2019 300B tubes that are worth the money?

I had tried Psavne Acme 300B in my Line Magnetic 508 SET amplifier with good result.

I also have NOS WE 300B which is hard to get with cost of 5K$ or more.

Compared with NOS WE 300B, Acme 300B has clean treble with beautiful tones while NOS WE 300B has slightly tighter bass.


If you like your Cary amplifier, you may try Acme 300B.

I bought my Acme from the linked one.

I also have Sophia carbon plate and Shuguang Treasure 300B.

NOS WE 300B is best with overall sound quality and reliability.

I had run more than 10K hours during last 15 years.

But it still sounds fine.

The problem is it is hard to get good one with reasonable cost.



Acme 300B gives much more refined and transparent sound than either Sophia carbon plate or Shuguang Treasure 300B.

Thus it is worth the money.

1998 production WE 300B turned out to have etched details.


Thus I sold it back after using it for 3 months.

I hope 2019 production WE 300B will turn out better.


I had not have tried other 300B.
