Sorry for the stupid question.

So the Outlaw B-Stocks are fully quality checked and tested? I just got burned by a b-stock offering from another amp company. They told me it was fully checked and just a return but when I powered it up after connecting it to my speakers there was a very loud hum from the left channel only. I did all the ground loop tests and found the problem to be with the amp.

Thx in advance. JD
