Berkeley audio alpha 2 dac vs. w4s dac 2 dsdse

My wyred 4 sound Dac recently went down ( something electrical) and while I am waiting for it to be fixed my dealer loaned me the Berkeley audio alpha 2 dac. Wow was blown away hearing new sounds. Had really liked my w4s Dac. It had been a few weeks since I heard good sound out of my Wilson sasha 1s.. With the new dac I staid up till 3am listening to music.
Any other opinions on these two dac?
