Any JBL 1400 Synthesis Array owners


I have a pair and am interested in what amps you have tried and the results. I am currently using a 70 wpc tube amp to great effect. I will also try the Quicksilver 90wpc Silver Mono and MFA M 200 in 100 wpc triode mode. The Bryston 14BSST is great but too heavy for me so I reluctantly sold it. Perhaps trying a 3 BSST in the future for a SS alternative.
Using an Aesthetix Calypso preamp.

I traded my 1400s in on the 4367s, I had only owned the 1400s for about a year or so and was very happy with them. The 4367s not only play louder, they remain clear and show no signs of strain at higher volume. The 1400s could sound a bit compressed (for lack of a better term) when pushed hard. The 4367s are also more dynamic at any volume. I used a McIntosh room correction unit with both, MEN 220 I think is the model number. I think the 1400s are very good, but the 4367s are significantly better. They should be, for the price difference. 
I've owned my 4365's now for 6 years and love them to bits. I've driven them with an Ayre V-5xe which was nice, but a little dry. For the last 2 years i've been driving them with the Audio Note Kits EL34 mono blocks at 40w per side. The tubes sound so much better then the Ayre. Much more texture and body. 
Disagree on the comment that the 1400s compress. Might have been an amplifier problem because I've pushed mine very hard using a 400WPC amp and they sound exactly the same but louder the higher the volume.
