Jadis JA30 Mk2, how great???

@samhvcc   The JA80 Mk2 is going to give you more power and therefore headroom than the JA30Mk2. It is going to be a much better match to your Sony's. As to whether it will sound better, on your speakers ..yes. However, if one can utilize the lower powered JA30Mk2, then IME the lower powered amp typically sounds better than the higher powered brethren. On my speakers, the JA30Mk2 are preferred over the JA80mk2's. Horses for courses.

Understand, let me think of it seriously, thanks! 

I have finally ordered the JA80MKII, try to evaluate the differences between 30 ,other than the power itself! Since i was told the 80 is another legend comparing with the 30. It may takes some more months to have my 80 arrived. Anyway, the JA30MKII absolutely has enough power for my Sony's after my Sony has been running in for a few more while! Of course  i believe larger power will be better for my main speaker. 

@samhvcc Color me confused. In one post you state that your JA30mk2 was not a good match to your Sony SS Ar1’s...which I can well believe as the Sony’s have a fairly nasty impedance dip at certain frequencies, now you state that the match was good since you burned in the Sony’s, yet you have let the Jadis 30mk2’s go?? Then you tell us that you will compare the Jadis 30mk2 to your upcoming 80mk2, how are you going to be able to do that when you had a pretty bad amp/speaker match up with the less powerful 30Mk2 in the first place?? Obviously, if you have solved your faulty speaker/amp match up with a correct speaker/amp match up ( assuming the Jadis 80Mk2 is 100% correct ( while I know it will be a better match up, as I stated above, nobody knows for sure how better until the match up is done) it may not be the ideal synergy given the still nasty impedance dip that it too will have to contend with!) surely you are comparing apples to oranges....

At the very beginning I said that my JA30 hasn't got enough power for my Sony. I believed it was due to my newly Sony hasn't been running in yet. But having a longer burning in from my Esoteric monoblock. The drive units goes much smoother than before! Plugging in my Jadis again seems working much much better! Then  I would have a conclusion of matching them together isn't be a problem at all. They match well enough for sure now. I would say, enough, but more power, much better honestly for my Sony however! Switching to JA80, which I believe, would extend the potential of Sony, giving more punch & power than the 30. So I would curious to try out how far my Sony can go with the JA80!
