CAT Preamps vs Amps


I'm a proud owner of a CAT JL2 amplifier. Most of the threads on Audigon say great things about CAT's amps JL 1-3. People laud over the musicality, transparency and dynamics of these amps. However, when it comes to the preamps (Signature and Ultimate versions), it seems like the reviews are a mixed bag. In many cases, some CAT amp owners use other preamps.

Therefore, are the current CAT preamps (Ultimate) as good as their amps in terms of musicality, transparency and
dynamics? Are they on par? If not where do they fall short compared to the amps? What are better matches?

I read John's (Jafox) long post. (poor John he was "compelled to post!! LOL!)
I think that John underscores my point - know why people are using other preamps, evaluate whether similar or exact need exists in your particular system & audition/purchase preamp accordingly.

To that effect, I think some of the AN-Kondo & AN-UK preamps like the M6 might go well w/ a CAT power amp. AN components are mostly about music & PRaT rather than being exacting & they *could* provide a suitable balance to the overall sound. The M6 is e-x-p-e-n-s-i-v-e but then it seems that you are swimming w/ the real big boys so it should be in your budget. FWIW. IMHO.
I ran the CAT SL-1 Mk. 3 preamp with built-in phono stage in my system for several years and eventually replaced it with the Lamm L2 (line stage) and LP2 (phono stage). The Lamm phono stage came first, and it handily outperformed the phono stage built into the CAT. While the phono stage in the CAT is phenomenal for the money, IMO it is really not competitive with the very best stand-alone phono stages. About six months later, I replaced the CAT line stage with the Lamm L2. To my ears and in my system, the Lamm L2 was clearly superior to the line stage in the CAT.

Just my $.02.
I heard Jafox's Aethetix AND a CAT SL-1 Sig III in my system, and I MUCH preferred the Aesthetix. It was in nearly every way (except maybe bass) better to my ears than the CAT. I found the cat sterile and slightly artificial (but not bright) by comparison.

That's not to say the CAT preamps arent great, they are, but just not for me. At the time, I had Berning amp with Verity Parsifal Encores, and an AA Capitole II feeding the mix. Now, to be fair, i did not have the very best tubes i nthe CAT, and that may have had something to do with it as well...
One thing I forgot to mention in my novel above was that I first heard the JL-2 with the Blowtorch line stage. This pairing had far far more resolution and dynamic contrasts than I will ever have with the Aesthetix. I suspect for you ultra transparency diehards, you better hurry up and order one of these before it's too late. We had the CAT preamp on for a brief moment but immediately we went back to the Blowtorch as something was so very "right". When I go back there in Dec with the JL-3s, I hope to report on the CAT preamp with this as well.

Art, I wanted you to get that Ultimate more than you did as I was dieing to hear it over here. Now I must wait! You should see the floor in here with tubes all over the place. I got a ton of 12AX7, EL34, 6922 and 6SN7 and am swapping all sorts of combinations in the Callisto and Io trying to squeeze out a wee bit more headroom and little less noise.
