Need some juice --- High power amps

I also run inefficent speakers 87 db carver's and 87 db magnepan's which are both 4 ohms. I have used many solid state amps and have found that Crest Audio amps are very powerful amps. I am running 2 sets of maggies in parallel (2.7 ohms) and they sound great, and the amp has never even gotten the slightest bit warm. No matter the speaker I have hooked to it the speaker gives up before the amp. Carver also makes some pretty stout amps that can be had at a firly reasonable price.
My personal pick would be the Crest Audio, but in the end the choice is yours. Enjoy your music.

Oops - guess there's not much involved to creating a link - didn't even know I was doing it - heheh. Now, where'd I put that drink...

One amp I've used that had an almost frightening amount of housepower is the Perreaux 350A. This thing pumps some current! Spec'd at 350 per ch at 8 ohms, it actually delivers ~500 per side; at 4 ohms it truly doubles-down. So that's potentially 1000 watts per ch, & with 87db speaks you do need it. I've cranked it & cranked this amp some more with never any signs of petering out, until I feared for the life of my speakers. The SPL's kept increasing until it felt like something's gonna come apart. Musical yes; however I can't say about the matchup with your speakers since they aren't mentioned: what speakers do you actually have?

Mcintosh mc501 - mono's, 500 watts per side of muscle and musicality. It came down to these and the CJ 350 for me. Haven't heard the others on your list. These boys woke my up thiels!

FWIW, for my 85db / 4 ohm / large room / blues & rock, I went with big tubes. If you prefer solid state, great, but ASL and Rogue and one or two others have got significant tube wattage at a fair price as an option if that is also of interest.
