Amp with best bass control

Thanks all! Speakers will likely be Raidho D3's.

Krell was my first reaction, especially the evo series, but I want to hear them along with Constellation, Vitus, Jeff Rowland and a few others. I've heard (and loved Soulution), but fear the 500 monos might not have the power I need. The 700 series is out of the question, maybe the 711 stereo which is coming. But I have a thing for monos!

Thanks again!

Well I would calmly vote for the Boulder 1060 as I know it well. This amp has enormous power reserves and delivers 600 watts @4ohms and has a damping factor of around 4000! The 1060 is also fast thanks to it's vast array of output transistors and distributed power supply. Damping factor is really the more relevent indicator of an amp's ability to control a speaker. It is also extremely well engineered and reliable. Depending on your budget, you can step up to the 2100 or even 3000 series. As you move up the Boulder line, you just get more of everything. Don't believe earlier hysterical comments about Krell. Boulder ran an a-b comparison at a Dealership in which a 1060 was thrown up against Krell Evolution 900 mono blocks and was much more dynamic and powerful sounding (especially in low bass). Paper specs are bs, and frankly Krell trade off their reputation. Boulder are the real deal. No other manufacturer has that level of engineering capacity or in-house content.

I would say check the latest reviews, Boulder amps have to many parts the signal goes thru, we all know that when that happens, you have a supar sound, the krells have been hailed world renowned as the best solid state for the price points it sales at, there are many amps better than boulder amps, Krell has a few models that are better!,Boulder is a good amp, defiantly not the last word in solid state!,, all this does depend on the flavor of sound one likes, and system synergy!I also will add, todays reviews mean nothing but a interest for an audition, these reviewers are payed good money to say what ever is good for the company!, likly, checking user reviews is the way to go, awards and pro reviews are nice for a product, however, let your ears be the judge!

Whoops, brain fart, I was thinking class D!

I've heard a lot about the EAD powermaster 2000 been an exceptional amp for home theatre and music. Excellent in the bass department.
