Hi
I am a new member, but seasoned audiophile, 95% listen to analog formats. I discovered classic quadraphonic sound recently, after getting the idea to finally hear my old quad copy of Dark Side of The Moon, which I knew for 40 years it was quad, but never tried it as such. I got a Sansui QRX-5001 (I am a Sansui fan, since then also got the 6001) and was shocked at the level of quality careful quadraphonic setup can provide. I have a new appreciation for all the wonderful sound engineers and producers of the 70's who were producing such high quality recordings, and most of it was unknown to the general public because I guess very few people at the time managed (or bothered) to get a proper quad setup. I listened to a lot of high-end music systems, but nothing had such an impact on me as having heard what a proper quadraphonic setup can do to the spatial immersion into the musical event captured on the record. I also tried Pro Logic/DTS stuff previously, but was never happy with the performance on vinyl (was never designed for that, too low channel separation on records). So, here I am. I am listening to CD-4 as well, and because I have a lot of cartridges and turntables this was one fun experience figuring out what works and what does not.
