I'm planning on investing in a Lyr Amp and it appears there are at least a couple of different Tubes you can order it with. Does the consensus have an opinion as to which Tube is better? Would anyone know the differences between the offerings as it relates to the sound of the Amp?
Here's the blurb I saw on their website:
Lyr ships with either new-production JJ ECC88 tubes or NOS GE 6BZ7 tubes, but feel free to substitute any 6DJ8, 6922, ECC88, 6BZ7, CV2492, CV2493, or 6N1P type tube, new or old, American or Russian or Chinese. The ability to use different tubes lets you tune the overall sound signature of Lyr to your specific preferences.
