Jadis JA30 Mk2, how great???

@alexatpos I might agree that the original Jadis JA30’s may not have had enough power at 30 watts/ch to show the GH’s at their best; but the new model Jadis JA30 Mk2 has an output of 48 watts/ch ( due to its larger and more robust power transformers and its use of the new KT150 tube).
The new model is as i stated in the reference from Charles above.

I have not had the chance to try the Jadis and do not want to derail the thread, however, I have paired SF GH with Pathos Inpol 2, Burmester 956mk2 and Krell Evo 302.

Before I tryed the Krell I thought that the other amps are quite sufficient, but to my surprise (I am not a fan of big ss amps) it was the Krell that really 'opened' those speakers.

Few times I have read that some of the folks have even set amps with SF GH and by no means I would argue with anybodys choice, but imho those people with such or similar low powered tube amps will never hear everything what that speaker has to offer

 @alexatpos  I use two different amps with my GH’s. Not at the same time. The Jadis mono blocks are my go to tube amps, but I also have a modded Jeff Rowland model 8 t ss amp. This amp is a real brute, puts out 250 watts/ch into 8 ohms..and doubles into 4 ohms etc. I can tell you that the gain position on my preamp is about the same for both amps, and that the Jadis JA30mk2 doesn’t even break a sweat handling the GH’s. Same goes for the ss amp.

Daveyf, as I have not heard the Jadis, I have no reason to doubt your words. 

500 watts available at 4 ohms from the big Rowland transistor amplifier versus 45 watts available via the tubed Jadis . And the Jadis is an equally competitive amplification choice. There’s so much more involved than quantity of power in achieving superb sound quality. No doubt that the Jadis mono blocks have excellent quality transformers and top notch robustly constructed power supply.
