Thanks for the advice, and sorry it took me a bit to get back on.

My budget is around 3500 to 4000 for power (amp and pre-pro or receiver) and speakers for a 2 channel set up. This should also include cabling for those components, and a cd player.

In my absence, though, I have been doing some more listening. The short list now includes Jamo D450, Polk LSi-15, and Martin Logan Aeon. The Martin Logans would stretch the budget, though, and the luster of the Jamos was tarnished with certain rock CDs.

Any other suggestions on speakers?
