I am looking for a new receiver for both HT 5.1 or 7.1 set up, as well as something that can do 2.1 for listening to music. My budget will probably be about $500.00, maybe slightly more. My front stage will be a Mid-Tweet-Mid set up for both left, right, and center channels that are all 4 ohm speakers. The sub is powered by a plate amp. Requirements for receiver: 1. Must be able to power speakers at 4ohms, therefore 4 ohm stable. 2. Must have a "tone" control knob, to change "treble" and "bass". I know some receivers dont have this feature anymore, but I would like it. 3. 5.1 and 2.1 set ups. 4. approx. $500 budget, and looking for something very clean with emphasis on sound quality. Thanks folks.
