6550 vs KT88 vs KT90

The "Electronic industry" (Ei), has been rebuilt, however, the economic "sanctions" are still in place, and who knows how long? I may be able to get some KT-90, and other Ei products. E-mail me with the questions if interested!

Thanks for the offer Eldragon! Ei tubes are available. In fact, Jadis informed me that they see no potential problems with supply. However, the sanctions will probably hurt us in the USA. No one will care because this is such a minuscule hobby. But, last year the price of a matched quad of KT90s was $96(in a Stereophile ad), within 2 months it went to $150. I am not sure where it is now, but buying from a high end dealer or Jadis will be over $500(as of February, 2000). I am just happy they supposedly last way longer than we usually expect tubes to last.

Trelja; thanks much for the specific info. on the big amp tubes. Jordan, it was particularly good to hear your comparison of the DNA-2 with some good tube amps-- and glad to hear that tubes can be competitive in the bass. Thanks, and Cheers. Craig.

Trelja i guess you like your Jadis...? How detailed they are? I heard, earlier models had somewhat "sloppy" bottom? Regards!

Eldragon, I really love the Jadis. I have listened to many a product out there, and have EXTENSIVE experience with three in particular(Audio Research, Jolida, and Rogue). And, to me, the Jadis was a clear choice. I am somewhat surprised to hear the bass comments, because even when I had NO interest in buying a Jadis(late 80s - early 90s), the great bass(compared to other tube amps) was one of their main draws. I feel the bass is very good. Up there with any tube amp using 4 output tubes(can't compare to some of those BIG monsters using 16 or 32 tubes, obviously). And certainly, the best of ANY real world tube integrated. I believe it is a product of their massive transformers, large capacitance, and the KT90 tubes. It also has tone controls, so you CAN jack up the bass a bit, if ever needed. The amp is as detailed as I have been around. I hear things in music I have never heard before. CDs I have listened to hundreds(on various equipment) of times reveal new information. I am always amazed at cymbals, in particular. They are rendered with SUCH crispness, I always wonder why I haven't heard before. The detail may be a product of the passive preamp section. I like the combination of a passive preamp section into a tube integrated. The C - J CAV50 also does well using this combination. But, the Jadis is a MUCH better product. My main complaint with the C - J is its lack of power. Others complain about it being OVERLY warm, but I find that endearing of the C - J EL34 based amps. I imagine the Jadis could become quite warm with the Svetlana EL34s, if you are into that sound(I've yet to try).
