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.

Sorry to reawaken this thread, but Ronrags, I was wondering how the Welborne power supply worked out for you?
Note that adding a better power supply (in my case the Pangea P100) to the DACMagic bumps it up to another level and sounds even better with the SBT. Amazing.
What about the Peachtree DACiT -- anyone tried it? It gets great reviews and some seem to prefer it over the DACMagic.
Thanks for the response Elem79.

So you hear a definite improvement with the addition of the peachtree DAC over the straight analogue out on the SB Touch? You think it's worth the investment?
