These two tubes are both excellent but very, very different. The Amperex is a smooth, detailed, holographic sounding tube. The Amperex makes you feel surrounded and immersed in the sound and it is well balanced. It is ultimately a more laid-back sound that I think appeals to many. The Genalex is also very detailed and the sound stage is wide and natural sounding but it is not quite as "holographic" as the Amperex. This idea is hard to explain unless you hear it. The Genalex has nice punchy bass and is a generally intimate, forward sound. Think of it this way: The Genalex is like standing dead center front row of a concert with all of the beautiful details smashing into you while the Amperex is like sitting a few rows back and having an orchestra of sounds surrounding you. I'm not sure exactly which tube is specifically best for electronic and trance music. I can say that I definitely enjoy how Purity Ring sounds on the Genalex and that I haven't owned the Amperex in a while so I can't compare it directly.
Interesting comparison! Now I want to try the Genalex to compare it with my Amperex.
