My Hsu VTF2 recently acquired a hum, despite my use of a cheater plug. I've swapped AC plugs, outlets, etc w/ no luck. The hum exists even w/ no receiver connection. The hum is loud and doesn't change w/ volume adjustment.

I'm guessing that the amp is toast and waiting to hear back from Hsu to see how much it costs to fix. Bear in mind that I bought this for $400 years ago so it's lived a good life.

All this recent sub talk had me looking at the Epiks. Has anyone actually listened to one? I was interested in SVS in the past but haven't seen many threads about them anymore.
