Mello I'm interested to know your source for old tracks. Do you encode them straiht form vinyl, do you buy them somewhere in particular you could recommend ?
i just rip the tracks i need straight from my collection of vinyls there is actually a company here in hamburg, wich offers a service on purchasing mp3 and encoding vinyls as a service, didn´t check it out yet but seems to be ok.
great sample source, too!
