Isn't crazy how things come full circle. I can remember in the mid to late 70's when I was a young man in my 20's how I was so excited to go down to the local Radio Shack and purchase a quad turntable, receiver, & 4 speakers. I had just a few quad vinyl albums: Ten Years After, Doobie Bros. , etc. Now here we are as a group almost 50 years after I first experienced quad that we are getting back into quad, 5.1, and dolby atmos. With every quadio batch release I relive that excitement I had back in my 20's!
