Well I finally got the Martin Logans I have been wanting for about 3 years. I ended up with the Motion 12, Motion 10 and Motion 8 center channel. I ended up with a Def Tec 1000 sub......got a killer deal. I am running it all with a Denon AVR 591. I am looking to upgrade my receiver, any thoughts? What is a good wattage to look for in a receiver? I really dont understand the Ohms thing. I have a general knowledge but the manuel say 4,6,or 8 ohms? How do I know what my receiver is putting out at? I am looing at the Denon AVR 1912 to replace my 591.
