Have you gone to Galen Carol Audio? Check out the audiophile groups in Austin I am sure someone has some of the speakers you want to hear and will let you take a listen.
I know if you are in Houston, you are welcome to listen at my Casa. Also, Sound World in Houston carries a ton of great gear, including the Paradigm Sig S8, which for what you seem to be looking for, it right at the top of the list.
I saw Galen about two years ago when I was looking for a new tube amp. I wanted a Jolida, but he had none in stock nor any other tube gear at the time. He wanted to sell me solid state, but I did not want SS in the wattage range I could afford then. I have since recently sold my tube gear and have gone solid state. Hehe, go figure.
While there, I listened to a pair of Epos monitors, and a pair of Spendor S5e smallish floor standers. I remember being blown away by a magnificent pair of Quad 989 electrostatics. They were the finest speakers I have heard to date. Since I was there to audition amps and CD players, I did not pay quite as much attention to the speakers.
I would like to go back for another visit before I decide what to buy to hear the Spendor S8e, Quad 22L2 and Reference3A Veena. He may still get my business yet.
Also, thanks for the invite. I just listened to the new Magnepan 1.7 and really liked their sound. I would wager those MG-3.6r Maggies sound awesome. How would you compare the two if you have heard them both?
