Subject: RE: [slim] Modifying squeezebox clock
Having done a number of comparisons between various cd transports (dpa,
arcam) and the squeezebox into my dac using the same digital interconnect
I'd be interested to know peoples thoughts on what is causing the clear
differences heard if not jitter. Power supplies have been mentioned and to
an extent I would agree that they make a difference.
That would likely be just another source of jitter.
Another theory I've heard is that somehow interference / noise is being transferred from some transports to the dac and thus causing degradation to the sound.
I'd like to see some measurements of RFI, both for the wired and wireless versions of the SqueezeBox. I'll bet it's particularly high in the latter.
Anyone got any alternatives? The thing that doesn't really make sense is that flacs (pcm / wavs) have a worse digital output than mp3's.
I dunno. We don't know what the Squeezebox is doing with PCM streams, but there's no reason to think there should be a difference for the signal on the S/PDIF out. Something's definitely going on and it doesn't sound good.
I'm wondering if this is an internal rf noise issue as something will have
to be working harder to process more data than with mp3's - or perhaps not.
That's sounds plausible, though it shouldn't be from a CPU load standpoint, as the processor shouldn't have to work as hard in decoding the pcm stream. More likely it's in the network end of things.
