I have made the move and there really is no comparison: the PSA PWD MkII, once burned in, is audibly superior in every respect. That said, I enjoyed and respect the W4S DAC2 and could have happily continued to live with it. While it does not have the inner detail, crisp highs, or thunderous bass or soundstaging of the PWD MkII, it had an ineffable organic quality to it that was very pleasing and liveable.
So if you have the coin, the change would be very rewarding; if not, I would not in any way feel audibly deprived.
