McCormack dna-1 upgrade or no

Sorry, I don't remember. It was 20 years ago.

McCormack audio is now part or wholly owned by Conrad Johnson. 
I put the money in a newer amp.  

I upgraded my DNA--1 up to the gold rev, but didn't commit to that upgrade. I had the pleasure of talking to Steve about each of the upgrades we did. That was about 15 years ago. I got curious about some other amps especially tubes. Yes, I dragged my amps to other peoples home and we compared them. Anyway, after doing a number of A/B comparisons in peoples homes, I sold the McCormacks, I couldn't see spending more money and not being sure that when finished they would be comparable or better to what I had heard.  Just my two cents. Good luck

$2500 for an upgrade?  I have to start raising my prices  we build a complete Point-to-point wired hybrid power amp from old Counterpoint chassis for $4K.  Intersesting.

I've been mulling the upgrade path as well. I have a DNA-1 in excellent condition. Original owner. I think the amp is about 30 years old right now. Been looking to the basic upgrade from Steve, without the new base, but adding a new transformer. It's about a $2700 upgrade. Was weighing that against a selling the DNA-1 and getting a used Bryston 3b squared or 2.5b squared...
