Difference between KT88 EAT and NOS in Jadis

No "long term personal experience"(sorry to say). My recent past financial state(expensive divorce) had precluded that possibility. Thus- I can't say anything concrete concerning their reliability, but they do carry a warranty. It's been my experience, that if tubes make it for six months; they'll last the long haul. Things are starting to look better for me this year, and I'm giving an octet of EAT's tubes some serious consideration myself. The Winged 'C' 6550's I've got in my monoblocks right now probably have 6 months or so left in them. The taste that I've had of the EATs makes me want the whole burrito, and I've seen them on sale for around $1300 a matched quad!

Let me know how they sound, I won't be buying them at $325.00 each regardless of warranty. I pay high for 10,000 hour tubes but KT88 and 6550 are not in that category, at least not in VTL 750s or CATs.

Maybe if a quad would serve my whole system the price would not look so bad. Since I have two pair of 750s the total for a single fitting of EAT would be $15,600.00.

I use an Octet of selected Gold lion reissues in a DA-60. I bought them from Jim Mcshane over on AA tubes asylum classified. These tubes took me by surprise. I told him wht I wanted them to do. He gave a single answer this is it nothing else will be what I like or he likes for that matter. They are simply superb all around, fantastic!
They are expensive for current production but nothing like the EAT. I really don't believe that you can acquire a truly matched octet of never been used 1960s even 70s KT-88s, unless a private collector is willing to part with them. The price I couldn't even guess but the amount will never be printed that is for sure.

I used some kt 88( almost all kind), and in my amplifier ( audioaero ) kt 88 gold lion reissues, is better than kt88 EAT tubes, both are the best in production, but I think gold lion is more transparent . I think i very expensive th EAT tubes .

My audio cohort bought a quad of Gold Lions for his Cary Rocket 88. Absolutely wonderful sounding tubes.
