Sophia KT88 vs. Psvane KT88

I might be a tad premature here but I was wondering if anyone has any experience with these new Sophia tubes. I only found out about them a few days ago. I did contact the company and was told they do have a limited supply of KT88's. They said this is a new product for them. They quoted me a price of $400.00/pr. Seems quite steep for new production tubes. The Psvane product is less expensive. Any info you have on personal experience with the Sophia tubes, where they are made, how they compare to the Psvane products etc. would be helpful.

You can search TJ Full Music carbon plate KT88 online to see any further feedback. They are from the same factory.

Carbon plate KT88 is hard to make because they tend to be overheated, hence they are expensive.

KT 88's are relatively difficult to manufacture - that's why modern production KT-88's are reputed to be problematic and why there are a lot of bad ones on the market.

The Sophia tubes are manufactured by Full Music in China, yes, but Richard does additional testing to cull out the poorer quality ones. Basically, what you're paying for when you buy a Sophia tube is Richard's testing. I'm not knocking Full Music, as they make most of the best production coming out of China.
