New to computer audio and simple question....

Actually I am getting clicks and pops and my dac does not seem to like this mod.

This hack/tweak works wonderfully.

No, but there is a software hacking/tweak that might work in your situation:

Check it out,
Good luck,

i have used: apple airport express, apple tv with disk, and apple tv without a disk. you can't go wrong with the apple airport express for music only. pick 1 up from crqaigslist for $50, just make sure it is 'N' capable which is the latest 802.11 standard. if you want video, get the apple tv. you can pick up an older apple tv with a 40GB disk for $50 or so. this will allow you to stream videos, pictures, and music from your imac. they also come with a little white apple remote. the newer apple tv allows you to stream netflix plus all of the above. i also hacked my older apple tv's and got boxee, hulu, and 50 other stations from 'g' to 'x' rated. the only problem was that the video quality was terrible at the time, maybe the newer hacks are better. i eventually reinstalled the standard apple tv software.
the added benefits are that you can control the apple products seamlessly using an iphone/ipad/itouch.
to hook this up, the airport express uses the mini-toslink adapter to toslink cable (you can buy a adapter for a stock toslink cable from fry's for $3). with the apple tv's, you don't need the adapter.

Is an adaptor or box available to allow me to my USB dac with the Squeezebox?

Nope, Squeezebox has only coax and optical outs.

My Bel Canto only has a usb connection to the dac. Not sure if this means the squeezebox will work?

I feed my Denon receiver iTunes through my Apple TV, it wirelessly connects to the library on my laptop. You have to turn on Home Sharing, be logged into the Apple store, and have Bonjour running in the background (I'm a PC), so its a bit of a pain. Also I am recently having network issues, songs stopping right in the middle because the Apple TV loses contact with the laptop. Haven't hammered out all the bugs yet, but its great when it works! You might also consider an Airport Express...

I have been very happy with Logitech Squeezeboxes. Assuming your DAC has S/PDIF inputs (either coax or Toslink), it should work well for you. And they have both wired and wireless connections, so you can upgrade later to wired ethernet.

I'm with you there in being new to computer audio. As this is a secondary system another option you might consider is the Xantech BT6 bluetooth audio dock. Lists for around $130.00, got mine at Costco's for about half that. This would connect to a analog input in to your integrated amp. This assumes your computer is bluetooth capable. Can also be used with ipod touch and ipad as well. I have one for each of my three systems. Really cool and sound not too shabby.
