View Full Version : Squeezebox analogue and digital-out soundqualitydifferences?

Sorry, just to reiterate on my previous post:

I have indeed done critical (headphone) listening to MP3s coming out
of:

A) Squeezebox / SliMP3 analogue out,
B) Squeezebox digital out through ADCOM GDA600 dac,
C) Nakamichi CD player through ADCOM dac,
D) Audiotron (shudder!) digital out through ADCOM dac

To my ears, there's no comparison between the analogue outputs and the
digital outputs through the ADCOM dac -- cleaner, smoother, less
coloration throughout the range. Significantly, I also found it
impossible to tell the difference between the digital outputs of the
Squeezebox and the Audiotron (when the volume matrix is bypassed on the
former).

The difference between the Nakamichi CD player and the Squeezebox's
digital out reflect normal MP3 encodiing artifacts -- in my case, lame
--alt-preset studio (3.92, which is 256kbps cbr). Very listenable.
