Magnepan 3.6R vs. 2.7QR

Thanks for the information guys,
i wish i could audition the 3.6QRs on my system, but i guess that is not possible (unless i buy them)
I will try to arrange an audition with a 3.6QR seller.
How about blown tweeters, is that a common problem with 3.6QRs?

Hi Neal.
Thanks for your post.
I would appreciate if you could post Schneider's website.
Thanks

I must add that i did upgrade the inductors on my 2.7QRs after seeing the cheap factory inductors that came with the speakers (basically wire spools of copper wire)
and it made a difference in the sound, particularly in the bass.
On the other hand i am skeptic about anyone being able to hear any difference between the steel vs. Copper jumpers in a double blind ABX test..
