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

So what can I say...your answers came very quick. Thank you very much to all.I am first time on this forum.
To Mang53: I have friend who have WP5.1 with Tenor 75Wi and Transparent Reference MM cables. For my taste the sound of his sistem is incredible-musical,rich-full,air and super dinamic with sounstage to die for.I have the same music taste like him.For him the Halcro and WP7 combination is to steril so I suppose for me,too.
To Jafox: thank you for your answer but If I pick WP7 then I can not afford me JL-3s but JL-2 Mk2. I will see and give my report as soon something serious happen.

Ah ja, my friend of which I spoke have problems with Tenors 75Wi because they dont give WP5.1 enough power when listen on more then medium volumes-big classical music and rock...

My room have dimensions 7,8m X 4,2m and is 2,5m high.
I heard that CAT power amplifiers drive capability is very good so I suppose it will match my room dimensions with WP6 or 7.
One more question: How would be sonicaly if I put CAT jl-2 Mk2 and Lamm L2 reference preamplifier in the sistem with WP6 and Transparent reference XL(MM technology) or would be better to pick CAT Ultimat Mk2 or even Manley Steelhead which is phono and active line preamplifier together?

Thanks Raquel.
Bob, the CAT amplifiers dont have balanced inputs?! I am I right?
So I suppose you used RCA interconnects between Lamm L2 and JL-1. What would you say- which is the max. lenght for rca-interconnects if I put them between JL-2 and Lamm L2 preamp and not lose any quality in signal?
Thanks

I will need approxima. 20-foot(5m) interconnnect for my sistem. From your words I sum there will be no problems do it this way.
Thank you.

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.

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.

Good suggestions from both, since I will not need any active pre.
So lets sum up: Kuzma combo with Aesthetix Io phono with volume pots to CAT JL-2Mk2(JL-3Mk2) to WP 6(7) all wired with Transparent Reference MM cables! Something is missing...
The cartridge! What is your suggestion, which would match idealy in this set up? If,then I preffer more warm sound not cool and analytical. The best would be neutral.
