Jadis 6550? (for CJ Prem. 12)

trelja--according to one of the dealers here, the jadis tubes are chinese made. you're right, i've got a bit more investigating to do. i have not yet heard them and the local hk dealers are not too familiar with the "let me borrow a broken in set of 8" routine. they're said to be warmer than the svetlana 6550c's that i'm using. i guess i take some comfort in the fact that jadis uses ei kt90's (which i've used on again and off again in my system).

i'm willing to bet you're right(aphile); it would not surprise me at all to learn that the jadis 6550's are not chinese. this is part of a little game that i play with some of my local audio dealers (and dealers of other luxury items, for that matter). the gleefully provide me with mis-information and i either call them on it on the spot or go out and do some research and come back and call them on it. for the most part, i'm pretty well hated. ah well, the only real shame comes at times like this, when i mistakenly pass along this mis-info. i think i'll visit this guy again and see what he has to say for himself...trelja--i agree that the kt90's are more powerful, better on the bottom end provide overall better balanced sound. i was using the ei's for a while. about 3-4 months ago i switched the interconnects joining my cd player and amps, from mid-range transparents to kimber's kcag. when i made that switch, i fiddled with the tubes a bit and determined that i liked the warmth of the 6550's better with the silver cables. i still have the ei's and i really do owe it to myself to to a bit more testing before i invest in new 6550's. i have not listened to kt88's.

trelja--i'm running pretty efficient speakers, jm labs' mezzo utopias. cj actually offers a el34-based premier 12, the 12xs. they have roughly half the power of the 6550-based models. unfortunately, i cannot use my 12's with el34's without sending them back to cj for a bit of reworking. i really enjoy the el34 sound. in fact, my first tube amp was cj's mv55, which uses 2 el34's per side. i would have entertained the 12xs when i bought my 12's (my mezzos would run nicely from either), however, i was buying used and a good deal came up on a pair of standard 12's. i'm pretty happy. i'd be interested to hear the homegrown cables. i'm also pretty happy with my kcag's. but when i move back to new york later this year, i expect i'll need a longer run of interconnects. and the kcag's get really expensive as they get longer.
