I'm looking at tube rolling and am currently running Electro-Harmonics EH-6550 tubes. They sound great, but I don't have any reference to that. I would like to listen to other tubes for any difference of quality, control, tones and or sound stage.
Any comments on other 6550 tubes characteristics, sound definition etc, would be appreciated. I mainly listening to jazz and classical on 385 Tannoys.
Thanks.
