Not sure this is necessarily the forum for this, but it probably has more to do with motherboard signal trace layout than the codec, though I have certainly heard good things about SoundMAX codecs before. ADI makes products designed to go into hifi equipment, so has the engineering knowledge to get things right. Realtek makes audio chips just so they can have more chips on the board, if it already has rtl Ethernet and/or Wifi.

I upgraded my system from a Asus M2N-E (Soundmax AD1988 codec) motherboard to MSI X58 Pro-E (Realtek ALC889 codec).

The problem is that I feel the sound worst than before. I feel lack of bass and treble. With AD1988 the sound was more "vivid", there was more bass and treble. With ALC889 it is "flat".

The only advantage I noticed on ALC889 is the possibility of mixing multiple sounds at hardware level, what was impossible on AD1988.

So, what are your opinion?

Ps: I used on both the analog output with a Edifier E3100 2.1 speaker system.

Ps2: could be a problem with a bad quality DAC of the Realtek ALC889?
