CAT JL-2 Mk2 vs LAMM M1.2 ... on WP 6 or 7


I am considering to by me Watt/Puppy 6 or 7. I dont know which amlifier would be better with this speakers- CAT JL-2 Mk2(JL-3) or Lamm M1.2(1.1),ML1.1, ML2.1 ?
Can someone tell me the difference?
The cables are Transparent audio Reference XL(MM), source Kuzma Stabi Reference with Airline.Preamplifier probably the same brand as power amplifiers.
My music taste: most classic music,jazz and then some rock...
I prefer complexity , texture, neutrality and dinamics(macro and micro) within airie sounstage- but most important it must be music!
Thank you.

Well in all fairness to Bob, I can relate to the hassle of having to haul these beasts around. And with this taking up most of 2 days with travel and several hours of listening, that's tough for anyone to do these days. It's easier for me as I already was planning to make the journey, and I previously mentioned to Brian that I would bring the amps with me. If I had not planned for nor had a reason to drive to Chicago other than for this listening session, I'm sure I would have replied much the same as Bob did above.

As for the outcome in the listening session, we all have some expectations here. And we would certainly hear qualities from Brian's burned-in Atma-Sphere amps driving the U1s that exceeds either of the CAT amps.

With or without the opportunity to hear these two amps at one time, Bob and I both realize how fortunate we are to own these amplifiers.

What do you mean about that solution:
source Kuzma Stabi Reference with Airline tonearm(I dont know which cartridge,yet) to Lamm LP2 Deluxe phono stage and direct to CAT jl-2 Mk2 which drive WP6?
Cables Transparent Reference.
Which passive preamplifier would you choose?
Thanks.
With all due respect to Atma-Sphere,I had a pair for about 4 months and you could burn them in till they melt through the floor they are no match for the CAT JL3s.This is my opinion and the opinion of 2 of my audiophile buddies.
Schorly: I would not suggest a passive preamp with the Lamm LP2. I own that unit and, while I think it's superb, it only has 57 db of gain in the MC stage which, on some records cut at low levels and at least with my Koetsu RSP (admittedly low output), is barely enough to play them at reasonable levels, even with an active preamp. I think you will need the extra gain you get running that phono stage through an active line stage. I can vouch highly for both the Lamm L2 and Jadis line stages with the LP2 Deluxe (the synergy between the LP2 and my JP200 is shockingly good).
Rcprince: I know it is better with active line stage but I can not afford me active preamp right now.
I dont have Lamm LP2 Deluxe, but I am searching for phono preamp for Kuzma Stabi Ref. and Airline combo.
I have read only the best about Lamm LP2 Del. phono preamp so I have put it on my short list.
Have you suggestions for me about other phono preamps?
And put some words about differences between them.
Thank you.
