請問SB0460跟SB0550有差在哪裡嗎?
還有只有最高價的版本為SB0550的版子嗎?
謝謝解答啦 ^^

SB0550用了四顆CIRRUS logic的CS4398 DAC ....
跟1212M用的是同一顆.....
OP方面是用一顆NJM2114及三顆NJM2068
1212M用的都是NJM2068而已.....

NJM2114原廠的簡介
NJM2114 is a high performance dual low noise operational
amplifier that could be replaced in application with
NJM5532.Comparing to NJM5532; it has superior
specifications on Slew Rate, Bandwidth and Offset Voltage.
Furthermore lower noise and distortion are achieved, it is
applicable for Hi-Fi audio equipments.

NJM2068原廠的簡介
The NJM2068 is a high performance, low noise dual
operational amplifier. This amplifier features popular pin-out,
superior noise performance, and superior total harmonic
distortion. This amplifier also features guaranteed noise
performance with substantially higher gain-bandwidth product
and slew rate, which far exceeds that of the 4558 type amplifier.
The specially designed low noise input transistors allow the
NJM2068 to be used in very low noise signal processing
applications such as audio preamplifiers and servo error
amplifier.

而SB0460用的DAC是CIRRUS LOGIC的一顆CS4382負責八聲道的解碼
不論是DAC OP 和AD converter 都差上SB0550一截....

用料方面SB0550和1212M是同等級的東西甚至更好....

應該是只有ELITE PRO才用SB0550這張.....

另外根據這篇http://www.hardwarezone.com/article...?cid=30&id=1699
短期內是不會有PCIE的音效卡出現了吧....
