Are Martin Logans considered polite?

I've been going through this saga with some Magnepan 3.6Rs. I originally thought they were bright in my room, so decided to keep the Martin Logan Odysseys I bought at the same time and put the 3.6Rs up for sale. Since I've been trying to sell them, I've kept the Magnepans hooked up to demo them and tried some different speaker cable. With a different speaker cable and better termination, they sounded pretty damn nice, enough so that my wife even provided unsolicited feedback on a few occasions on how nice they sounded. So, I've been listening to them for the last few weeks. I've never heard piano sound as realistic in my room ever.

I literally just sold the speakers and they went out the door an hour ago (for those of you who have read my other posts, I ended up selling them at a steep discount to nice couple who can take the time and effort to get them repaired and still come out ahead). I hooked up my Martin Logans again. Now they sound a bit rolled off and muffled to me. After having lived years with a system that was on the bright side (with my PSBs), I naturally found the sound the Odysseys are producing attractive. Poor recordings are not so irritating, but this seems to come at a cost.

So, in the end, my question is are MLs generally considered rolled off/polite/laid back in comparison to other brands? Is it also a function of the narrow dispersion as well? This is a new room for me so have not yet started with room treatments and a lot of glass on one side, hard wood floors so i would expect this room to be brighter than many.

My problem with MLs is not at the top, it is at the bottom. ESL panels get very directional over 10 kHz. Unless you are right in front of them they are going to sound rolled off. They are quite capable of getting over 20 kHz. To fix this problem ML curves its panels and crosses to a sub. The inventor of the curved panel Roger Sanders will explain why this is a bad idea  http://sanderssoundsystems.com/ . Acoustat used angled flat panels which in the larger versions like the 3 s and 4 s did a credible job. Soundlabs carries that approach farther by using more angles in more partitions creating a speaker that will cover 45 degrees which is enough. Too much dispersion is just as bad as too little. What ESLs do not do is make the high end obvious. As good as Manepan's tweeter is, and I think it is the best magnetic tweeter available, it stands apart from the rest of the speaker. But you can be anywhere in the room and you will hear it.  
I find the speaker sounds its best if the high end is rolled of just a bit. 3 dB down at 20 kHz with an elbow at 3 kHz.

calanctus, Apogee Diva tweeters performed pretty much like Maggie tweeters but were even less durable. You can blow Maggie tweeters but Magnepan has a wonderful tweeter replacement program. If you can use a screw driver you are all set. Replacing the ribbon in the Diva was a royal PIA. Most people had to get the speaker back to Apogee to have it done. I had Divas for the better part of a decade. I know exactly why Apogee went under. One of the happiest days of my life was when I got my 2+2s back.

Nice 15 year-old zombie thread bump!  That might be a record.

 I've owned a pair of Martin Logan Vistas for about seven years, driving them with Parasound electronics. They are rather aggressive, and bright in the upper midrange, not what I would associate with a polite speaker. When I listen to rock, or full orchestra, I bring out my old Polk Lsi15's. They are just much easier, and more enjoyable, to listen to with some music.
