Thanks again George. As I get more in to this hobby, seems I'll need to do some reading on classes of amplifiers and speaker pairing. There's a lot to learn. I have a Unit Atom and when the firmware went awry with my 7900, I hooked up the Aerials to the Atom (40 watt amp) so I could listen to music. It sounded a lot better than expected. And conversely, when I hooked them up to the 275 they sounded very thin and anemic. Your point is well taken.
Best regards,
Uncle BB
