Whoever said the marantz 7055 is no slouch was right. It's not even rated at 4ohm and plays my 3 new Martin logan LCR beautifully barely even getting a tiny bit warm. They play way louder at lower volumes than my def techs especially the 50xti center and my volume will probably never reach 70. Even if it did audyssey sets the 50xti center at -6db because it's a beast. You guys were right.
