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'm using an mhdt Constantine that I paid less than $400 for used and the sound is absolute top notch.
I am using the Berkeley Audio DAC with my Touch. I have the Touch going into the Esoteric G25U upsampler/clock - now, that's a nice upgrade. CIA power supply as well but thinking of the Boulder.
I have the Bolder power supply and the digital upgrade. The Power supply is about equal to the digital mod upgrade in terms of performance improvement.
lewinski,

why w4s dac2 if you can use the spdif output on the touch? wouldnt a w4s dc1 be enough?
