「I have tried using OPA111AM and AD8610 as the output opamp after I obtained both :
拿到 OPA111AM及 AD8610這兩款 opamp後﹐立即安裝上 AW-D2作輸出用, 便開始試聲。
OPA111AM : The sound of it is thicker than OPA637, especially the vocals. The vocals becomes more sexy and thick. Bass is a bit deeper than OPA637, but the bass is lose and not tight. So you won’t get a clear bass. The treble extension is not good. Resolution and details is not good either. When I listen to music, a lot of details just disappear. The sound stage is quite flat, not 3D enough.
OPA111AM : 聲音較OPA637厚, 尤其是人聲。聽人聲時覺得歌手的聲線會較磁性一點, 厚一點。低音較OPA637深但比較散, 也較蒙。高音的伸延不太好。細節及清晰度不及OPA637。聽音樂時有很多細節都不翼而飛。層次感也不清晰。音場比較平面, 欠立體感。
AD8610 : The sound is thicker than OPA637. The density of sound is higher. Bass and treble extension is very good. It got a clean, deep and tight bass. The resolution and details is almost as good as OPA637. The dynamic is also very good. Sound stage and imaging come close to OPA637. The AD8610 is a very musical chip, in terms of musical enjoyment, I will rate this chip over OPA637,. It just make you enjoy the music more.
AD8610 : 聲音較OPA637厚及聲音的密度較高。低音及高音的伸延都很好。低音清晰結實及潛得夠深。層次感﹐分晰力及細緻度直迫OPA637。動態也非常好。音場和結像力和OPA637差不多。AD8610 的音樂感很強, 比OPA637好, 音樂會比較生動。所以我比較享受AD8610所發出的聲音。
In conclusion, if you like a more transparent and detailed sound, select OPA637. If you like strong bass, musical and dynamic, AD8610 is better.
總括來說, 如果你喜歡透明度高, 聲音細緻清晰的音樂, 可以選擇OPA637, 如果你要較多低音, 音樂感強和動態較佳的話, 可以試試AD8610。試過幾粒不同的Opamp後發覺Opamp對部DAC有重要的影響, 聲音真的可以相差很遠。」

看了wilmar兄帖子，我也来说一下吧 opa111,2111,都是比较冷门的仪器用精密运放，在量产的hifi设备上几乎没见过。多见于医疗用的b超，CT等设备。 很久前就在台湾网站看到了opa111的介绍评论，然后自己也搞了对试用，只要是摩cd，试过很多运放，包括opa627/637,ad797,op42,s5534等,我得感觉就是opa111属于斯文通透那种类型，相对opa627,它的高频更加细腻通透，但我觉得它去掉或者修饰了极高频，相对就显得宁静，不吵耳。中频就比627有甜味，但不会特别突出。低频就量感偏少，而富有弹性。 我的感觉是听人声，尤其小提琴很好，开很大声听都不会刺耳，我觉得如果用电子管来比较，opa627如果是mullard,那么opa111就是telefunken.. 至于听摇滚，可能真的不合适，因为opa111系列注重的不是低频的量感，它的低频收得比较紧凑，下潜总体没有opa627那么深。 个人意见，仅供参考！
