JADIS JA80 with 6550 or KT 88 or KT90 ?

Interesting. Do you guys think if I switch the KT90's for 88's that my JOR will sound even better. The 88's have been recommended, but I didn't feel the need.
Also which 88's are good value. I don't want to spend say more than $200.

The KT88's just arrived, replaced the KT90's with the Elecrto KT88's and after only 10 minutes of listening, promptly placed them back in their boxes. I'd say the quality lost is near 50%. In fact had the original JOR came with these 88's I'd be one very un-happy camper.
Dumb me, doubting the french.
loss in all three fq's in the 88's.
hopefully my seller will take them back with some discount of course,.if not I;'ll put them up for sale here.

The 90's sounded excellent in the first minute.
Sound EXACTLY the same as today.
What I want to know is, does the other Jadis amps that use the 88 have simulairty as the EH88? If so then I may want to ignore the Cayin A88 and other Jadis' that use the 88.
Seems that most all Jadis uses 88's now.
Can the DA30 accept KT90's?

Thinking about it now, I made the best decision in getting the 88's trying them in the JOR. The 88 is not the sound I'm looking for. Its too mellow and vague.
I love the details, sharpness projected by the 90's. No I think I'll hold off buying the Cayin A88.
I think my next amp will be the JA30. I was thinking cayin 500, but there again its a big fat tube and will not likely present the striking sharp image the 90's produce.
Yep I think the DA30 will serve just fine...headed over one more time to Jadis' home page take a look at her.

Just discovered why Jadis gives many photos of the same amp, shows each with different tubes. You get a choice of at laest 4 types of tubes. UNREAL!.
that seals the deal, I'm skipping the Cayin, going Jadis next amp.
Now has anyone compared the 30 vs the 60? also the DA50?
Anyone know some prices?

Trelja, interesting comments. So there is a difference in the EH 88 tube I had and the stock 88's that Jadis puts in their units? I'm very happy with the 90. After hearing the EK 88 I'd be afraid to try any other tube except the 90.
I believe Jadis offers a variety of tubes for the DA30.
Also hows the DA30 compared to my JOR, a big step up? As the DA60 is out my price range. Though a used one might be a future possibility.
What does rolling the 12ax7 mean?

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.

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.

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.

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?
