What kind of amp do you like?

Widget, first world problems using a JC1 for woofers? Geez, I thought I was bad using a Bryston 4BSST2 for subs...

i just bought a First Watt J2 to power my 846A horns. currently building a ACA, may use that for horns and move the J2 to woofers... should work nicely.

I recently bought a Parasound A21+...

..The power is effortless with 160 watts a side on tap...

That model is 300 watts per channel @ 8ohms. I recently picked up an A 21(sans "+" that's 250 per channel) for running the woofers in a furure 3 way active project.

Classe A

Ones that sound good driving the speakers and don't get strained if I choose to cut loose and things get a little loud. The class isn't that important to me. As long as the loads they are working into is compatible to the overall amp design things should be fine. So pay attention to minimum impedances and phase in your speakers response plots as the combination can make life difficult for the amplifiers.

As far as technologies, topologies, and power output ranges go, I think there are great and not so great amplifiers of every type.

I've had many highly regarded amps, and I can tell you two that sounded best to me.

Sansui AU-7700 Integrated Amp Very clean and detailed, early to mid 1970's, about 50 W/ch*. Sansui knew what they were doing.

Alesis Matica 500 Power Amp 125 W/ch* , 80 V/usec I think this high a slew rate tributes to the sonic excellence of this one.

*Rated power outputs at 8 ohms nominal load impedance

Evaluations when listening with JBL 4410 and JBL 4412 monitors.

Class A solid state ..... the warmth of tubes without the distortion .

Historically high powered class AB power amps don’t work as well at low power levels. Lots of power transistors turning on/off with relatively low class A bias.

Bi amping with a transparent electronic crossover using a smaller high quality amplifier on the horn or midrange overcomes this limitation.

Wich kind of amp i like depends on wich speaker i want to use it with.

For example i had a Pioneer M-22, a small class A amp. Not so impressive with JBL 250ti...but with AR3a with its impedance drop this amp is great.

A Pioneer SX-1980 sounds fantastic with 250ti..but not with AR3a:s...but both are great amps in my opinion.
