At least you admit that you "don't know". That's a good place to start, rather than to think that if it's cheaper, it must be as good or better. as some do. There's a great line from the movie "A Thousand Clowns", which came out in the early 60s and is one of my favorites. Martin Balsam plays financially successful older brother to Jason Robards who plays a sort of devil-may-care beatnik type who is financially careless at best. (There were Beatniks in the 50s and early 60s.) The two brothers are having an argument about life philosophies, and Martin Balsam says to Jason Robards, with irony, "I get it. If I'm so smart, why aren't I poor?" The take home lesson for audiophiles being sometimes there is a correlation between cost and quality, but not all the time.
