Finally hooked up the ADA1500-5. I didn’t have time to re-run audyssey but I can tell it’s needed. The rears really came to life with the extra power but I didn’t notice as much with the front stage. I think it’s due to the speakers being set to small from the last audyssey calibration. The main thing I noticed was it’s a lot cleaner sounding and I enjoyed listening at lower volumes. I may end up trying some different banana plugs too. The ones I have are really snug in my avr but somewhat loose in the 1500. The posts seem to be shorter on the 1500 than the avr.
