DAC with AirTunes?

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.

Don't think you are ever going to be able to use your Nano for a remote... Its a fine device for what it is but... it doesn't have a digital out; it doesn't have the capacity to store any significant amount of non-lossy compressed music; it doesn't have bluetooth; and, even if it had bluetooth, bluetooth doesn't have the over the air capacity to do a digital audio PCM stream.

If you want an iPod interface, maybe the Squeezebox is for you. Gives you a remote and the Squeezebox interface is sort of like the control on the iPods. You can use the digital output of the squeezebox and run that into a standalone DAC for pretty good quality playback. Plus, with a bit of messing around, you can get the slimserver software that the squeezebox uses to "sync" with your iTunes music library, so you are only modding the library with one program....

Thanks for the input Edsilva,

Maybe you didn't read my post correctly. I realize the Nano does not have a direct digital out or bluetooth. I was referring to a *dock* that would have this. Similar to this dock:

Or this:

These would allow the iPod to be used as a remote. The latter needs a digital out but I suppose my Monster mini->optical digital cable may work. BTW, can the Monster cable connected directly to my iPod's heaphone jack allow me to use a digital connection?

You bring up a good point about bluetooth being able to handle it. Maybe there is(or will be) an 802.11g dock that can handle it better. As for the capacity, the 4GB should hold enough and if I need more it's just a quick stroll to my Mac to sync and change things. A bluetooth or 802.11g laptop with more capacity may be able to connect to this dock as well.

I'm going to research these docks more but for now I think I'll just stick to my AirPort Express w/AirTunes directly connected to my Arcam DACs via optical. If I need a display , I can pull out the laptop. That and my Keyspan remote will get me by till I find a better solution.
