I am not sure it was just me or:
I did some test and feel the songbird in OSX sound worse than foobar+ASIO in Windows xp. It just give me the feeling like foobar's sound is way more clear, clean. Even my girl friend can feel the difference.
My test setup is:
Songbird:
macbook pro + Creative USB sound card(cheap one,I do not have DAC yet)+DV 332+HD650
and
Foobar+ASIO(did the setting as
ASIO4All Explanation)
T61(windows xp sp3) + Creative USB sound card(cheap one,I do not have DAC yet)+DV 332+HD650.
