| Sophia Electric Princess 274B mesh plate tubes with Woo Audio Headphone Amplifier
Received date: March 8, 2016The Sophia Princess 274B rectifier is truly a piece of art. In comparison to my old tubes, the Sophia Princess tubes presented me the same piece of music in a much more delicate and musical way. The sound is richer and more detailed; the trebles extend much further out and higher up, the music sounds substantially more open, and it feels like the vast soundstage of my HD800 has been completely filled up even to the furthest extent. What makes the tube even better is its price – It is only at 160$, a number that is well worth the improvements it will bring you. I highly recommend anyone who’s considering the Sophia Princess 274B tube to give it a try, and for those who already own it, the 6SN7 driver tubes will be another valuable upgrade to consider.
