Jadis JA30 Mk2, how great???

Very interesting find indeed.  It is a strange hobby that way.
This CAT JL5 amp. is rated at 120 per channel into 8/4 ohms.
Does not mean much however with the transformers on this amp.
The beauty of it is the first 60 WPC is in Class A and then to AB but all in triode.
The tubes are said to be ran at 1/4 rated output. It all happens to be overbuilt as you know. The Jadis is built much that way also.
This amp. drives these speakers effortless and dynamic and is very smooth. CAT does not romance like Jadis......just tells things more like it is maybe. No flowers on the first date yet but I can tell it is not broke in either.
Does your amps. they put out much heat into your room as your temps. don't vary much like here?

Charles, have you heard Jadis in your system..I think it would be a great match up with your speakers and would certainly lead to a new romance. The new KT150's are, IME, a much easier tube to live with...:0)

Hi Charles:

Thanks for the inquiry. Yes I owned the stereo version of their amps......the D200i latest version. I sold it because tubes belong here and SS gear is not as exciting to me.
I also heard the speakers with the Gamut 250i monoblocks.......excellent amplifiers but I cannot pull the trigger on any SS amps. and they were more money than I could justify. 
Something about the beauty of tubes has me hooked.....good tubes that is. They just connect with me way more. 
The reason I bought the Gamut RS7i speakers is they were very full range and capable of being very dynamic. Coming from horns I found that quality about them.....with correct tonal rendition.
The CAT amp. I have now acquired seems to wake this speaker up. CAT is known for its dynamics and drive so I think all will be well. They are also have a holographic soundstage. Excitement abounds in the music with this amp!  It was a new demo so not quite broke in and it really is marvelous on these speakers.
The Jadis JA80 might have done the trick also but now in retirement the cash flow went south and I know expensive gear will be a hard sell for me when I can't hear anymore ha.
Honestly, I bet you the Jadis JA 30ll on your speakers would be a dream come true. Have you ever seriously thought about that? I never met a speaker that did not agree with more quality power. They just were not enough for the Gamuts. That amp. on your speakers might keep you up at night. I assure you it sounds SET like only way more beauty. I have been there.

Gwalt,
I met Ken Steven’s a few years ago at CES and he was using his preamplifier and mono blocks driving the Wilson Sasha. Those are no doubt impressive power amplifiers. I’m quite familiar with his CAT preamp as two friends of mine had them at one time.

Gwalt and Daveyf I have no doubt that the Jadis would sound marvelous with my Coincident Total Eclipse II speakers with their 14 ohm load. The thing is that I have an amplifier that is superb with these speakers. Believe me, I get the frequent argument for more power. I have both a 100 watt PP tube amplifier and a 40 watt amplifier. The 8 watt Frankenstein SET is better than either.

I suspect that the pure class A Jadis could outperform my PP amplifiers and most likely rival the Coincident Frankenstein MK II. I’ve had this Coincident amp/speaker combination for over 8 years and yet my appreciation continues to grow. Clearly there are other worthy superb amplifier choices besides what I have. Fortunately you only need one superb amplifier😊. 

Sometimes you just find what you consider an ideal musical match. The glorious 300b SET does it for me. Certainly the Jadis does it for you Daveyf, and Gwalt the CAT in your case. I believe that it’s fair to say that we are all thrilled with our respective current systems,.

Fair enough and I agree with your assessment which is where I am heading.......a final destination. I thought I was there until I picked to little power. That's what makes this hobby so difficult and or fascinating at the same time as there are endless possibilities to reach personal satisfaction.
