What are some of the downsides of owning a Magneplanar .7 or 1.7i ?


Thinking of moving up speaker wise, and so am considering  the fabled Magneplanar speakers, that is, either the  the .7, or supposedly new 1.7i.   (BTW, I am not sure the Maggie .7 is necessarily an upgrade, and has less bass than my current box speakers...see below)

Besides "Maggies" having outdated speaker terminals that might be a struggle with banana plugs,, and they are generally power hungry, I am curious if anyone can honestly tell me of any other downsides of this design.  For the last 30 years, I have owned several traditional box design speakers. 

I currently have a pair of Golden Ear Technology model 7's....which I like and generally sound good However, I  would like to confirm what a planar design brings to the table in sound quality. I have read many times about the box-less sound  provided by this design, and its wide sound staging and low distortion. 

I think I have enough power with BAT VK-200 amp (100RMS) to drive the .7, but not sure that is enough to drive the MG1.7i. to higher volumes The pre-amp is a Conrad Johnson PV-14SE. 

The listening room area 12 X15ft, but opens into kitchen/dining area divided by a medium size couch. The rest of the space is approximately 12X18ft behind the sofa with a stupid counter island ( so I cannot move the sofa back any further.. The ceiling is 8 to 9 ft feet high ( not a cathedral ceiling, praise the Lord) . It is a bit of haul to the dealer I bought the Golden Ear T's from who also carries Magneplanar line.  All advice welcomed.    Thanks, SJ

Instruments on a stage all have varying intensity/ dynamics but the Maggie’s homogenized everything into sonic wall paper. It had tone and colour etc but seemed to lack varying dynamics within that field. Like I said hard to explain.

I think that's a very good description of their sound. An album that really highlights the lack of varying dynamics - especially at low volume - is Supertramp's Breakfast in America.

 I also agree with a phrase I encountered in one review: "Maggie Mist." In my system, everything sounded like it was a bit diffused. The imaging was wide and deep but lacked precision. This really isn't surprising when one considers that the sound is radiating from an ~ 5' tall surface. Many claim that one strength of Magnepans is their clarity, however, I felt that the diffused sound really hindered them in that regard. To my ears, the 1.7s weren't any cleaner sounding than most $2K pairs of dynamic box speakers.

I have been using Maggie panels for the past 7 years, first with a pair of 1.6 in my small 11' X 17' room. I liked them so much that I moved up to the bigger 3.7, but that was a mistake because my room just couldn't cope with the extra energy, not just in the bass region but all round. I struggled with them for 2 years and finally gave up & moved down to 1.7i with 1 DWM. They were driven by Berning Quadrature Z mono blocks (1.7i) and Plinius SA Reference (DWM). The sound was wonderful but I got itchy and got myself a pair of expensive Raidho D 1.1 bookshelves last month. To my dismay the super costly D 1.1 does not outperform my humble 1.7i across the board. Sure the bass punch is more pronounced but that's about it. Just shows how excellent value Maggie represents.
A cheap upgrade is to change to decent speaker binding posts (the originals break fairly easily anyway) and bypass the high frequency resistor pot & fuse holder, which shouldn't be a problem providing your amp is reliable without risk of DC offset.
The biggest downside of having Maggies is that you will be spoiled for life. Everything else sounds like boxes.
