Jadis JA30 Mk2, how great???

Daveyf, 
Congratulations! The Jadis JA 30 MK II are beautiful visually and no doubt every bit as beautiful sounding.  Some say that the SR Guarneri Homage require considerable power to get the most from them.  The JADIS 30 MK II provide up to 45 watts class A Per channel.  This tells me that they have exceptionally good output transformer and power supply to match so well with these speakers. Based on your description this pairing is superb.  I predict that you'll be very happy for many years.

Thanks, Charles. The SF GH are not that easy of a load. IME, they will not work with very low powered/flea powered amps. However, with the Jadis JA 30 Mk2, as you pointed out, the transformers/power supply are exceptional and since I am using a small room, the 45 watts/ch works fine.
The sound is absolutely amazing with the new KT150’s. Incidentally, these amps also have NOS Siemens tubes in the driver stage, a significant upgrade over the stock EH’s, IMO.

I am glad you have found beauty in the Jadis JA30ll amplifiers. As I stated in this post prior those amplifiers bring as much emotion as any amplifier I have ever used in my 40 years of listening and I have owned quite a few marvelous creations. The bass is very good for their power rating combined with the Jadis magical midrange.
As we both know, this hobby is all about matching each component to the listening environments and their mates. With that said this is quite difficult and when you score you can celebrate.
Have one on me and enjoy the music!

@daveyf  Congrats on the new amps they are certainly  stunning to look at I can only imagine how great they sound! There is something very special indeed about a good Class A pushpull  tubed amp and good transformers are key. Obviously Jadis winds some fantastic transformers for their amps. Happy listening!

Tonight I had a long listening session with these amps. The new design of the mk2 and the KT150 tubes make this Jadis amp the most resolving and life like sounding amp I have ever had in my system. The Jadis JA 30 mk2’s drive my SF GH’s with ease..allowing the speaker to define the soundstage with great precision. The highs are as pure as any amp I have ever heard and are ( at least to me) a revelation with the silk domes that the GH’s utilize.
With certain wind instruments the sound of air escaping through the horn section can easily be heard and the ‘blat’ that distinguishes the various openings of the trumpet and the sax are now eerily realistic.
IMHO, if these new Jadis amps will work with your speakers, they should be on your very short audition list.
