Don't forget that all sound production has become more and more compressed and 'tweeked' for the digital(Mp3) format now, and that it's all lost it's original depth and wetness to the sound produced by analog(magnetic tape). Due to the over engineering and sound transfer through all the electronic equipment it actually sounds worse because there's too much going on in the transfer that it becomes more difficult to sound correct, kinda like when a guitar player has a good amp and used to plug right into the head, but now, he plug's into a processor/pedal, etc and then there's so many option's that he end's up loosing the 'beef' tone, mids, and gain(volume), just to make it 'sound' better. That's also like when you take a 69' RR and see the simplicity in it and then try to understand the computers and etc in our cars, it becomes much more of a hassle, in hopes off the same result. (Is it better?) Ya, at XM and Sirius it sounds proper, in the room they're broadcasting from, but by the time it gets to our ears it's been diminished to the 'best' quality available. That's why your cd's/direct sources all sound better than sat radio. Unless someone's of a younger generation and never heard any songs on vinyl before, then you wouldn't know what music is supposed to sound like properly(through speakers), with all the mids and acoustic balance. Nowadays the treble is mixed and turned up so loud to make it sound 'clearer', it end's up taking away from the overall sound mix. Anyways, I don't think there's a win here. Just assume the speakers aren't blown unless they really sound worse than they do now possibly one day lol.
