It's really awesome preamp / dac . I use it in my P sistem - Dac Aiyima T8 and straight to my power amp Emotiva BasX A300 . Everything is beautiful, sound is excellent , but be aware that the output RCA is weak , like 1.9 V. So if you want more volume you really have to crank it up to allmost max volume from Dac . Except this thing, the preamp is really really good sounding and works like a charm
