I know you said you went back to get everything re-tuned, but I'm in agreement with all those saying there's a tuning issue here. Regardless of whether or not it's a stock head unit, with that processor and amp driving those speakers, you should still be getting pretty nice sound from that gear.
That being said, like you mentioned, when you're dealing with high end equipment, unless you're listening to non-copied CD's or 192+ bit rate digital audio, great speakers are only going to make the imperfections in your music that much more obvious. Crap recordings are crap recordings no matter what equipment they're going through, but good equipment is just going to make it sound that much worse.
