I bought this amp a couple of months ago for the TBI Magellan sub in my office. Works very well, quiet, solid bass, good features, steep xover (24 db/octave). Uses tracking down converter power supply, like Carver, for high efficiency. Back fully enclosed.
I've put maybe 30 hours on it, but I have decided it is physically too large for the cabinet it is in, so I'm selling it for a smaller amp.
