Maggie owners (past, present, future) what do (did) you love and or dislike about them?

I'm a present owner of a "past" mag- the MG III (refurbished). I purposely chose them as opposed to their immediate.successive models due to musicality and coherence. I cannot comment on the most recent models. 

You will generally need high current amp. My speakers need to be played fairly loud to get them to their potential. Close to concert level is impressive but the amp is critical. You need to get the membrane and back wave up to speed. They don't sound that great when played soft but that's not why you would get them in the first place.

To me, they excel in live complex large thick music. 

Depending on your music and taste, you may want bass reinforcement.

I second or third the favorable comments re John/ Peter Gunn/ Magnestand. Several years ago I communicated with John re diy mods. Although I have yet to implement many of his shared  suggestions, those tweaks I have made consistent with his theories have been spot on. I have no reason to doubt his favorable reviews. 

I had a pair of 1.7s that I loved.  I agree with jaytor that they could project an exaggerated image.  I think it was a Duke Ellington song in which the voice seemed to be coming from an enormous head.  I listen mostly to classical music so that effect didn't happen often.  They were superb for my type of music.

Your amp should be fine I’m running my 3.7i with 500 w into 4 ohms never a problem always sound great. I wonder how many of these people saying your amp is barely adequate actually own the 3.7i.
When I had my 1.7i i was using 240 w at 4 ohms and boy did they sing.
With Maggie’s it’s how much current the amp puts out.
I should add my room is 12x 15 so as long as you can give space behind them you're fine. I love the clarity and soundstage of Maggie's.

I agree with mljostyn, johnto and others, Your 400W @ 4ohm should do fine with the 3.7i Maggies and your room size, with care and patience in set up, should be fine
.
To me, the Magnapans of the late 70s early 80s, while having the detail and timber nearly rivaling the Quad, ESLs, the sound seemed a bit thin and less engaging, by comparison. With the later models (particularly the .7, 1.7, 3.7 and 20.7 models) I am very impressed. They are dynamic, with clean accurate timber and detail, yet are very full and engaging.

In my 14’W x 23’D x 10H audio room, my 1.7s do a great job - presenting a deep, wide stage with a very detailed and solid image. Augmented with a ADS sub the sound is full and musical, yet detailed with convincingly good timber. I am driving them very well with a Rogue 100W per side integrated tube amp.
IWhen moving up to the 3.7i, I may need a bit more power, but even so Mike @ mijostyn thinks the Rogue may be enough.
In my, or your, space, I believe the 3.7i would provide the same incredible sound as the smaller 1.7s but with an even larger, fuller stage.


For most genres of music - particularly Jazz, Pop, Celtic Country or Old Rock (Bob Seger, Van Morison, Pink Floyd, Fleetwood Mac, etc.) - I can not think of any speakers, at anywhere near the price, that do so many things so well, as the Maggies, when properly set up in a good room and integrated with a good sub......Jim
