problem with that paratrooper is that who do you trust as a neutral third-party? i mean i read the reviews that a lot of places make, but that doesnt mean that i would trust them to be 100% accurate though. with most audio, just using the equipment tells you if its good or not, but i cant hear most specs to see if they are a little off or not. i dont care if thx certifies the product or someone else, but theres just not really any other certification.
