I was fortunate enough to use one for several months as my roomate had one given him when his father passed away. It had a really smooth sound but was no fun at all to move I used early Mac SS (C-26 MC-2505) which seemed like more than enough power. I also ran my Altec Valencias off the same setup in that room. When nobody was home I had several songs I'd listen to at elevated levels and it would literally make that old house feel like it was shaking.
