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 own a pair of 1000 arrays - wish I had space for the 1400 but alas. I power them with a Denon PMA 2000 IVR integrated which might be familiar to some of you. Ultra High Current MOSFet design, nominal 80 w per channel but benches at 125 at 8 ohms and doubles that exactly into 4 ohms.  It is a beast of an amp however, at 52 pounds, dual mono, it has 120 amp per channel peak current output, Kimber 8TC speaker cable and: The sound is absolutely sublime! I almost never can get it past 9.5 o’clock on volume. And its not ’loud’ its dynamic, neutral, life like, shocking and an absolutely joy to listen to, even and especially at low levels where they do not shrink! Amazing. I’ve been told that the JBL Synthesis 800 amps, bridged, do absolute wonders on these speakers, although its hard to imagine since they already sound revelatory now. I’d like to try them eventually once my space allows for it, however right now I almost wonder if I’ll ever get around to it, they sound so good with the amp I have.
I had a pair of the 1400s for about a year, I thought they were very good. Used a McIntosh MC452 to drive them. I would still have them but I ran into a very good deal on a pair of JBL 4367.
@tlong1958:

How do the 4367s compare to the Array 1400s, and what did you do with your Arrays? 

I think I might have encountered a similar deal and all that I can tell from the specs alone is that the 4367 is sort of a hybrid 2/3 way design and it's much more efficient (94dB vs. 87 or 88dB), so likely easier to drive.

But what about sound quality?  When considering the fact that the 4367 will logically be louder for a given setting, what other differences are there? I'm pretty impressed with the 1400 Array and I don't have the option of listening to the 4367s (unless I take a plane flight and hear them in a strange room, probably equalized), so I'm genuinely curious. Are yours equalized? What do you prefer in the 1400s and what do you prefer in the 4367? 
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.
