Hello Myles
Well I don't know about you but I got bit by the bug when I was in my teens. I purchased my first pair of speakers with paper route money back in the early 70's. If I knew then what I know now I might have purchased a different set of speakers but aside from that I purchased what I felt was the best I could afford in my budget at that time.
My point is there are many issues when first entering a hobby and for that matter after 10 years in. Examples being knowledge, listening habits and of course economics that are going to effect your choices. To make a blanket statement that you didn't do your homework is a very narrow view. The speakers I own now could not have been manufactured 40 years ago or 10 years ago for that matter. Technology does change over time and the manufacturing know how to make rolled beryllium foils is a recent break through.
As far as the OP is concerned there is absolutely no useful information on the speaker manufacturers site to determine what you are getting before you purchase the speakers. To me that's red flag to make sure you can return them for a full refund if you are not happy.
The source being the media of choice then yes I agree. I am not saying the the quality of the source components does not matter. Just that there is much less variability with them compared to speakers.
Well in that case maybe we should be more open minded and actually listen to something before we write it off. You don't need a master tape to determine if you have a good speaker or not. It's obvious with well recorded media the average guy can get their hands on.
