Ratings & Reviews
I replaced these tubes in my Atma-Sphere Music Preamplifier 3 (MP-3) and I couldn't believe how different than original (made in China, no brand name) these tubes sounded. The sound described on these pages as neutral is very true. These tubes have very linear and not "tubey" , more like solid state sound with clarity in all frequency spectrum. The bass is very tight and a little dry sounding but this complements soft and bloomy bass (read bloomy and heavy) recordings.
Update: My comment from 6/5/14 about the a little dry bass was based on the wrong assumption as my speakers placement was far beyond optimal due to furniture rearrangement and the tubes needed few days to settle.. Now the bass is tight and extended with no hint of dryness.
