You might want to search out one of the discontinued EAD Powermaster amps. They made one that produced about 400 watts per channel into 8 ohms. I think it was eight channels. They come up used occasionally here and should be well within your price range. Very highly rated. Sorry I can't remember the exact model number, 8400 possibly, but it shouldn't be too difficult to track down. One of the best features of the EAD amps was something called dynamic steering. This allowed the amplifier to deliver much higher than rated output to adjacent channels if more power was needed there. Essentially this was a 3200 watt beast that could basically distribute that power to whatever channels needed it.
Need help in picking a 300w 7channel amp.
I have a 7.1 system with Definitive Technology speakers throughout (their best 7000 bipolars up front). Sounds great but I entertain a lot and at times need major volume. My Rotel 200wpc has failed me for the last time. I want to upgrade to something better and more powerful. The Lexicon ZX-7 has been mentioned. I want a 7 channel amp. Any suggestions would be appreciated. Price range is under $7500. Thanks,
