Sonic Frontier power 2 6922 tube swapping


Would there be any advantage in replacing the Siemens 6922 tubes with Amperex PQ white label tubes in my Sonic Frontier power 2 amp? The unit has the Siemens tubes that Chris recommends with the SE update.

You would be sure which you liked better!! You might like Amperex with 6550's and the Siemans with KT-88"s. The possibilities are what make tube rolling enjoyable albeit expensive.
SF is always a different animal that is a known tube eater.Often it is a matter of what will survive. The Amperex is a sweeter airy tube but the Siemens has great extension and a undistorted clear strong signal that make it a holy grail.
