JADIS JA80 with 6550 or KT 88 or KT90 ?

Trejla , I feel I need to try the JJe34l in my JOR.
Now do you suggest I get the DA30 intergrated and experiement with 34 and 77's? Like you I am after vividness and brilliance, nothing flat sounding like the EH KT88's.
Will the DA30 accept 77's?
I'm not really interested in rollojng the 2 pre tubes in the JOR, as the changes will be too small to notice.

Trejla, I'm will to give up bottom end for brilliance in the highs. I do not like flat mids/highs. So that would be the E34L tube for sparkling highs/mids, correct? I also like very analytical sound stage, nothing mushy/all jelled together. Like the EH88 did.

Trelja is the most knowledgeable resource about tubes that exisists in my web travels and I have learned much from his previous threads. That said, I would still only re-tube a Jadis amp directly from Villedubert. Unless you never liked the sound of the amp to begin with.

Yes I just talked with Pierre, he said the best Kt88's are those directly from Jadis, but cost is $$$. I'll stay with the 90's. You know when you pick one tube over another, quality tubes I'm talking about, class A sound, you give up something for something else. What the 90's have the 88's lack, and visaversa. From talking with Pierre, the DA30 gives more power than the JOR, but I really don't need more power.
I'll stay with the JOR and get the Cayin 88 as a second amp.
The 88's in the cayin should be on the level that Jadis uses in their amps. And may be better than the EH and JJ tubes.
I'll post a note when the A88 arrives, mid summer.

Jadis tube lover that I am, now understand my devotion to the SS SOTA: Hovland, hand built locally, customizable, accessible, affordable, dependendable, reliable, predictable. What's not to love? Just the tax and duty added on to the tubes from France for one.
