It’s that synergy that has me wonder about a high end integrated vs what I have.
Well that’s just a total non starter. If you can’t be more specific about what specific improvements you’re looking for, even people who happen to own your pre and amp will have absolutely no idea of which directions you’re looking to go. In short, this is a total crapshoot because nobody knows where you’re aiming and we don’t have crystal balls here. I could throw out manufacturers like Gryphon, Vitus, etc. but it means nothing because I’ve absolutely no idea what you’re looking for. Do you understand how this is an utter waste of time for anyone who actually cares and wants to put some thought into making a meaningful recommendation here? I wish you luck, but short of you being able to provide at least any idea of what you’re looking for besides just “synergy” this is just a total shot in the dark and an utter waste of time.
