czar2000 - I like it very much, but it bears little resemblance to a stock Beresford. The modder, K-Works (Igor Kuznetzov) replaced most of the electronic components (but not the DAC chip), added EMF sheeting, and mine has a huge 12 volt power supply (not sure of the type). I will put it this way: In an audio club shoot-out about 6 years ago, this DAC held its own against a $10K DAC from MSB, IIRC. In my system, it beat out a Wyred 4 Sound DAC 2 (stock version).
I may someday replace it, but mainly to get higher resolution capabilities, a USB input, and a built-in streamer to replace my Squeezebox Touch. But I am quite happy with the sound of this DAC, especially since upgrading the IC between the DAC and my preamp.
