There’s a little bit of an elephant in the room I believe. You are much more likely to be able to adjust your soundstage and imaging with different speakers than any kind of preamp changes. Possibly you just love your PBN’s so now you gotta find what works with them . I think if you changed speakers you might find that is the path to you desired sound
going from tube preamp to solid state
just toying around with this and it might not even happen.
have a tube preamp now and while i might sell this later on and get another preamp.......have there been members that have had a tube preamp, sold it and went to a solid state preamp and kept it ? or did you prefer the tube preamp sound and went back to it ?
maybe got a tube preamp that uses different tubes than the previous one did ?
the preamp i have now, i like the way it sounds, but just not a fan of the 6sn7 and never really have been. i prefer the 6922, 12au7 / 12ax7 tubes better.
