With a assumption or two, I can comment. I’ve had all three (assuming you mean the original advent and the ar3). What I find interesting is that these are the speakers I experimented with stacking when I used to do that kind of stuff. Stacked Advents had their own following and sounded excellent. Stacked ar3’s sounded great, but were a little heavy to lug around. Stacked Dynaco’s were the best, great sounding and easy on the back. I should mention that my Dynacos were (and are) 25’s. It was hard to find enough 35’s for a decent stack. I think the 25 must have been one of the best selling speakers ever. They showed up at fleas and tags almost regularly (or, in my case, at least six times). The AR’s had a richness that probably put them on top, but the dynacos had a simple warm clarity that was hard to beat also. The Advents had a musicality, almost a flavoring. Stacked AR3’s required a decent amp. Back then I believe I used a Sansui…I forget the exact model number…9090db..or something like that. The dynaco 25’s could run off pretty much anything. Advents…in the middle. It would be hard to choose a favorite, kind of like choosing a favorite child (In my case it was my oldest, Joe jr. great sense of humor and very easy going), or favorite pet (my black lab, Sadie. Not much of a sense of humor, but sooo easy going), or a favorite wife. (Actually easy…Barb…favorite and only…a compliment I throw her regularly). I’m going with the Dynacos. If I was this smart forty years ago, maybe my back wouldn’t be the minor disaster it is now. I don’t do much stacking anymore. Martin Logans would be difficult to balance. I’d stack my Altec VOTT’s if I could find another pair for anywhere near what I paid for my current ones. Maybe I could get that wall of sound effect like the early Dead concerts. I don’t think I came anywhere near answering your question, but it was fun talking to you.
