Realtek 889a vs VIA VT1828s vs Realtek 888

Hello,

Before reading a P55 mobos review at the TechReport I though that Realtek 889a and VIA VT1828s should perform the same but it looks like 889a scores a point better in almost all of the RightMark Audio Analyzer benchmark. I am not familiar with RightMark and don't know if the scores have any relevance to normal use. Do you know if the difference between two chips can be audible in every day use?

Also, how does VT1828s compare to the older Realtek 888 and is that true that I should avoid VIA codecs?

Thanks a lot in advance for your answers and suggestions.
