Favorite 300B: Sophia vs KR

Sakahara,
You are apparently confusing the Shuguang lower cost/quaility 300b with the more expensive(600.00 USD) ultra quality Shuguang Treasure Series(black glass). I use the black glass 300b and it`s sound is superb, I have about 1700 hours of use with absolutely no reliability issues. As I stated in an earlier post 6 moons has done numerous reviews and comparisions between the premium chinese,high end european and the most recent WE 300b. It would be worth your time to read those in my opinion.

Cheap Chinees, such as TJ's or other's have problems to keep bias at the level, they just don't, so, if I were you, I would buy from trusty source and the high quality only. I have read a lot about 300B's and many of them just dont have the quality level, however they may sound pretty good, but like many already said, if they will be dead in a short time, why bother?
Go for EML's or KR's, but tubular, earlier production type. I own a pair and they are very good.

Very happy with the EML 300b solid plate. Would love to try their mesh.

The problem with EML's Mesh, they cant be used on any 300B amp, bad, very bad, cos I am very interested in them. My amp is Cary CAD 300B SEI.

I ment, ON EVERY 300B amp, sorry guys...
