| Sophia Electric KT88 tubes

Dear audiophile friends,
Sophia Electric tubes are my best choice after comparing with all new product tubes on market today, especially on KT88 tubes I bought. After 35 hours burning-in, they sound incredible. I also bought the 12ax7 (driver tube). They totally changed the sound of my system (new McIntosh 275 mark 6). I'm very happy with Sophia tubes.
