I just love the sound of the Genalex 300Bs. I haven't compared many in my amp only the PS Vane "mesh" perforated plate tubes and there is a pretty big difference between the two. The genalex sound better across the whole range IMO. Much more bass and better bass. The sound is fuller. Not as brittle as the PS vanes. I had a heater fail on one of my genalex tubes and so I was without them for several months. Today a new tube arrived for my Genalex pair and I haven't stopped listening since it got here... even with uneven age of tubes it still sounds fantastic. I wasn't going to not use a $150 tube just because its a little older than the other one.
