I fall somewhere in between loomisjohnson and kalali…
The Adcom is a fine sounding pre and I certainly don’t believe that a current Parasound or PS will be a significant upgrade, but I do believe that with trying other things you might find a different taste that is pleasing to you. I can see you preferring something else, but the Adcom is a solid performer. Overall, I believe that the Adcom is worth a revamp of a few hundred dollars and I believe that you can get it done for that however, if it came to $1200 for a refresh, I’d be looking at other pre’s myself.
I ran across this link and came back and edited to add this. Even includes a parts list to upgrade your pre, it might be worth doing the upgrade yourself.
