Magnepan 3.7 or PSB Synchrony One?

"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.

Maggies are hard to drive? They're driving 20.7's with a 125watt at the Magnepan factory. As to to not playing loud, you can sit in my room and I'll bet you can't hear the person yelling at the other end of the couch.

This is a great help - thanks

I hope to see additional input as well. I'm not as able to spend large amounts of cash on audio stuff as I once was so it's important I do my best to make a wise choice.

You need to hear these speakers for yourself, there is no substitute. I own the 3.7s and I haven't gotten much out of the responses on this thread other than each partisan defending his own choice, which is par for the course on internet forums.
