There is a mapletree 2 se selling in audiocircle. U may be interested.

For the record I too own a 'd' ICE amp....

Be careful with 'd' amps. The Krell sure cooks, doesn't it? Maybe better ventilation? I tested 3.6s with the xi400 integrated and it sure got warm, and I didn't even try to abuse it. In my less than perfect space for amp, I'd kill it in a week.

Anyway, back to 'd' amps. The ICE modules are NOT whatever power FTC rating. No 1 hour at 1/3 power preconditioning and STRICT time limits at full power. The ASP module used in the kilowatt amps is ONLY 30 seconds at full power. My 500 watter is 60 seconds. Figure the efficiency at 100% power is about 83%, plug to speaker. That is a lot of power ALL going to heat. Go to the B&O website and look at some photos. Not much heatsink in any of those modules.
That doesn't mean they don't work in to REAL loads with MUSIC. Especially since music will only consume a fraction of an amps power with the rest being dynamics...at which the 'd' amps excel.
The take away here is to take the power ratings with a grain of salt.

You may like the panels flipped around. I spend a lot of time.....maybe 15 or 20 minutes per session tuning my speakers. When I got 'em where I wanted, I carefully documented and MEASURED the location. I used the wooded side stiles as marks and carefully drew my room in Google Sketchup and place the speakers.....A little trig and I know where the speakers 'cross' and the angle at which they are toed in.

You have a nice space. The ONLY red flag is the length being about 4x the height, but this is made better by the characteristics of panel/dipoles.

If I had really.....reallly deep pockets, I check out a Pass INT-150 and make whatever accomodations necessary if it sounded right. Maybe end up sleeping in the garage.....and eating rice and beans for a couple years.

Rockguitardude has it right
Try the 1.5 ohm or Evan higher resistors which Magnepan can provide
Try tilt back and play with toe in tweets on inside
Let them run in for at least 100 plus hours at low volume
Plug all AC gear into the wall not a cheese box computer strip

FYI, I lived with Maggies for many many years. About a dozen different amps; ss and tube. Used the Maggies in stock form and heavily modifed to their limits. Having said all that I am inclined to agree with Madactexas; the amp is probably the issue. However, everyone (specially you; obviously) has left out a key part of the equation: WHAT WERE THE SPEAKERS THAT YOU USED PRIOR TO THE MAGGIES, THAT (PRESUMABLY) WERE NOT TOO BRIGHT FOR YOU? Answer that question, and the advice will have some significance, instead of everyone stabbing in the dark. "Brightness" is a difficult thing to describe to someone else. I have often heard equipment described as "bright" when I would describe it as thin or harsh; and definitely not "bright". Very different things. Having said all that, I have a strong suspicion that if you stick with these speakers (I would), you will ultimately find that a decent tube amp is what will make you happy.

GREAT question! What WERE the last set of speakers!? I Hadn't thought of that!

Have you flipped 'em around yet? That tamed mine. And Yes, I'm a magnepan veteran. Close to 30 years now, but only a few amps. I've never been an equipment swapper and simply don't have the deep pockets it would take to do extensive experiments.

I'd like to hear what Frogman thinks 'modded to limits' means.

If you've been around panels a long time, you know they swapped sides sometime in the '90s....this to me, made 'em brighter sounding.
