The Panny XR25/45 were intersting to read about. I like the idea of slimmer and more efficient. Are there any more receivers of this type coming out from any of the manufacturers? The Panasonic receivers, and I believe there was another brand, were receivers which apparantly sounded surprisingly good. I have a Marantz SR6200 and high sound quality is important to me, so I'd be critical of the sound, but I'm curious if there is any trend in the digital amplifier direction. If its done right, I think its a good idea.
