Thanks.
No, I have lots and lots of different hardware. Windows 7 sound is the worst, sandy, Win 8 is soooo soft, like Sony HiFi audio (if you remember the late 70s-80s, of course, you'll understand). XP isn't far away from 7, a bit punchier, but also over-bassy and flat (poor surround), like they smash you straight in the face. But if you listen to CDs with their 16bit primitivism and over-loaded, highly compressed to the "brick wall" audio, which totally suck in the first place, probably you won't notice.
Edit:
Read about loudness wars, and even if a CD is properly mastered, 16bit is still not enough. It's 60s tech.
