Best 300B tube


Hi! I have an Audion Silver Night MKII with Tannoy Turnberry SE and a Chord 2Qute connected to a Macbook Pro with Audirvana 3.5. The Audion mounts JJ 300B tubes. I replaced with TJ Full Music Solid Plate matched pair. The middle and highs expanded, all very clear, but the sound now it's so bright that a in less than an hour a get auditive fatigue. So I got back to the JJs, thinking what's next. Gold Lion or it would be similar? Raise money for KR Audio or stop curiosity and just conform with JJs, that are not bad of course? Thanks a lot.

Dave...do you see a large incremental improvement if you add the EVO to the Lumin X-1?  As you know I did not hear any improvement with the EMM LAb DAC and Laufer MP.

Sorry to the OP for being off topic.  

I do have 16 300B Golden Lion Tubes in my Canary Audio Grand Reference 2 mono amps. 

Count me in the "don’t overlook your driver tube" camp.

300Bs (and directly heated triodes in general) are very responsive to the driver, and what worked with your JJs may be the wrong driver for the TJs (or other higher resolution 300Bs).

Just because they’re Mullards, doesn’t give them a free pass for all applications.
