"But here's the dilemma. How often can one fairly audition speakers, amps and other gear given the paucity of high end B&M stores? Forget being able to control all the variables, like using the same model amp when comparing speakers. At least in my neck of the woods, forget taking gear home. Doesn't happen."
I agree that you can't control all of the variables. The good news is you don't always have to. I'll use myself as an example. I'm very picky when it comes to high frequencies. If a system can't get hf's right, I can't listen to it. I don't find it too difficult to judge components in this area under less than ideal circumstances, like a dealer. Given the fact that hf's are very directional, room acoustics don't factor too much into the equation, at least for me. As long as there's nothing in the way between myself and the tweeter, I can usually pick out what I need to.
Now look at another area; Bass. That's much more difficult because the room is so important. That doesn't mean a demo is worthless. Trying a certain amp with a certain pair of speakers can, at least, give you some info, but you are still taking a chance without listening to the system in your room.
So, where I'm going with all this is to say that you shouldn't give up on demoing equipment just because you don't have ideal conditions. Pick the areas of sound quality that are most important to you, and focus on those. Sometimes you have to get creative. Sometimes you have to have to take a road trip. That's just the way it goes. I learned from some very costly experiences, myself. I have no problem at all driving several hundred miles to get to the 1 dealer that will lend me the CD player. And then drive 2 states over because that's where the speakers are. (With the rest of my system in the car, of course). Why? Because its so much easier to spend it, than earn it!
