People have asked, "which brand of 7199 is the best?" As with most things "Hi-Fi", it's not a clear-cut answer. Here's how *I* rate these tubes.
Generally speaking, the RCA's have the lowest distortion, and would be my first choice. The Sylvania's come in second. But the Sylvania's are a *slightly* quieter tube than the RCA's. If you are looking for the quietest 7199's, go with the Sylvania's. Either brand will make you smile! There is nothing at all wrong with the GE's. They are very close to the RCA's and the Sylvania's, but I would still place them in third place. ANY of these 7199's will simply blow Sovtek's out of the water! (It's not even CLOSE!)
At $50.00 a pair (including shipping in the US), this is simply a deal you don't want to miss. While I DO have good stock right now, that will not always be the case. Prices are rising elsewhere. My price is not! Just remember, when my stock is gone, I won't be getting any more in. I am liquidating 90% of my tube and parts collection. When that's done, it's all over! There won't be more.
Let me know if I can be of service to you.
Sincerely,
Bill Thomas
