Basically, I just got my first decent set of speaker about 1 week ago, the HSU HB-1, and was blown away by what a decent speaker is supposed to sound like. And then I said to myself, what if I actually drop more coin and get a better set? So now I am wondering whether I would notice the difference between the HSUs and the Ascend CTM-340 or the Sierra-1s. Any thoughts? Is it worth returning the HSUs and buying either the 340s or the Sierra-1s? Would a neophyte ear notice the difference enough to justify the price?
