Bel Canto CD-2 and Benchmark DAC1

The only audible difference between expensive and cheap transport is jitter (noise in time domain). Benchmark has such high jitter suppression (-100dB) that transport (or digital cable) won't make any difference. I use Benchmark with cheap DVD player (great tracking) or AirportExpress.
This is assuming that player is "bit transparent" (all 16-bits, no digital volume control etc.)

This sounds interesting cuz I heard a lot that DAC1 need really good digital source for better performance.

Capq - That's the main advantage of DAC1. It doesn't benefit from good transport or digital cables.

I've tried using the DAC1 on both my laptop (macbook pro via optical) and Marantz CD52 MK2 CDP and I have to say I can't agree with your opinion. Both of them are kinda low-end source but they sound huge different via DAC1. That's why I think to upgrade my CDP to a higher grade one.

As well as I saw a couple of fellows in Head-Fi use 3K+ CDP with their DAC1 or Apogee Mini-DAC. So I guess DAC1 can benefit from good transport.
