McIntosh C2600 preamp and any McIntosh SSAmp up to as many watts as you can afford...!

The Don Sachs suggestion is a good one. Completely worth the wait. And built to order to a degree. So if you're concerned about system matching etc., be concerned no more.

I hope you are not going to fall for the watts per channel trap as the only way to measure an amps “power” and ability to drive a speaker or “load”.
I could steer you to some high power quality amps that only put our 25 watts per channel that matched with those speakers will make your ears bleed with a sweet sound.  Then you could by a class D amp that will put out 900 watts per that will sound like an old am car radio.
You need to look at an amps “power” like we do a car engine. I could give you a car that will go 0 to 100 in 4 seconds( horsepower) but could not pull a plow. Then I could give you a tractors that will pull a tree stump out of the ground (torque) but will do 0 to 60 in a day. Finding the right amp to make your speakers sing will involve the entire equation of quality clean watts per channel (horsepower), and power supply, voltage rails, heat control, power efficiency (torque). There are plenty to choose from so start auditioning with your speakers and enjoy the ride. But most of all don’t fall into the trap that has been set.

If referring to a trap being set by the Parasound A21+ that’s just garbage. That amp puts out real, usable watts. It will drive anything without a blink. If not referring to the A21+... never mind. I do agree however there are many great lower wattage amps that have ample push... I own one.
