I have spoke with you about this problem in the past.
I sold my CAT JL2 and use a SL Kraft 250. What I never realized before hearing the SL was how sloppy the bass from the CAT is! You never know what you are missing until you hear it! That is only one point, the truth is, the SL beats the CAT in ALL parameters. Better transparency, detail, articulation and extension on both ends of the spectrum. You already have the SL pre (the same one I am using). The SL Kraft is not your typical SS sound. It is the best SS I have heard and doesn't have the sonic drawbacks typically associated with SS sound. The SL pre is the right one for the SL amp (tried the CAT Ult MK2 on it). All this in a RELIABLE no nonsense product. An easy conclusion from someone that has used both. By the way, I have used all tubed systems for most of my life. The SL is the only SS I could live with long term (with the possible exception of Spectral) and I have no desire to return to tubed amps and likely never will.
