Except, there seems to be a contingent here who absolutely, positively, believes they make differences ( or sell them themselves, I don;t know) and do their best to convince other who are happy with their systems that they are wrong and their systems stink unless they shell out copious amounts for snake oil. A big disservice to the community in search of better sound. I try to suggest facts. Then one can decide if they want to feel better or not. Not everyone knows how IP works so it is not hard for the fraudsters to take advantage of them. Just wanting it is a perfectly good reason to buy it. Ascribing magic to it is not a reason to install inferiority to some one else.
I have stated MANY times, if it makes you happy, then you are happy. Real or imagined as everything we hear is actually imagined.
