Hello, I think after owning my setup for more than a year now, I am very much interested in the possibility of migrating to separates, as I hear the sound quality is much improved. Currently I have M&K 750thx speakers, with a Denon 1802 receiver. I also have a Denon 1600 dvd-a player. Problem is, the Denon 1802 only has 3 pre-amps spot available, so I thought starting off with a decent 3 channel amp would be a start. The M&K's are 4 ohm speakers across the front, so I suppose that would be a deciding factor too. Any advice would be appreciated. Thanks so much!
