Nice amp dude. I've been using one just like it for a year or two maybe?
Wonderful piece of equipment. It'll play at very low levels very nicely, yet get loud enough to rock the walls for music and home theater.
The external bias adjustment is a nice feature too. The first time I ever adjusted bias was on this machine and it took me all of 15 minutes. Now that I know what I'm doing, I could do it in half the time.
Good luck on the sale. I can't imagine anybody wouldn't be very pleased with having this unit in their system.
By the way, it's a heavy little beast too. Like a tank.
