Jadis JA30 Mk2, how great???

Well I made the trip to Chicago as I said I was going to do. I took my older JA 30's and my Living Voice speakers to really hear the difference.

After spending an hour in Chicago traffic I finally made it to George's Salon. George was listening to his new Gamut RS7 speakers driven by the Gamut SS monoblocks and they sounded splendid.

We moved the LV into place and warmed the Jadis JA30ll and rolled the que. These amps. are in another league. Gone is the fatter midbass/bass and replaced with a tighter and more tuneful extended bass. Midrange is still full and faster and the top end more open and extended. On my speakers the bass tightened significantly as the speakers lit up with the power. The amp. played with precision and sounded like it was in control top to bottom. As it turned out I ordered a pair and await their arrival.

On the way home George called and said the Gamut speakers that he admires also took a liking to the Jadis amps. I did not get to hear them on the Gamuts but George said it is love at first listen and these speakers are more like 88 DB into 4 ohms and they show plenty of power. 

For the money it appears these are a no-brainer and will be able to drive a lot of speakers at their disposal. I can't wait to get mine and anticipate this will be my mid-power amp. of a lifetime.

Hi Butler:

I only heard the amp. with the KT150's but it was sure good. The amp. has strap changes internally for the other tubes so time will tell. One thing to remember is that none of the listening involved "cooked" gear and I personally find that very important with tubes and transformers. I could hear the amps. getting better and better as time went by and they had a much blacker background.....they are quieter for sure. George did not have them cooked when I got there but that was Ok because mine were not either. At any rate they were in way more control than the older amps. and the bass had slam and control which my older ones did not have. My older ones never got cooked with the time I was there but I am certain it would not have mattered. So to answer your question I am not sure I am in love with the KT150's as much as the improvements to the amp. itself with the smaller tubes? I still have to investigate the answer. I have no doubt the smaller output tubes will be magical in it also as I did note the caps. were a tad larger and I believe the outside of the transformers might have been a tad larger also. Hope this helps.
