Favorite 300B: Sophia vs KR

Hi,
Sakahara, you did`nt offend me at all. I was just trying to be helpful and let you know they`re significant differences between the low cost vs high cost chinese tubes these days and that they compete with the higher quaility europeans. By the way your system must sound fantastic with that Tron amp and Horning speakers. I really like my Coincident speakers but would also love to hear your speaker and the Tonian Lab Classic 12.1 with that PHY-HP 12inch driver.
Best of luck

Who sells the Shuguang Treasure Series? Is there a manufacturer website? And what about the Genelax Gold Lion PX300B?

Is Shuguang Treasure Grade B ok? Reading the description they sound defective. $395 from Grant Fidelity. $510 for Grade A.

My interest in this tube is growing as I'm not feeling Sophia at the moment (failed 274B) and would like to give another brand a try.

EAT is too expensive. KR WE Clone is available for just over $500, but I don't want to be disappointed if it fails and lose $$. And the EML 300B is $493. I'm not paying any more then that for these tubes. I'd rather pick up half used NOS WE.

I purchased the grade A versions from Grant Fidelity

The Grade B Shuguang tubes aren't defective. They're just a lower quality tube. Shuguang matches each pair, and the tolerance differences determine which tubes will be Grade A, B, etc. I also use the Shuguang Black Bottle 300B Treasure tubes, and have had no issues with them, and they sound very good. Very clean and clear, with pretty decent bass for a 300B.

I know Grant Fidelity has the Treasure tubes. I think others do, too. The only exclusivity Grant has with tube distribution, I believe, is with the Shuguang Psvane 845.

You can find them cheaper than 600/pr, but beware. You may not be getting Grade A. If you go with Shuguang, buy from a North American retailer. Shuguang routinely exports their best tubes, and keep the lesser quality ones in China/Asia. So, if you go looking on ebay or something like that, and find a pair for 200 bucks, don't think for a second that you're getting a great deal from the guy in Shanghai.
