Ref. 3a , GMA & Tyler compare ?

I'm using the Reference 3a De Capo i speakers on 28" Skylan stands in a small room (11 x 16). These speakers are partnered with a Blue Circle BC-3 tube pre and Simaudio W-3 SS amp. I'm very pleased with the results at both low and high levels. I think that you'll get better results with the De Capos if you have tubes somewhere in your audio chain. I haven't heard the 2 other speakers which you listed.

^Think #A with no crossover will get most nods.You have menioned for me what is and acid test for speakers.Apt and condo dwellers plus folks who have just goten over Led Zepplin and Who at live listening levels want speakers that have dynamics even at soft volume levels.I got a pair of Audio Physic Sparks for a buddy and kept them a moth.They were so small interms of width and depth it was fun pulling them out for near field listenming listening sessions (why if I get a 2A3 or other flea powered amp am interested in Cain and Cain Abby's because you can order them with "normal " and near field Fostex drivers and for second system, I prefer latter.Anyway wehn asking a sellr of Sparks why ghe didn't get the Tempos for bigger stage and bass at nott much more money he said tempo's needed to be pushed to opedn up.This is why many oldder rev\civers (evenm a recent 90's Mac pre I had used to have loudnes buttons mainly for bass but I think many folks wanmted to hear dynamics).Gingko makes aneat looking $2500 tube on a tube with three 6 and half inch drivers with top mounted tweeter.Wilson Benesch has $8K Discovery with isobaric loading as well.Great for extra bass in small canbinets but in past iosobaric lines have needed to be pushed to open up which is a shame.Like I said have heard 3A's have good dynamic sense at softer listening levels.Other brands mentioned are respected but doen't know enough to comment.But have a buddy who is giving Reference 3A's some serious consideration.

with the GMA first order cross-over will it need room to develope its sound? They are truely amazing speakers wich I spent several hours really enjoying them.....just not sure how far you need to be away from them to sound ideal.
