Vintagehifi.dk Meetup 2019

Each year the forum at Vintagehifi.dk hosts it’s yearly vintagehifi meet up. Vintagehifi.dk is the primary danish forum for all things related to vintagehifi. I joined the forum right at the beginning back in 2010, and since then I’ve tried to get to the meet up, usually planned sometime in march.

We shift around the country, to make the gathering available to more members, and it is always a pleasure to attend and meet new and old friends. Listening, seeing, learning and in all respects just geek out over old gear. This year we held the gathering right outside Copenhagen, and I was asked to present my speakers and setup.
