Best DAC for Sonos


I was thinking of purchasing either a: PS Audio Link iii, Benchmark DAC1, Cambridge DACMagic or Musical Fedility V-DAC. Does anyone have thoughts on what might be the best to go between my Sonos and Krell preamp? Are there others that might be better?

Thanks in advance.

Beresford is cheap in cost and plays better than a lot of the DACs mentioned. It probably plays in the 800-900 dollar range but only costs 250.
My top pick at under (by a little) would be a W4S Dac1, sounds as good as the 2 but no volume control, and no high rate usb input, but if you're using it with a Sonos that won't matter. The new Rega Dac would also be a good choice.
Custodian.. I believe that Rick Cullen/ W4S can do a clock input mod on a Sonos http://www.wyred4sound.com/
While I am using a better DAC than this, I still have it. Very good sound:

PS Audio Digital Link III Cullen stage 4 modified. You can't go wrong with it for $1,300.00.
