Jadis JA30 Mk2, how great???

Gary, as great as Ken's amps are, IMO his preamps are actually even better. As you know, Ken made his mark with his preamps, and IMO they are still at the very top of the contender list. Absolutely SOTA.
Interestingly, the preamp and the Jadis amps have always matched up well. I can say that my hot rodded/modded SL-1 Sig matches up like a dream with the JA30Mk2. If and when funds allow, go for the CAT Renaissance with Black Paths...as you noticed, your system will take off.
In the meantime, happy listening.

Thanks for the recommend. The JL5 I have is not broke in but it has startling dynamics, speed and contrast....similar to live music. It is the first time since owning the Gamut speakers that I now understand what I heard when I first heard them and why I purchased them.
It is the antithesis of the dead sounding SS camp and or lack of power required.
Thanks for the information.

Gary, the JL5 is a great amp...and like I suspected, and you have now confirmed, well suited to your speakers. As you noted above, it’s all about the mate in this hobby. Get that right, and you have music, get it wrong and you have disappointment. Easier to do the latter, IME.
My SF GH’s work superbly with the new Jadis amps...what’s even more amazing, is that I have to actually turn DOWN the volume in comparison to my far more powerful Rowland amp...which puts out only 250 watts/ch!
But as we all know, that’s not the only part of the equation, it has to do with the quality of the transformers, the ability of the caps and the headroom of the amp, the typical impedance load at the speakers and of course the speakers in use ( room size).. among other things. So 250 watts/ch vs. 45 watts/ch-- and yet the low powered amp offers far more bass punch, dynamics, volume, imaging ability, and ease of presentation! Interesting isn’t it...and something that I strongly suspect most dealers and a’philes have no clue about!!!
Reminds me of a time when I visited a dealer many many moons ago, who was selling the then revolutionary Carver 500 watts/ch ss cube amps...told me they could drive anything. Well yes, but not well, LOL, My 15 watt/ch tube amp obliterated them in an AB...so much so that the dealer assured me that the Carver’s were faulty and he was going to request another pair...
Needless to say, i did not buy much gear from this guy.

Hi Gwalt,
Just curious, have you heard yourspeakers with a Gamut amplifier? A friend of mine heard this brand’s amp/speaker combination and he thought it was very good sounding.

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?
