As was recommended, sign up for notifications. I had DC offset and my subs as well as my mains amp. The transformers would hum when some lamps and kitchen lighting were on.I've had my FVX15 since March and am happy with it. However, I have an occasional hum, which I think is the dc offset issue as it still occurs with the RCA cable unplugged.
I noticed the recommendation for the Emotiva CMX-2, but it seems to be out of stock everywhere.
Anyone have another similar product to recommend? Any idea if the CMX-2 is coming back?
I also tried the Van Alstine Hum Dinger, but I preferred the CMX-2.
