Is this some kind of trolling? Please record the output of the same signal at unity gain under Linux and Windows, preferrably via a digital connection, align the streams and check for any differences, especially in the resulting spectra.
It might be possible there's some poor resampling or erroneous datatype conversion in your signal chain, probably in userspace. This would explain why it occurs on all your cards.
What you can try: playback of a lossless (read: wav, flac) file directly to ALSA without dmix, pulseaudio, phonon or whatever. This is your baseline for comparison. If this "really sounds worse than Windows" (I could hardly type this undifferentiated phrase), then it's some DSP code on the Windows side.
