I recently found a brick and mortar store locally named The Stereo Shoppe. They have a handful of stereo demo areas set up, but they also have a dedicated Atmos room, and I was wowed by the sound in it. Raymond, the proprietor, has been working with me to upgrade my surround system. He sold my my Marantz 7706 pre-pro at a sale price, and he is setting up a new turntable with a CD-4 compatible cartridge and stylus. So just because the word “stereo” is part of the name, that doesn’t necessarily mean they reject 3-12 channel systems.
Now, if he would just carry Involve Audio products…
