There is just no good way to describe the amazing difference in sound quality with the introduction of a Rotel amp in my system. I am using a RB-1070 borrowed from my dealer for evaluation which I'll return next week when my RMB-1075 arrives. Sound is soooo much clearer, when I turned the amp off it seemed everything was 'blurred', 'foggy', if you get the picture. It really made my speakers come alive. And keep in mind I'm using a Marantz 7200, which may not be top of the line but is in no way a bad receiver! A special thanks to Legairre, Larry B, George King and everybody else who pushed me into this move. Separates DO rule!
