So true. I many time peruse Audiogon, US Audiomart, Hifi Shark etc to just see what is out there. Then I go onto forums and online reviews and start developing an opinion. If I get more interested I call friends who may have had it, like Joe. Hes had everything.. I also read manufacture websites. If it's reasonably priced new, I may call a dealer. If I go that route, I usually buy it new. My preamp, all digital and phono gear as well as cables are all new. One set of speakers is new and one used. One set of amps is new and one used.Audiogon delivers more options, on more gear than anyone I am aware of.
You can find several versions on what your looking for in one place.
In all honesty I usually don't buy used anymore. Its so often others garbage. If I am leaning towards used, I prefer a dealer add. I just feel there reputation lends them selling what they know is solid. I took a shot recently on used amps from a member here and once again got a burned out failing amp. It's such a heart ache and headache to deal with. I'm way to honest to dump it on someone else.
The Brick and Mortar near me. It's just not me. Not what I want. Now with Covid I can't even do trips to San Francisco, Portland, Vancouver where I can combine fun and viewing. But to others points about stores, I was in San Fran a couple years ago and wanted to see the YG. I was pretty much brushed off and told to take a hike. Don't bother coming around. Same with a call to a store 6 months ago. Guy said whats my budget, I said maybe $5k. He said he was busy and hung up.
I can say this about many audio dealers I have met. I am very turned off talking with them. They ask what you have, then dive into explaining why what you bought is "S#!t" and you wastes your money. Way to many audio dealers are trash talking fools. I am so turned off by trash talk. As for me, it has probably killed a few deals where I would have pursued the gear further and maybe bought it, if it were not for the rudity of the verbal exchange.
In closing, although almost everything I have is new, not a single piece was bought from B&M. All direct or online distributors.
