Magnepan 3.7

Onemug,

If you can get ahold of the reviews of the 20.1, either the TAS or Stereophile review compares the sound of the single-ended midrange 20 and the push-pull midrange 20.1, don't remember which one it was at this point (maybe both?).

I went and heard them, great sound on a sublime system. That said, when I got home and listened again to my 3.6r's I had no desire to sell them and buy the 3.7.

I will say, that I specifically went back and forth between the Magnepan demo and the VMPS "live" demo since I got trashed on here when I said no way did their speakers image better than Maggies.

I was right, no one who heard both speakers that I spoke with picked the much more expensive modified box over the new Maggies.

The VMPS line sources? I'd expect the imaging to be quite similar, since they have essentially the same driver geoemtry.

Josh358, thanks for the leads.

Can anyone report if the 3.7 did away with the external x/o?

Onemug:
I said the difference was negligible and I'll stand by that....at least from the physics aspect. The driver has about the same DCR. So, they use about the same 'diameter wire'.... Take the wire on the regular driver and smush it out..You'll get a ribbon about the size of that used on the QR panel.
The advantage? It sticks a LOT better to the substrate. LOTS.
Toss in some voicing tests....crossover parts and such and there you go....1.6 becomes 1.7 and so on. I'm not that excited, though it IS a step in the right direction. I just think the nomenclature of 'Quasi Ribbon' is an advertising invention.

Push pull? besides having nothing to do with QR, what is the point? PP leverages the panel technology. Personally, I turn my panels around and listen to the pole piece side, anyway...just like my old MG-1s.

I suspect people would go really nuts if Magnepan decided to use stronger magnets. That would up the sensitivity or power handling or both. Somebody suggested taking the pole piece / magnets off of a dead panel and making their OWN PP design. I'd like to help with that one! Bet it works.
