I'm a new member. I've been into quad since 1976 when I bought the Marantz quad receiver along with SQ and CD4. Since then I've built up a collection of quad reels, dts discs, and then dvd/dvd-a/sacd/blu-ray and now use an Oppo to stream flac/dsf files from a hard drive. All great. Visitors love using the Marantz remote control to quickly isolate different speakers. My buddy in town has always encouraged me to join so I finally have, now that I'm retired.
