CAT JL-2 Mk2 vs LAMM M1.2 ... on WP 6 or 7


I am considering to by me Watt/Puppy 6 or 7. I dont know which amlifier would be better with this speakers- CAT JL-2 Mk2(JL-3) or Lamm M1.2(1.1),ML1.1, ML2.1 ?
Can someone tell me the difference?
The cables are Transparent audio Reference XL(MM), source Kuzma Stabi Reference with Airline.Preamplifier probably the same brand as power amplifiers.
My music taste: most classic music,jazz and then some rock...
I prefer complexity , texture, neutrality and dinamics(macro and micro) within airie sounstage- but most important it must be music!
Thank you.

Raquel: I don't think it was ever Mr Stevens' intention to sell $50k amplifiers for the long haul. Nobody survives on this very long. He simply needed to recover the R&D costs for the all-out assault to develop the finest output transformers that I suspect he was very eager to do. Surely a lot of different materials, topologies, etc., were tried and ultimately not acceptable until the one finally to meet (or come as close as possible at the time to meet) the desired specification.

We all know a lot of software is re-written and much hardware is thrown in the recycle or trash bins for the sake of R&D. The cost of time and parts to build a production unit does not at all reflect the cost it took to get there. And with a "limited" production run, the recipients of those units pay a high cost for any improvements.

Do you really think there is a $20k, a $10k or even a $5k cost in the ultimate hardware/materials updates to the JL-1 signature to make it an L.E.? Of course not! The sonic improvements from this effort could be phenomenol. But the price here is all about R&D costs to achieve that last improvement of the JL-1 before focus was to shift to the next generation amplifier. I suspect the ultimate cost to push this new technology into the later models was rather low once Mr. Stevens had the materials and process in place.

Rather than wait to recover these costs on later amp designs, several JL-1 amps were obviously available for a "limited" production run with the latest transformers. And no doubt Mr. Stevens made other improvements that he had discovered along the way. It is how engineers work. 8-)

Once the L.E. costs were recovered, the Signature and Limited Edition suffixes could be removed as the new JL-2 and JL-3 models were soon to follow. And now we have already seen a JL-3 signature appear that according to Brian is $8k more than the standard JL-3 with most likely improvements beyond just the output transformer. Again, I am not surprised as I have read many articles that Mr. Stevens is constantly improving his products but does not follow each update with a new model suffix nor with a higher price that we often see elsewhere in this industry.

Do we need to learn of a L.E. model at a much higher price to finally feel that the JL-1 L.E. has been replaced by a new top CAT amp? That seems rather silly. Perhaps when Mr. Stevens is eager to do another all-out assault with one of his designs, it just might end up in a new model at a lower price than the current top model. So what will it be...a $40-50k JL-3 L.E. or a $20k JL-5 stereo amp that takes the current JL-3 signature to the next level? I think we get too focused on the model designation and the costs here.

One final thing: When an engineer designs a state of the art product that takes the world by storm, as surely did the JL-1 in all its versions, that engineer does not simply stop there. There are always things to improve upon. I have never heard of an engineer to be satisfied to simply say, "hey, I did the best once, now second best at a lower cost will be fine from here on". There's simply too much drive to continue to do better and even at much lower cost. And this is the JL-2 and JL-3 series.

Jafox: Thanks for setting me straight on CAT tube amps, engineering, business and expository writing.

Schorly: My apologies for the diversions from your question.
Schorly; did you mention the size of your room? if so, i missed it.

with Watt Puppies there will always be a benefit to more power. based on your sonic priorities (including micro and macro dynamics and a live soundstage) the amp choice will be highly room size dependant. in a fairly small room WP's will boogie on the M1.2's.......but if your room is large it will be marginal for macro dynamics and therefore stage size.

i owned WP's (3.2's, 5.1's and 6.0's) over a 6 year period in a smallish room (12' x 18' x 10.5') and listened to many different amps on them......even in that size room some amps just could not get them going.

most real world amps will work on WP's......just not in every room or to every taste.
My room have dimensions 7,8m X 4,2m and is 2,5m high.
I heard that CAT power amplifiers drive capability is very good so I suppose it will match my room dimensions with WP6 or 7.
One more question: How would be sonicaly if I put CAT jl-2 Mk2 and Lamm L2 reference preamplifier in the sistem with WP6 and Transparent reference XL(MM technology) or would be better to pick CAT Ultimat Mk2 or even Manley Steelhead which is phono and active line preamplifier together?
Schorly: Let me atone for the earlier digression.

I have a close friend who used an L2 with JL-1 Limited Editions and all Transparent Ultra cabling on Salons. Sounded spectacular. The L2 is a solid-state preamp with tube power supply. The output impedence averages 150 Ohms -- it can drive any amp. It will outperform all current and past production CAT preamps in most systems (as for the new $15k CAT preamp -- who knows). As for the Manley, there are differing opinions on how it performs as a stand-alone preamp.

I will alert the friend I alluded to to this thread and see if he has anything to add (he replaced a CAT Mk. III with L2, which he replaced with a Meitner DCC2 that is fed by a Steelhead).
