Greg T, I have both an XR-45 and XR-50 - was an early adopter with these units and have sold off most of the so-called high-end amps for anything but my subwoofer driver (I have Apogee Mini-Grands).Question: One might argue that the subwoofer crossover on the Pannys is a bit high at a minimum of 100HZ. What are the the crossover frequencies on the Kenwood and the JVC? I can't seem to find that info anywhere.
For anyone interested in the Panasonic units, it is important to note that if you are not using a subwoofer, you MUST select NO for the subwoofer and be sure to set the Front speakers for LARGE. This yields the BEST sound from these units. They will sound rather mediocre if not set up correctly.
Also, in case it's not been mentioned in previous threads, you can use four of the amps in stereo mode to bi-amp your speakers if they have the provisions to do so. You use the surround left and right channels along with the front left and right with the Receiver in SFC PARTY mode. In this mode you have the further option to adjust the volume of the surround channels relative to the front channels, and depending on which channels you've wired to you tweeters/midranges vs your woofers, you can taylor your sound a but. I find that biamping the Apogees with the Pannys improved their sound with these relatively inefficient speakers. I have heard the same results with B&W 802's. I do not know if either the Kenwood or the JVC provides the ability to do this. Greg, perhaps you can shed some light here as you own/have owned all three units.
