I'm wondering if someone can compare these two. Or if it's already been done, perhaps point me in the right direction, as a search didn't yield anything. I'm currently running the ASIO4All plugin in WinAmp in my CarPC to enable Bit Perfect playback for my Sound Quality system in my car. There is a significant difference in the stage depth and clarity with the ASIO4All plugin enabled. I'm wondering what benefit I would notice by running the KX Driver as the driver for my Audigy ZS 2 PCMCIA sound card (optic out). I currently have bit accurate playback enabled on this card in the preferences. Any insight would be greatly appreciated! Thanks for your time.
