I just gotta comment about subliminal messages in this post. Lets think about what is being done by some salesman/vendor who 'suggests' but not directly, any number of things that we might doubt about something that we don't fully understand. Just to make sure that everything is going to work swimmingly, here comes a little gadget that fixes a problem not thought of before. It can be true or not, that is not so important as making your audiophile assured that a ghostly little demon has been put back in the box.
On another subliminal note, I recently purchased a 'sleep machine'. It makes soothing noise that may help you clear your mind and go to sleep. HA! not me, I ANALIZE the sound (subliminally of course), and start to hear what sounds like voices just below the noise. Worse yet, with a little imagination, I hear "guilty, guilty" just under the noise. "Hello, is Dr. Mindblone there please? Yes, I need an emergency appointment." Baby steps, baby steps.
