Record collector/DJ from Denmark

Hi. I joined the forum because I found some very interesting threads regarding DJ mixers. It seems that I have requirements/wished that are so unique that it's proving to become really difficult finding a mixer to replace my Vestax PMC-55 (with rotary faders) that I am considering to build my own.

I would also like to build a pair of big active speakers at some point, but I think that's a multi-year project...
