Have you considered the Emission Labs 5U4G Mesh? They make a great tube. They aren't inexpensive but are spectacular. Even compared to Sophia. Sophia's 274B are $160 to $175 each where the EML 5U4G or 274B are $320 Each.
I just set up my EML page yesterday but Art Audio uses several of their power tubes in some of our new products (Elise and Adagio) and as I have been talking to them and I spent a day digging through and learning about their products, the are committed to producing exceptional products.
Just a thought. You can check them out here.
