Mr. Tennis,
You asked, "do you think you can configure a stereo system that i prefer, as opposed to a stereo system that i configured for myself?"
Yes, of course. Without a doubt - but I can only do so if you explain what it is that you are looking for. Dealers can not read a client's mind.
You need to communicate with your dealer as you do when you contact a manufacturer or take part in Internet blogs/threads.
An analogy could be made between a hifi dealer and interior designer - the client has their own taste or style but a great designer can incorporate that style to design a room (or system) far beyond that which the homeowner could have on their own.
Yes, I admit it - I watch HGTV with the MRS.
And as with designers, that experience or skill carries an associated cost. Personally, I look at it as money well spent. I do not wish to get something for nothing.
So, rather than playing "hit or miss" via mail order - you should put a knowledgable dealer to work for you. Let them expend their energy - make recommendations - bring over hifi (while you supply the beer and pizza). Make it fun - have a good time - share music with one another.
And, if they do right by you, then give them your business and pay them the retail price (which doesn't even make up for all of their time) because it is the right thing to do. It's a win-win for all parties involved.
I am not the national spokesperson for dealers but I am the type of person that understands that others have skills and knowledge that I do not possess and I routinely hire specialists such as interior designers, professional photographers, web designers, etc.
Actually, my website is another perfect example. I communicated exactly what I wanted and it turned out far better than had I done it myself.
Respectfully,
Burt
