Jeff Day's Review for Positive Feedback Online:

"I was impressed with how superbly the Sophia Electric EL34-ST expressed the musicality of music and musicians, with tone, timbre, tempos, dynamics, harmonies, melodies, rhythms, and the exciting interplay of musicians playing music together as one, being so emotionally involving I found it truly hard to put into words.

"The Sophia Electric EL34-ST presented the music making of this session with aplomb, and I was completely mesmerized by NAS as he sang "On the Road Again". The dynamics were superb, as were the timbre of all the instruments, and the way the beat was presented gave the desired visceral reaction making me want to get up and dance to the music!

"I kept marveling at the extremely natural tone and timbre of the musicians and instruments, the incredible emotive effect that the Sophia's relayed from the music, and I really couldn't find anything to fault.

"Compared to the Sophia Electric EL34-ST the timbre of the Winged "C" EL34 sounded leaned out and unrefined, and their overall tone was wanting. The Winged "C" EL34's dynamics sounded compressed in comparison, making beat less pronounced and involving, and there was less dynamic nuance apparent, which robbed melodies of life in comparison to the EL34-ST. The Winged "C" EL34 vacuum tubes were also less resolving, and missed a lot of nuance and subtle textures that can make music so exciting to listen to.

"The performance gulf between the Sophia Electric EL34-ST and Winged "C" EL34 was rather dramatic, and that is that. I couldn't wait to get the Winged "C" EL34 out of the Leben CS-600 and put the Sophia Electric EL34-ST back in.

"The Sophia Electric EL34-ST are simply the finest vacuum tubes I've ever had the pleasure to experience in my Leben CS-600 integrated amplifier. They are remarkably musically satisfying, full of emotional impact and excitement, are very refined and articulate, tonally gorgeous, with an effortlessly beautiful and satisfying overall presentation that allowed me to get caught up in the music and forget about everything else.

"The Sophia Electric EL34-ST are expensive compared to Winged "C" EL34, but in the case of the Sophia Electric EL34-ST you definitely get what you pay for.

"I really don't have enough superlatives to describe how impressively the Sophia Electric EL34-ST performed in my Leben CS-600 when playing the American Epic sessions, they are truly sexy blue bottles full of musical magic!

"Highly recommended!" -- Jeff Day

User Feedback:

I just wanted to follow up on the Sophia Electric EL34 tubes I got for the Sophia Electric 126S amp. I am not quite at 100 hours – maybe 70 or so- but I have to say they are unlike any other EL34 tubes I have used. The bottom line is the music is just there. There is a naturalness and musicality that I would normally attribute to a change in amplifiers or speakers but not tubes. I feel like I am just hearing the music as it was recorded without any additional artifacts or colorations. Your el34 tubes in your 126-03 amp are deeply satisfying. I have been chasing after the “absolute sound” for over 30 years. Your amp and tubes have stopped me in my tracks. I am a very happy music lover. Thanks you so much for these wonderfully musical products.

Thanks,

Jim, DC
