plug with a nail and it tightened the bass up' sort of nonsense. Having said that, while I subscribe to the 'all digital source sound the same' argument, I did some work on digital to analogue systems for the BBC (we had digital even then) and sample jitter was a big deal. It is just as important for the DAC to have the correct sample output voltage as it is to have the sample at the right time. The highest precision DAC is rubbish if clocked with a jittery clock. SPDIF has an embbeded clock which can be subject to jitter on recovery, so in principle a jittery digital source 'could' sound worse than a source with less jitter (all other things being equal). So back to the test. Same DAC (the Krell - 24bit Burr-Brown I believe) same length 75 ohm coax, teminated with Neutrik RCA connectors (which are not 75ohm) going to Meridian CD player and to SB3 or Duet. Believe I had everything software configurable set the same for the two inputs on the Krell. To my ears, no question the Meridian path was better. May have been imagining it - who knows? But the soudstage was stable, clear and open with the Meridian, and didn't seem as good with the Duet / SB3. Was this due to jitter? - I have no idea. But back to my question if anyone has suffered through all my yesterdays. The transporter has two SPDIF outputs and one balanced EBU output. The two SPDIF outputs are different (according to the manual) the RCA output is capacitor coupled, the BNC is transformer coupled. Both have a source impedence of 75ohms. Why do they differ? and which is the best to use?
