Classic: Can't believe that you found one. I have not seen one for sale for years. We "typed" about this amp quite some time ago (maybe at AA). It will run the original Advents well in a reasonably sized room (think you were talking about a basement). I ran across a website (don't have a clue as to what it was though) that talked about an upgrade for the amp (just a few parts replaced) that did wonders for the sound, though in it's day the 12 received very favorable reviews and if it is in good shape, should sound fine. I also used it with the Advent 300, but switched to a Phase Linear 400 when I went to stacked Advents. The phono section in the Advent smoked the one in the beefy HK 11 preamp of the time, but I don't know about the line inputs as I did not use them.
