Good question. Since you asked I started to think about it and come to the realization that I haven't really liked any stock systems. With that said, I haven't really touched my car stereos. I am a bit of a home stereo audiophile. I'm not a big fan of Blose in general. Their home stuff IMO is better, but I wouldn't buy it because it is way overpriced and you can get better stuff cheaper. The Blose in the Z32 was HORRIBLE. The head units would fail quite often and have to be replaced. Then they used inline amplifiers with the speakers so it made it a (minor) pain to change out the head unit and keep the speakers. The speakers weren't great either so those were often replaced. The one in the G was OK and sort of similar to the GT-R. The system doesn't have the range I'm expecting. Then the sound quality between the different inputs also drives me up the wall. Actually, I think the radio in the G sounded better than the GT-R. I've considered putting in a different system, but I rather spend the money on modifying the car and listen to the engine and turbos instead
