I finally replaced my everyday listening tube the Genalex Gold Lion, with a NOS EDISWAN CV 2492 tube. I am quite happy with this tube. My HE 1000's sound superb from the Liquid Crimson, with the Ediswan CV 2492 NOS tube. The bass has more impact and slam to it, without sounding bloated. The bass, in Frank Zappa's Republicans , has more thud, which makes the track come ominously alive. Likewise the mids are sweeter yet remain ever so transparent and natural sounding. Dave Brubeck's Take Five, from his Time Out Album, the mids are sweet as honey, but none of the detail and natural transparency is lost. The result is this track just sounds devine, feel like I am in smokey jazz club, sipping scotch, grooving to the intoxicating sound. The treble is spot on without too much sparkle or fatiguing sybilance. I really like hearing Patric Doyle's Henry V ( the soundtrack), and I never detected any annoying sybilance. I have new respect and admiration for Liquid Crimson and it will always remain in my stable of amps.
