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.

The manual on the W4S says it takes 100-200 hours. You can hear some improvements after the 100 hours.
Ronrags, the Wellborne helped knock some of the digititis out of my setup, but it wasn't until I added the Burson that I was satisfied. SB internet radio was particularly improved by the modifications. The SBT is essentially my only source for my secondary system; I only use my CDP for CD's not yet added to my HD.
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.
