Looking for a DAC for the Squeezebox Touch


I'm new to digital since buying a Squeezebox Touch a few months ago. The Touch is connected to an external USB hard drive that contains cd ripped Flac files. I'm looking to buy a DAC for around $1k from the SB Touch and connect it to my Sim I-7. I'm considering the Moon 100D and the Wyred4sound Dac1 based on some reviews and comments in various forums. I might consider increasing my budget to possibly the 300D and Dac2 if it would make a substantial difference.

I got the Audio DG Digital Interface just for kicks and it made absolutely no difference to the sound over the Octave itself, at least to my ears. The manufacturer was correct, don't waist your money. My Digital Interface is going on the ebay. Bye Bye...
Earlxtr,

Please tell us more about the way you used the Audio DG: Was it SB Touch > coax > Audio DG > coax > Metrum?

Thanks!
Elem79, I have a question. Did you ever have an issue with clicks and pops after a while with the sbt and iDac? Sometimes I need to switch away from the input I'm using and then come back to eliminate the issue. Usually it comes back after a while.
