Best Amp with Magnepan 3.6's


Greetings - I currently own a pair of Magnepan 3.6's and am looking for any suggestions on an amp that would help me get the volume/sound I am missing.
My current systems is as follows:
Magnepan 3.6's
Rotel 1057 preamp
Rotel 1080 (200x2) amp
NAD 525BEE CD player
JL audio F110 sub
Transparent interconnects, and cables
As you can imagine I am not getting near the volume I would expect out of these 3.6's because of the limited power of my Rotel amp. I have researched different amplifiers and have it narrowed down to 2 (although I'm still open to suggestions). I've been looking into a Bryston 4B SST or a McIntosh MC402.
I would greatly appreciate any input or suggestions you may have. Thanks in advance.

For once I agree with Dave.

Krell is definitely "ear shattering".

Couldn't describe it any better.
Audiofeil, you really shouldn't offer so much valuable information and practical knowledge to the masses for free. Such insight and wit surely require some sort of compensation. You are such a giver...and that excessive amiability you exude! I just wonder what we would do without your benevolent nature and loving guidance. You are the beacon in the night, the soure of enlightenment by which we all gain encouragement and reasurance.
Oh, in case Audiofeil didn't mention it, please read the Soundstage review of the 400xi by Philip Beaudette in the Dec 2006 issue online. That will give you an even more fleshed out idea of what the 400xi has to offer. Live recordings can be quite revealing of a system, as Mr. Beaudette points out. Sometimes those Audiofeil approved components aren't as realistic sounding as they are talked up to be...of course I'm sure it isn't intentional.
'Test Drove' the Krell 400xi with 3.6s and found it not quiet satisfying, not to mention that in about 30" of moderately loud R+R, it was hot enough to cook on.
If you go Krell, make sure you are properly vented.
I thought you had 1.6's Magfan? The audio loom, as Art Dudley put's it, must be woven thoughtfully and with great care. No piece of equipment can overcome improper use and setup. From power cords to tweeter attenuaters to room properties....ya cant's just plops it in and expect to impress ya! You have to talk nice to it and take it to dinner first and then play some poorly recorded music loud enough to hear the inner distortion you missed before. By ear shattering, I meant to say that in a moderately sized room, one can play a full scale symphony or jazz band recording to beyond "live" levels and have no worries. Perhaps you are used to cold running eco friendly next generation amplification? Have fun:O)
