With continued listening to my replacement Elrogs ER 300b I've come to realize they sound "better" than my original pair. I don't know if better matching of the tubes to my amplifier's operational points is the reason or not. The natural sound and music reproduction is the best I've heard in my home to this point. "If" the tube durability can match the sublime SQ, this is the best tube recommendation I can offer someone. This tube is really something special.
