DAC with AirTunes?


Can I improve my sound by adding an external DAC to my Airport Express/AirTunes->Arcam AVR300 connection or should I just stick with a direct digital connection to the AVR300? I'm using a Monster AirPort Express Stereo cable(toslink) now and thought about adding a lower priced used(Scott Nixon, Benchmark or Ack!) DAC into the mix. I'd go through the AVR300's analog inputs instead of a direct digital connection. I have some leftover .5 meter Kimber Silver Streak cables that I'd be using for my analog connection so all I'll need is the DAC.

Thanks for any input.

Asahitoro, there is lots of info on these topics in past threads. I'm not familiar with AVR300 (or any other HT processor), but if you buy an external DAC that is significantly better than the AVR300's DAC, sure, you definitely can improve your wireless music server performance. I doubt that switching from the AXpress to Squeezebox is going to get that kind of gain for you.
Thanks Jayboard.

I've been reading a lot of past posts and am still looking at my options. The AVR300 will let me use stero direct if I connect via analog but not digital so that's one reason I'd like an analog connection. The other reason is can an external DAC sound better for stereo than the AVR300's DACs, which while are good, may be more suited for 5.1? Is that true of most AV receivers? Is there a difference in DAC's for their intended main purpose?

As for the Squeezebox, I like the all-in-one solution if the DACs are that good that I won't need an external DAC. Also, I get a display and an option for a coax connection instead of optical.

Thanks again for the input.
I've been looking for a similar solution. I've read about Scott Nixon's TubeDAC+ which is a low-cost DAC with a tube output stage. There are good threads on A'gon about it. If anyone has any personal experience with it, I'd be interested to hear about it.
Asahitoro, I can't comment much further, because I haven't used the equipment you're talking about. Personally, I'd much rather use iTunes on a laptop on my couch than navigate with the Squeezebox display, but if you are thinking of a Squeezebox as an alternative to being in front of your desktop, then it certainly sounds attractive. But it's a $250 device whose main job is not DAC-ing. I wouldn't count on it to top or even match your Arcam, which I'm sure is a quality piece, let alone rival a dedicated, standalone DAC. I think you're hoping for a free lunch here!
Thanks again Jayboard.

After thinking this out more, I think you're right. I'm cutting corners with the Squeezebox. A laptop w/iTunes is a much better option than the little diplay. Maybe down the road I can find a bluetooth dock w/digital out that will allow me to use my iPod Nano as a remote. That combined with an external DAC would be the ticket. I can still go stereo direct that way and depending on the DAC, I can also take advantage of improving my Sony changer's two channel sound via the external DAC. I'll still keep another digital connection direct to the AVR300 for 5.1.
