摘录一段给楼主看看The ALC885 used to be the high-end codec, and is still used by DFI for their mainstream, (with the ALC889 creeping in at the top end). It is fairly competent and is good enough for most uses with its >100dB SNR. The ALC882 is similar. The ALC888 (in many variants like ALC888S and so on) is the most common codec seen today. It's predecessor was the similar but slightly lower performance ALC883. It is OK, but falls short of the desired 100dB ADC/DAC SNR performance that enthusiastic samplers or music lovers want. MSI seem to have the ALC888 implimentation at its best, although that is the best of a mediocre job. The ALC889/889A is an upmarket ALC888 and easily meets the 100dB SNR. I suspect it is an upgraded/graded ALC888. The ALC889A is a Gigabyte designation. The ALC890 is another improved ALC888, but only used by Asrock and probably a rebadged ALC889. ASUS have a non-standard codec, the ALC1200. This is believed to be an ALC888S or T in drag. Since Gigabyte have their own "type", Asus had to have one too. : c) |5 P6 H% [# i7 z* B: b# V/ W5 S3 {, _( b b. c0 L" k: n; k0 P. x6 }
