BAT 75 SE vs. CAT JL2 or JL2 Sig.


I would like to know how this two amps compare.
I do realize the price difference, but still, would like to hear your first hand experience with both.
I'm especially interested in the differences (or similarities) in the areas of tonal character, dynamics and ability to play complex, dynamic music ( I listen to classical, rock mostly and everything else in between)
You can see my system below.
I should also note, that I used to own BAT 75SE in the past, albeit with different speakers and preamp, so I'm fairly familiar with this amp., and have been thinking about trying it again.
Never heard CAT before.

The CAT amps are arguably the most powerful tube amps ever made ("powerful" in the sense of their wattage ratings being almost meaningless -- they can drive virtually any speaker to loud levels cleanly). They also do finesse, especially the all point-to-point wired $50K limited edition monoblocks with the outrageous 55 lb. output transformers. The newer models with circuit boards aren't chopped liver either.

The only downside is that they could be less finicky about requiring only the most carefully vetted output tubes, and when tubes blow, they take out resistors, which, given their outrageous weight (192 lbs. each for the limited edition monoblocks), makes owning them an obsessive's pastime (the comparison to Ferrari's best before those cars became reasonably reliable is not off the mark).

In short, while BAT makes a very fine product, the CAT amps are an extreme product that is without peer in my experience.
Raquel,
Very thoughtful and knowledgable response, as always.
If I'm not mistaken, latest CAT JL2 Sig. use fuses, instead of resistors.
Do you still have your VAC 140/140?
As you probably noticed, I'm using VAC PA 90 C1 in my system, (as a temporary solution, while I'm looking for a more permanent replacement).
I have a feeling, PA 90 doesn't have enough "drive" to play big symphonic pieces with enough dynamics on my speakers (they are 92 dB, 8 ohm).
I was just wondering, if you could share your opinion on VAC PA 90 C1?
