Magnepan 3.7 or PSB Synchrony One?

totally different world.

The Maggies present a huge diffusive image, stunning high end detail, boomy bass, don't play loud, difficult to drive.

PSB

Well focused sound stage, great bass, excellent dynamics, smaller overall image size, easy to drive.

Thanks Audiooracle
I knew they are entirely different sounds.
I like the larger image and speed of planers but if they are too diffuse that bothers me a bit. They are also more power hungry raising the entry fee. If the PSB presents a small image that's not likely to be my best choice either.
I've owned 1.6's and found them a little on the 'warm' side for my tastes along with marginal bass (I know the bass can be corrected if carefully matched with a sub)
They seemed to also lack some of the dynamics of conventional designs. I can't say any of that would apply to the same degree with the 3.7 though.

The bass of the 3.7 is anything but boomy.

"If the PSB presents a small image that's not likely to be my best choice either."

PSB Synch throws a wide soundstage, deep 3d image making the speakers disappear. The mids are very articulate, however the metal tweeter can sound bright and forward if not well matched with rest of the components.
My 2 cents.

The Synchrony One's you will want to listen to for hours, the Maggies you will not. I find all Panel speakers fatiguing compared to box speakers.
