Quad vs. Martin Logan?

Yes, the Maggies are a different technology, but more like electrostats than cones, much closer in sound reproduction.

I agree with Jeffreybehr regarding his Quads. I really think those (along with the SoundLabs) are the pinnacle of electrostat sound.

Then again, it's all so subjective. Every speaker mentioned here sounds great, really. It becomes what your preference is.

BTW, glad to here about the ASL amp. I really want to try some Hurricanes with my Maggies when my kids are a little older, so I don't have to worry about them getting burned by the tubes. Good luck.

Ditto. I owned a pair of MLs and never got used to the tonal difference between the Mylar and the enclosed woofer. Yeah, MLs look cool, but they don't sound like what hi-end can sound like.

Most of what I could add to the original question has been responded to by others, however no one, that I noted at least, has touched on one of the differences between the Quads and some of the others. Quads act much more like point source speakers than Sound Labs and Maggies, both of which can add more of sense of height, similar to dynamic linestage speakers, which is missing from the Quads unless you have a optimal set up. Personally, if I had the bucks and the room, I have those bigggg SoundLabs.

I own a pair of the smaller (ISIS) Innersound speakers and before I bought them I auditoned the Martin Logans, Quads and Magnepan 3.6Rs. Never heard the SoundLabs, but haven't read anything negative about them.

I chose Innersound because they integrated woofer to panel better than Martin Logans, played louder than the Quads and were more available than the 3.6Rs (At the time there was a 6 month wait for 3.6Rs). My overall preference/ranking of the 4 is:

Magnepan 3.6Rs
Innersound
Quad
Martin Logan

You need to listen to as many as you can, and don't forget things like associated equipment, room size and WAF (if appropriate)

Newbee, I'm right there with you. Those and the Maggie 20.1's are what I covet for my "ultimate" media room. I plan on adding one to my house in 2yrs under the guise of a "Gameroom". Don't tell my spouse!!
