Favorite 300B: Sophia vs KR

Afc: Don't take offense. I was being facetious about the Shuguang Treasure Grade B being defective. I realize they're not. But the way the description is worded it comes off that way.
What other 300B's ave you listened to? Have you heard vintage NOS WE? And thanks for the buying tips.

At this point I'm leaning toward either EML or Shuguang Treasure.

300B comments from tube gear designer;

"I supply my new amps with basic/standard 300B's (Chinese/Russian) as I know customers will want to change them in the future. I only offer Emission Labs tubes as a priced option. On the top end gear I use Emission Labs - they might not be the best sounding but they are very robust, are extremely reliable, also sound very good and they look good too..... I have not heard the carbon plate or Shuguang Treasure as they do not look like a 300B and are only clones - These should really be called by a new name and not a 300B because they are not a 300B. Also I don't like using anything from China. "

Sakahara, no worries, none taken. Haven't heard NOS Western Electrics. Very expensive, and a lot of people are trying to pass off the newer WE 300B's as NOS. Saw a pair the other day- made in 1998- for 4000 bucks. Ridiculous.

sakahara,
The statement from the tube amp designer sure makes him seem misinformed and ignorant, Such strong opinions on tubes he has`nt heard and sweeping stereotypes regarding chinese products, so everything produced in china is bad? I hope his amps are better thoughout than his foolish conclusions regarding 300b tubes. There are numerous posts on this site by 300b amp owners of many different brands who have been very pleased with the better quaility chinese tubes from Shuguang, TJ Full Music Sophia etc.

Who has the best price for EML 300B?
