JADIS JA80 with 6550 or KT 88 or KT90 ?

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 .

I don't think the Cayin is as versatile as the Jadis in accepting various tubes. btw did you feel obligated in buying the speakers with the A88? Which city do you live that has Cayin to audition?

No , I did not feel obligated at all . The dealer is in Clearwater, Florida .
