Broken CAT

I recently dropped my CAT SL1 Ultimate MKII and it cannot be played. I have a CAT JL2 Amplifier so I thought the CAT Pre would be a most nautural partner. Since I did not want to wait for repairs, I bought a used Lamm LL2 and was very pleasantly suprised. I'm no reviewer, but I felt that in some ways the Lamm worked perhaps as well if not better with the CAT amp - very musically engaging. So now I'm wondering what experience some of you may had with successfully using a non-CAT pre with one of the CAT amps. If it helps to know, I listen mostly to jazz and folk rock, mostly acoustical instruments and I'm using Merlin VSM-MX speakers. Thanks.
