My frustrations n my own system seem to have begun when I tried to "upgrade" I was and am again using a Yamaha TSR-7810 after I bought what I thought was going to be an upgrade, a Denon AVR-X4500H that has ended up being a huge pain in general. The 4500 has never worked quite right, and failed soon after I hooked it all up, with what sounded like broken glass mixed in with the surround channels. After it was "fixed", it would let me get pretty much everything adjusted and then would lock up, requiring a hard reset. If I just got it close, it seemed to allow that and ran for weeks without drama, but almost as soon as I did any further tweaking, weird stuff would happen, levels would freeze and a reset was needed and then start over. After a lot of swearing and jaw clenching, I got the Yamaha out and had zero issues as expected. Seems like when I go away from Yamaha, it's not going to end well. A friend bought the Denon, at a smaller than expected loss, and he has had no issues with it so far as he barely adjusted anything on it. He's pretty deaf, so he basically just cranks up the treble. He's actually happy with it! The 7810 feeding an old Onkyo amp for the front L+R channels as it just isn't happy doing it itself. I recently had a power issue (car accident down the road caused all kinds of intermittent power for about a half hour. I was asleep when it started) and my computer UPS shut my PC down, the 7810 wasn't happy with the glitches and..needed a hard reset. Sigh. \n\nA friend of mine has zero experience setting up an audio system, even a 2Ch one is beyond his comfort level, so he asked me to help him. He is using a Marantz 6014 which I believe came from Accessories4Less and it was supposedly a refurb, but seemed new in every way. His new TV is an LG OLED TV and it's making me want one after watching a couple of movies while setting things up. After spending over 12 hours setting things up, he seemed very happy, but both he and his wife have called me, asking me how to do something. They love the sound and pic quality but are very frustrated with the operation of the system. The Harmony remote seems to be part of the problem. It confuses them and they do better with the separate remotes for the AVR and TV. Better, not great. A lot of things seem to be overly complex for most people now. This scanner seems to be past that point, and I scored a two week old one for half price when a friend finally gave up on a 40+ year old hobby:\n\nIt was frustrating for me at first, but now I love it. I have the newer one at home and my older one at work. Sadly, I have other friends who are not happy with it or the handheld that is basically the same radio. One of the big frustrations is that the "Scan by zip code" option scans a ton of stuff that you don't want, requiring you to use the programming software that confuses many people to eliminate a ton of stuff you don't want to hear. They all complain about how easy it was to set up their scanners in the "old days", which weren't all that long ago, as they are talking about P25 radios with PC programming! I have to admit, it was much easier.
