Hello, I currently have a Harman Kardon AVR 325 and I'm considering replacing it with a Pioneer Elite VSX52TX; is this a good idea? I've read the specs on both many times, and all the reviews are great for both. Biggest differences appear to be the wattage ([email protected] 50watts x 7 / [email protected] 110watts x7) and the pioneer has an auto-calibration microphone which gets mixed reviews. My HK goes too loud for my apartment as it is so the wattage is less of a concern. Anyone here know both units enough to tell which may sound better? thanks for the help!
