BAT NOS Super Tubes

Hello Bostonbean,

The way I hear it is the BAT NOS tubes are more dynamic linear so dynamic shading is more nuanced and energetic. I also hear a more textured tonal palette with the BAT 6h30's.

That being said the new production 6h30 has got quite a bit better over the years and IMO their sound has improved nicely.

Only you can decide for yourself if it's worth the extra $$$ to go for BAT NOS tubes. The right answer for you will be a different one than it will be for someone else.

There is quite a bit of discussion on the topic if you do a search here on A'gon and Audio Asylum.

best,
Tom

I just wanted to add that in my experience I've found the 6H30DR's contribution to the sound is much more pronounced in the BAT preamp(s) then in their amps.
