JADIS JA80 with 6550 or KT 88 or KT90 ?

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 ?

Saki I plan to stay with the Jadis tubes in the JOR. These are very expensive tubes and to get any quality that will equal these 90's will cost me a fortune. I suggest you stay with the cayin tubes, which are no doubt FIRST CLASS tubes. IOW don't go changing anything. What you can take a look at is your digital sourse and speakers. Do these 2 match up with the A88 quality. You gotta look at this system thing with some logic. Changing tubes isn't goning to make a class B speakers/digital sound any better.

Bartokfan ; I agree . I just acquired this amp with a pair of Ref 3a De Capo i's , which I auditioned together . So I was just thinking ahead , right now I am quite pleased . But we all know how long that can last !!! I would be interested in knowing what my options would be , when that time comes . Just trying to learn .
