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.

I second what David has said about modifying the BAT 75SE(150SE). He has listed the mods in order of increasing difficulty - easiest first. He has advised and helped me make the mods to my 150SE amps. If one is not intimadated by a soldering iron, these mods are quite do-able for the average audiophile who wants to get the most out of those amps.
Highly recommended.
Thank you David and Rgurney,
I read about your mods, and that's something I might do, if I finally decided to go with BAT.
One note on V-caps, though.
Some Supratek preamps owners changed Auricaps to V-caps,
and some of them decided to go back to Auricap, not liking what changes V-cap introduced to the sound of Supratek.
Actually Mick Maloney (Supratek owner) was offering upgrade to V-caps, but after listening to them for a while,decided that he didn't like the sound.
I know, this experience cannot be transplanted to BAT, but still, there is something to consider.
I guess, same goes for silver wires, some people like it, and some don't.
Point taken, Maril555. Some Supratek owners raved about the change with V-caps as well. Not sure how long .."listening to for awhile.." is. V-caps do require breaking in. Different strokes.......
Mick said he gave it 400 hrs.
You're right, we do have very different tastes for sure.
Hi Maril555:

Yes, I still run my VAC Renaissance 140/140 Mark III's, but I am thinking of selling them, as I would like 24/7 access to my system and can't justify firing them up if I want to listen to music for just a few minutes or listen to NPR in the morning before leaving for work -- as much as I love them (my wife does, too, funny enough, as she does not care about audio), I would like the flexibility of a solid-state amp.

Audio Auricle certainly knows what he is talking about and is a good guy with a lot of hi-fi integrity (Hi Dave). That said, my closest hi-fi friend ran the $50K Limited Edition CAT monoblocks for almost three years, and through him and his accumulated knowledge (he corresponded with at least a dozen other CAT amp owners in an attempt to maximize their performance and use, tube choices, A/C line supply questions, mechanical isolation, etc.), I learned quite a bit about them. I must say frankly that they sounded better than my VAC amps (which themselves ain't chopped liver -- all point-to-point wired, eight 300-B's per side, excellent output transformers, and really high parts quality -- they cost $28K). At least the $50k Limited Edition monos do -- more linear and transparent, with iron-fist bass control and dynamics. Persons running later iterations of the amps, many with vast experience running other amps in their systems, likewise said that the CAT amps stand out for dynamics, bass control, transparency and build quality. Again, the only real issue was reliability -- my friend nicknamed his amp "the popcorn popper", and everyone he knew with the amps seemed to be saying the same thing. The owner/builder is also reputed to be a bit of a character, which did not help.
