Re: Phono Transfer System Construction Information

Sample Soundfiles From the Stone's "Sympathy for the Devil" Focus on the piano chords in the first 15 seconds. For whatever reason, after 15 seconds the mono compatibility of the part changes.

Re: The Studer "90° Filter" Stereo to Mono Summer/Recorrelator
