LOL!!! I was writing while you were writing. First thing I checked, your speakers are hopelessly inefficient. Harbeth has the hutzpah to say they are easy to drive! Not at 86dB they're not! Doesn't matter the impedance! Now you know why you see all these guys in love with their speakers searching searching searching for the amp. Its not the amp. Its the speakers.
Also notice I didn't need any details. I worked this all out simply based on your first post.
