Hey Danlib; all of the above and add Speaker designer;
Don't sell to 'goners typically, but I worked and sold Revel for years and Levinson and Rotel, Gallo etc.
You could say i'm an authority on this subject, just a little bit. :)
My special interest is multi-channel systems and how to design and set them up.
I am able to sell ATC speakers, due to a unique relationship with the importer. Often I help other dealers sell their ATC's too. Powered speakers require considerable education of the client.
Revel's center channels for some reason do not blend with their counterpart tower/bookshelf speakers. Their is an issue with the crossovers, amplitude measurements don't reveal the problem but they will NOT blend together. Couldn't figure it out and tried for weeks, made phone calls etc. They just don't work.
That's the problem with Revel.
As for the comment about multi-million dollar homes with Denon and Deftech, that is not the fault of the owners often its the fault of the audio designers who would rather program remotes and sell flat screens than get a grip on what good audio is. Look it up, often the companies who did the install only sell brands like Denon and Deftech.
HT theater people want good sound, infact audiophiles are the goofy ones who want weird stuff. Like horns in a small living room and 3 watt circa 1916 amplifiers. So I think the generality is pointed the wrong way. Quality clients want the best value for their money all the time. Insulting them by assuming they are ignorant is the wrong attitude for you to succeed. Audiophilia is a curable disease if the victim wants to be cured. Do not cater to audiophiles just be prepared for them.
BTW Eclipse now your getting somewhere with your speaker choices, a much better variety too of good better best, & fancy boy. Do not underestimate how good a receiver based system can be. The Miata is a fine sports car and lots of fun, if you get my drift. As the desinger you must be able to maximize your gear and be focused on what you do well, so that you do it well. You will need an installation team, no way around it. You sell luxury products, would you want to glue the diamond on your fiances ring?
BTW most audio stores have 100IQ dudes, so if you have brain and apply common business sense and a scientific method, you can eat their lunch all day.
I don't compromise for my clients and neither should you. Just don't expect them to drink Kool Aid for you. People with $20K to spend didn't get wealthy by being an idiot.
