Exactly. You've answered your own question.
If you want better sound, get an external DAC.
That's what I did and it was a very good investment.

I'll grab something Pat Farrell posted about the sb
DAC:

"The build-in SqueezeBox DAC is not bad. Probably on the
order of those built into consumer "home theater" receivers.
I bought a Sony receiver with 5 channels and all sort of features
for $300 at Circuit City. I can't tell any difference
between either the SqueezeBox's $5 DAC or the Sony's $5 DAC"

I'd have to agree.

I've permanently ditched my Denon CD player and
all the hassle that goes along with managing individual
CDs. The DAC in that thing was probably on an order
of magnitude more expensive than the sb2 DAC, and
once I added my Benchmark DAC (used to have a
Big Ben Apogee) there's no comparison.

And that's still 1/3 the price of the Denon.

Speaking of which, I think the internal DAC is a Crystal 4334 DAC,
right?

If you are talking about the SB2, then no. You might want to reverify if Pat
said that about the SB1 or the SB2 DAC because they are very different
beasts.

In terms of DAC and DSP features/performance, Squeezebox1 is basically the same as SLIMP3, except with the addition of s/pdif output and pcm passthrough capability.

Squeezebox2 architecture has nothing in common with Squeezebox1 except for the internal OS and few other layers of software.

I had an older Carver Tube Reference CD player that cost me well over $1500 when I originally bought it. After only three days of listening to my SB2, I threw it in a box and its now collecting dust in my basement. I was absolutely shocked at how much better the SB2's DAC was.

Another factor in the DAC quality debate is the age of the DAC. Recent DACs have far surpased even (very) expensive older DACs in quality.

Technology keeps moving forward. Isn't it great?!
