To the OP, Here is an Anandtech review of 4 boards including ud3h and Extreme4
, might help you decide.
Another thing I like about Extreme 4, you get a total of 6 fan headers, 3 of them on top above and to the right of the VRM, really help you when you have top/rear fans to plug in.
Better VRM, less ripple, higher frequency with less voltage as a rule.
Can't give you a source for audio, but using common sense and known examples we have:
An audio codec can be shielded to reduce noise, and not. Obviously you will have worse quality when it is not shielded (note I am not saying to what extent).
If we also take let's say Galaxy S 2 and Galaxy Note, they both use the same Yamaha DAC, but Note has better sound quality due to better implementation.
I didn't say in anyway that Extreme4 has actually worse or better sound, but potentially not all ALC898 sound the same.
Also they are many other factors. After digital signal (a typical mp3 file) is converted to analog everything plays a role. Gold platted plugs, good cables, traces on the motherboard itself, and etc.Edited by DeXel - 9/17/12 at 6:17pm
