Magnapan vs. Von Schweikert

You should try Mango Daiquiris. Good for you and gooood for you.
From your musical list I see nothing that won't sound good with the maggies, I also am from the NE so I understand your tastes. Magnepan is a very friendly company, if you contact them and explain your geographical problem they may be able to help you audition the speakers.
Another speaker you may want to consider if you decide against maggies are Avalon Radian HCs(available used). These were some of the best imaging speakers I ever heard, They were the only things that even came close to luring me away from my maggies.

When I was in the biz I needed to eat 6 apples a day, and now I still like apples but I love my maggies :) The only upgrade I am considering in speakers is to 20.1's

For what it's worth I just concluded a search for speakers and was torn between the 1.6 QRs and the B&W Nautilus 805s...that was until I heard the Von Schweikert VR2s. In the under $3000 range, a few $35000 speakers too, the VR2s are the best I have heard in my area.

This whole thing started when I heard the 3.6QRs by the way. That sound stuck with me for a while. However in the same demo with the VR2s I heard the VR4 Gen III SEs. It is an absolutely amazing speaker.

I have heard hundreds of speakers, from travels over the country while working for a speaker company. I have heard the Maggies many times, and they are good speakers. They present some issues for women typically, because of their large physical presence. They sound excellent, and require very good(as do all really good speakers) amplification to sound their best. They are almost resistive, as opposed to reactive load, making the amp see a more consistant load, albiet one which is, depending on your room, requiring a lot of power. The bass, is more rear wall/distance dependant than most speakers, as they require loading the rear wave. Overall, excellent speakers.
I own the Von Schweikerts and find them to be one of the most musical speakers I have heard. They are fast and diminsional, with bass which plummets into the 20hz (almost exactly an octave below an upright double bass' lowest note, open "E" string)region. The rear firing tweeter allows the speaker to sound very transparent, and not at all gimmickey. Overall, I prefer the Von Schweikert, of course, since I bought them, but you are definitely considering two very good speakers. Your ears are the final judge. I think, as a final comment, that Von Schweikert has trumped almost everyone in dynamic speakers at this point.The VSA's are better than almost anything up to about 20K (this is only my humble opinion). Good luck, and if you need any advice you can privately email me, you have a million choices.
