That seems to make a lot of sense, but also it would require you to have deep knowledge about the stuff you're buying, otherwise you run the risk of getting all the wrong things from all the different places.
That's true, Lohan. Really though, these purchases require a lot of research anyway. I think the extra effort would be well worth it. Whenever I buy a set of something, audio or otherwise, I always find at least one or two things to be subpar and end up purchasing a replacement.
