i think it was a valid question that no one felt like answering, he was attacked, and he got frustrated. the OP didn't instigate any of the bashing that came out of his questions. look above and the forum attacked first.
can a DQXS help his system sound better? sure. will it? depends on the installer. his gear is basic and lacks flexibility. you can't tune a system without the proper tools, i.e. a processor. i guarantee i could take a DQXS and make his system sound better than it does now.
the thing about asking questions is that you don't know the answer, and usually lack enough knowledge to get terminology correct. i don't bash people for asking questions. i help by providing answers. if i can't provide a helpful answer, i don't post. i wish more people behaved the same way.
