All your amps are belong to my Haflers.

Okay, you guys make good points. The speaker-amp interaction is quite the deal. I've got a large number of amps, some of them bought on a whim to see if they could improve the sound of some of my speakers.

I was having a "b" of a time driving these JBL 4430s here in my office with a Carver (OK, don't start ), but a Soundcraftsmen A200 set them right.

Running some L7s with Soundcraftsmen A200s didn't work well, but Hafler PR2600s worked wonders with them.

Driving L250s with the Haflers just didn't quite get it, but a Fosgate Audionics 4125 was just the ticket.

Best thing for the L100s: vintage Kenwood KA-801 integrated amp. Best for the S2600s: Panasonic SA-XR10 digital amp. And so it goes.

I couldn't tell you how many amps I swapped in and out, sometimes with no discernible effect, then suddenly one just clicked. If I were smarter (or more educated) perhaps I could study schematics, impedance curves, etc. to predict these things, but I'm just a random sequence generator looking for the right combination.
