A Nice Surprise
This tube replaces the stock Sovtek 5AR4 in my ModWright LS100. I'm only just beginning to appreciate the effect rectifiers have on sound quality. With this tube the sound is smoother and more relaxed. The sound stage is moved back somewhat. But the real surprise is that individual instruments seem to stand up when played and then sit down again when the player is done. This effect just adds more dimension and realism to high definition recordings. Can't comment yet on reliability, but the sound quality is a notable step up.
