Greg - I would love to pick up some Khorns, but that is entirely out of the question. I don't have room corners to put them it! My listening room (living room) is about 15x22 or so with a sloping ceiling from 9 to 15 feet, lots of open doors to other rooms and no corners in sight. And I do like my Cornwalls. So, I'll replace the amp, buy some cables and perform some tweeks here and there. Loud to me is well above the level of converstion, I like to feel the bass. Thunderous dynamics. So with the large room, and the love of bass, would the tube still cut it. Yes I love quieter music also with warmth and air and a nice stage. How about bi-amping tube up top, ss on the bottom?
