Cat sl1 owners: wich tube amp for this pre amp?

I've a Cat sl1 signature mkii and totem forest speakers. I tried a lot of tube monos but i'm really in trouble to find a right match. The last i bought are two vtl mb 125: the sound is too bright for me...too detailed. I lissen to jazz and classical. I ask suggestion for a good tube monos or stereo to drive my totems (tube only please!). Budget 3000-5000 € (i'm in Italy...), stuff i'm considering: arc (vt 220, classic 120), manley (snapper, 100/240), jadis (i auditioned ja 50 and liked them...only few bass..)
Thank you for help
Buy a CAT amp. You will never find a right match with different Manufacture (May be right but not perfect)?
