I bought this amp over a year and half ago to be used for monitors at a local church. Since installing, there has been no problems what so ever with it. It gets used 4 to 5 times a week, and although is never driven 'hard', it is well used.
Sounds good, and has adequate power for our needs, and 4 amp channels in one 1u box is amazing.
I had heard distant tales of problems, all I can say is it has worked flawlessly for us!
