Cat jl1 monos or Cat jl2 or Red Rose model 1

Hi daveyf
Not possible to listening.....
I'm in Europe and here is very difficult. There is no distributor in my country and not for sale a used  item.
Now i have a ML 336 power amp. It has enough current for extremas but I think these speakers could be fly in another dimension with C.A.T.
Would this be a great headway?

Meanwhile my JL2 signature arrived.
I tried it with my ml326s but it did not make a big impression for me.
It did not sound like a "superamp".
But with  the CAT sl1 signature it came to  alive.
So Im really impressed. 
The jl2 equipped with kt 120 tubes and unfortunately slowly must to buy a new set of tubes.
If anybody has experience about tube rolling in this amp please let me know. 
6550 or kt120?
And wich brand?
I read many threads about in this theme but not exactly with jl2 signature.
