I would like to find a modern device that decodes an analog quadraphonic signal from old source equipment (8-track, phono, etc.) and sends it into my modern receiver through the multichannel analog audio inputs so that I get the correct soundstage. Now then, I may be naive in thinking that my receiver's logic won't try to redistribute the input according to a modern multichannel algorithm, so tell me if I'm barking up the wrong tree. I'm currently using a Sony STR-DA1000ES (not so modern anymore, I know), but I will upgrade eventually. When I upgrade, I plan to transition to a fully separate system with independent preamps/source selectors, signal processors, and amps. So perhaps there is a component signal processor that includes quad decoding alongside DTS, Dolby, etc.?
I'm surprised I couldn't find anything in my web searches. All I see is vintage gear, which I don't want. One would think this is not a difficult device to engineer and build. Perhaps the only people who listen to old quad media are also vintage hi-fi junkies, and my desire is anathema to the whole scene; while the users of modern gear just buy rereleased/remastered quad albums on CD?
I know about the various quad encoding formats, so I don't suppose it is too much to ask for this magical device to be capable of handling most (if not all) of them? I don't expect it to be able to autodetect the format; I'm okay with setting a switch on the device to tell it which format the recording uses.
If no one knows of such a preamp/decoder, could you at least give me some search tips or links to sites that would point me in the right direction? I searched the forums at www.quadraphonicquad.com
, but I haven't created an account there yet because I get the vibe that those folks are pretty staunchly in the vintage-gear-or-die camp.
