JADIS JA80 with 6550 or KT 88 or KT90 ?

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.

Bartokfan ; I would be interested in your findings with this tube thing . Or anyone else for that matter . I have just purchased a Cayin a88 . This is my first true voyage into the tube world and am trying to learn .
Does anyone know if the other tubes , mentioned above , such as the kt90's , 77's etc. can be used in the Cayin a88 ? Has anyone tried ?
