I gave it only four stars for now because amazon is nagging me to do a review and I'm not done testing it yet. But it does seem to work fine, and the construction is high quality for the price. I run it from the stereo headphone/aux output of my yamaha pss-380 keyboard synthesizer into a dbx go-rack processor which feeds into a crown xls1002 class D power amp and two pair of andrew jones design pioneer speakers.....yeah.....it sounds awesome!  I'll probably come back later and give it five stars...lol.
