Magnepan announces the 20.7

Because of that review, a friend just got some MMG's for his HT. He's going to try them in the 2ch room and if they're successful, he'll order the 3.7's and sell his big Usher's.

If the 20.7 series is not bi-ampable and if your current 20.1's are bi-amped then it seems a little hard to compare. You can't compare bi-amped speakers with single amped speakers - on the other hand if your 20.1's are already bi-amped that's what you have to comare.
I bet no one will make such a comparison.

I do not bi amp my 20.1's. I do biwire them, however. I just am powering them with Cary 500MB amps and that seems a sufficient amount of power (1000 watts into 4 ohm load). Really enjoy the music--listen primarily to classical and jazz. Great soundstage. Have the extreme low end supported by a REL B1 but only at lowest half octave or so.

I hope Gifted Listener in Centreville gets them early on so I can hear both the 3.7 and 20.7. If the 20.7 can be bi-amped that would give them a huge advantage in my situation.

I still have my MGIIIAs which have been refurbished a couple time over the years ( My original Maggies were the 2Bs).

I now bi-amp then with 2 ARC D400s and a Marchand external XO along with a pair of velodyne subs. The D400 could run in bridged mode to take advantage of all the power and the guys at ARC said they could handle the current requirements, but I would still rather bi-amp if possible. Guess I have become a convert :-)

Bottom line is I think I have done all I can do to get the most from the old girls and the new "7 series" has got me drooling.

Word is you can't bi-amp them, they use a series crossover like the other .7's.
