Richard, I hope you are able to get more information from other users. I’m not sure how much of my comments have helped you. While I have not posted tons on the Holbo, I am totally pleased with the table still, after having my Mk1 now since mid 2018, I cannot say enough good things about it. I have encountered no problems since owning it.
I have not listened to a Mk2, so no idea if there are any real sonic benefits over the Mk1 or not. It seems the new one is more of a refinement of the Mk1. I could be wrong there, either way, either would be a fine analog source! Tim
