However most of them do not sound as good as good quality 16Bits cd transport. The approach of connecting MAC or PC to high quality External DAC is
not an audiophile solution. The switching noise from MAC or PC power supply will find its way into your digital signal, which will cause jitter, noise, reduced soundstage, and harshness on your analog output.
The best approach is to use a completely dedicated music server. Designed for Audiophile applications to start with.
We have designed and built high quality external DAC (now selling direct from our web site), which deals with jitter. Our DAC improved computer generated output (SPDIF or USB-AUDIO) significantly, still the sound is better from High quality CD-Transport .
Alex, I would like to point a contradiction in what you say. Your “high quality external DAC” is not usable with “many music servers” as it look like your DAC is 16/44. I can’t imagine anybody build a music server to play juts 16Bit files. Particularly considering that you agree that “sound is better from High quality CD-Transport”.
The point about switching noise from MAC or PC power supply is well taken and well know. It very much makes sense to build a conventional PS, non-impulse PS fro music servers, though I did not credible comments that it does make any sonic improvement. Intellectually the switching suppers are bad, I would agree with it, even thought I have no idea how switching supply might cause jitter. Noise, yes. The residual switching pulses, yes? But jitter? I do not think so, explain if I am wrong.
Also, I would like to hear your opinion what methodologically appropriate was you might suggest to identify that my current music server does suffers from switching PS problems? I hear very same sound with no identifiable difference between direct feed of my preamp driven from tuner vs. the preamp driven via AD-DAW-DA path. If so, then how shell I learn about the tangible switching PS problems? BTW, sine I use “external” PS for my DAW I might ease to try it…The Cat
