I'm fortunate enough to live in NY where there still exist a small number of "bricks and mortar " shops. The one that is most like the old days is Stereo Exchange in the city - walk right in, look around, listen, and they probably have it in stock to carry out. Pretty amazing considering the capital investment required to fund that sort of inventory these, or in those days.
I keep my audio and video interests apart. I appreciate the picture quality that today's flat screens offer, but I've found surround sound to be more annoying than enticing. I have to admit that I haven't bothered to purchase a true audiophile surround system, but I've never found it justifiable. On the other hand, I'm still chasing the two channel audio dragon going on 33 years now and I still enjoy it.
