Elrog 300B vs Takatsuki 300B tubes

I received my Elrog replacement tubes and I'm listening to them now. It's funny how much I enjoyed the EML XLS while waiting for the Elrogs. The Elrogs raise the holistic/presence factor from the EML's already high standard. Both are wonderfully dynamic and energetic with lively involvement. The Elrogs are more fluid, organic and provide just a bit more sense of 3 dimensional space, you are there factor. Beautiful natural tone!
As I've said before, it's a move from excellent to the sublime. Time and use will determine reliability and longevity merit. It nails the sound quality portion. George of tubesusa.com has been simply terrific during this period wih his service and support. Thank You.
Charles,

Did they actually construct some special Elrogs to match the Franks, or are these the same basic tubes you had last go-round?

According to Elrog my tubes were made to match the Frankenstein's operating parameters for an appropriate match. So we shall see, the sound is sheer organic beauty.
Charles,

MK, Matthais- One of my Elrog 300Bs died today. I am a few weeks out of warranty. What say you?

Charles, one of my tubes died at 6 months and 2 days. I hope I have the kind of customer service you received.
