6550 or KT88 ?

Just this last year I bought a Music Reference RM-200 tube
amp. The amp came with two sets of KT-88, both RAM lab tested. While they sounded pretty decent, I had a feeling
I could do better. I bought a new quad of Tung Sol reissue
6550's.....OH MY GOD! I am now convinced I am DONE, the 6550's are just that good. It just seems everything is there, be it slam, liquidity, air, you name it. Maybe I just hit in the perfect match for the RM-200, but let me tell you the KT-88's are never going back in; they sounded congested and smeary when compared to the 6550's.
I could NOT be happier.
Your mileage may vary....but luckily I am getting 100mpg.
By the way, a "matched" quad of 6550's was $105!

Here you go.....here is a current Ebay Buy-It-NOW from the seller I went thru :

4 Matched Tung-Sol 6550 Reissue tubes,NEW
Item number: 5855636196 Buy It Now price: US $103.38

Shipping is $6 bucks. I got mine in ONE day priority mail.
This guy (Jason) is VERY good...I have bought from him three or four times, very trustworthy, always prompt, good product.

Good Luck!....best money I ever spent. Hey, if you don't
want the 6550's, drop me a line & I'll take 'em as a backup.
My guess is you won't want to, tho!
