quote: "Sophia Electric tubes are being made and tested by US audiophile quality standard. Sophia Electric engineers are monitoring each every pairs of tubes being sold with a complete quality control system and book keeping.
Sophia Electric design and refine each new tube model before put into production. Only the best of the production would qualify for Sophia Electric's high standard.
Those think they could just get tubes from another channel with the same quality of Sophia Electric, they would get burned soon or later."
I think it worth every penny for Sophia Electric tubes. The Chinese factory quality control was not there nor sound like there is. If the factory wish to sell every pair made, and with a small discount to the Sophia Electric's premium price, will you(the US audiophile) buy it?
