Any JBL 1400 Synthesis Array owners

@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. 

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.
