Eric, that's why I use dealers and purchase from them. They are the ones who do the work as they carry what will work together best and what will be reliable (they can't make money when things break down).
Too often folks just buy 'top rated' this or that or component of the month. I found a speaker I love and then I listen to the dealers as well as what the manufacturer uses and it's a start.
When reading posts online, you see where spec defy reality. There are just too many factors like room size, ones own hearing, what's in the room (room sound) etc... Yes, trial and error is a huge part of this hobby isn't it? I may read threads and mags, but my ears are always the final factor. Just because a high efficiency speaker seems easy to drive, that doesn't mean it the electronics will sound good with them, just that they can 'drive' them. I'm not an engineer, nor do I need to be to know what sounds good.
I don't have the money for trail and error purchasing and selling like so many seem to have (or they do it and keep loosing money on the treadmill) so I audition before purchasing. It's very rare that I don't and that includes my high priced cables and cords. That's just me. We all have our own way to purchase and I'm not dissing anyone else's way. It's all good and it's still all about the music for me.
