I use an Adcom GFA-545. You can get one in great condition on ebay.
I wait an hour for the amp to reach operating temperature and then the
sound is sweet. I get outstanding imaging. I recommend placing the
speakers 7-10 feet apart and 3 feet from the back wall, with no toe-in
(Depending on your room size). If you have a large room, give them
As much space as you can. You will be rewarded.
I also bi-wire with high-end Monster Cable (I am sure some people are
cringing

.
The music can get pretty loud without clipping. Someday I hope to drive
them with a Pass Labs X250.8 (mucho dinero). I prefer amps that
operate primarily in class A at the volumes I listen to music. Adcoms
are biased to operate in class A for the first 7 watts or so, if my memory
serves me correctly.
I’ve had these speakers since new in 1991. They still behave like they
are brand new. Treat them eith respect and they are there for the long haul.
I auditioned 32 brands of speakers and chose them (by a side margin).
I hope you enjoy your speakers.
