Matched pair for $1500... Sure makes me glad I got out of the 300B amp game. In fact, looking around at NOS prices for 6922, EL34, 6SN7, etc, I am glad there are very viable non-tube alternatives out there these days
I guess I jinx'd myself for saying such a thing since I bought another 300B tube amp and a bunch of 300B tubes.
It's always interesting to read other people's preferences on certain tubes' sound.
For me, it's about what combination of tubes I can string together to arrive at a final sound I want. For example, I can string together certain 12AU7->12AX7->300B combo's from my boxes of tubes to reach what I seek, and in Elekit 300B amp, I can get closer to a sound signature I want with Genalex 300B tube than Takatsuki 300B. Then again, I haven't tried all the dozens of possible combo's with Takatsuki, which will take weeks, so other people may have different results, etc...
