I was reading up on some post-Smile era Beach Boys albums and came across the following paragraph from the Wikipedia entry for the "Surf's Up" album: "This LP was mixed for Quadraphonic reproduction (also compatible for Stereo). It was to be played back by using the long extinct Dynaco or EV Stereo-4 decoders. However, this recording (LP or CD) can be played back in Quad by most of today's audio-video receivers. The surround sound information can be extracted using the Dolby Pro Logic setting. The Carl and the Passions LP and some of the songs on the Sunflower LP were also mixed with this process." Has anyone ever tried this before? If so, is it the equivalent of actually playing the discrete Quad LP of "Surf's Up"? I would love to here the original Quad mix of this release but am a little skeptical of the Wikipedia info.
