Charles I share my enthusiasm and whatever knowledge I might if someone is interested but I hesitate to recommend them just because I like them. I think we differ a bit there perhaps.
Reason being they are totally different than what most are used to hearing. A totally different flavor of sound that usually takes time to get used to before falling in love although with a lot of familiar and tasty ingrdients of good sound to offer right out of the gate.
Also those who use radial or omnidirectional speakers are a minority so they are clearly not for everyone otherwise the reverse would be true.
If one is game to try than I am all in. But I probably more often than not tend to recommend more mainstream options for most unless there is some good reason to encourage them to try something radically different, like a history of failure with another approach.
There is the in home audition period and guarantee as an insurance policy so that helps.
Whereas with amps, what I recommend will largely be determined by what speakers will be used. If one wants to start with an amp and build form there, that’s one perfectly fine way to go about it though I would argue start with speaker/room integration because that matters perhaps more than anything and one usually has limited ability to change the sound of their room. Different speaker design, no single one or type will tend to work best in different rooms. That’s pretty much a given. Also choice of amp will determine what speakers are a good match and some choices, like choosing a limited power amp, will likely limit speaker choices most.
My job is to deliver computer based solutions (not audio though I cut my teeth in and sold audio and home electronics for a brief period in college many years ago)) and that means being solution centric and largely technology agnostic and that’s pretty much the way I roll.
I think it started when I worked for Radio Shack first as a salesman and later briefly as a store manager. We were taught that when someone walked in the store they had some problem (like a blown tube or fuse) or were looking for something (like a particular hifi) and our job was to figure out what and solve their problem and then make a sale. Good advice!
