” great sounding sub for 12AU7, low noise, sweet sound, great bass”
“like most RCA tubes does everything well, with a good natural timbre and sense of authority through the whole range, while also open and quiet.” Read
” right balance between warmth and detail – not too much of either but enough of both.” Read

Another great tube. Well deserves all the positive comments about it. Great balance of everything without over-exaggeration. Great control of bass and beautiful wide soundstage. Mids are nice and warm, but not overly so. HF is very clear. Not as airy as some other tubes, but the control of bass definitely compensates for it. Great for rock music.
