: \r\xe2\x80\x9cThe 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.
Highly recommended!\xe2\x80\x9d '
