I never could figure out what this website is. I'm almost sure it isn't a private collection ; more like a shop with a deep involvement in producing friend's albums.
Perhaps a (small) concerthall as well - browsing through the non-audio sections, there's a lot of pro gear discussed (Amcron, Behringer, Yamaha etc).
I have a few features in old Stereo Sound issues covering bars or restaurants with-inhouse-djs and/or with-a-place-for-a-band that all used not what you'd expect anybody else doing this to use but ONLY vintage audio gear of the audiophile kind: McIntosh, Altec horns, huge Tannoys, monster EMTs with 929 tonearms etc
I think Freak Beat Freak must be around that somewhere - I don't know but boy! I wish I could pay them a visit!
