50/50 if it works
This is definitely a good unit from what I am told, unfortunately the one I got seems to be Dead on arrival, the sound is intermittent, it's not my cables or speakers either, they all work fine on a different amp. From the looks of it, I'm not sure if it was just bad, or if I somehow got a returned item?

Average bass sound quality
Bass regulation and frequency adjuatments are worst. I am trying to adjust it for punchy bass but i was getting more vibrations than punch.
