Dear Viewer,
Yes, I have changed the Zener to 100V one; the one on the PSupply board next to my five BlackGates.
I asked my wife to listen for comparison as well. We concluded the following:
1. Pure Chinese Stuffs --- Beijing 2C51 + BB 2604 ==> Piano in 陳潔麗 really stands out. However, the vocal part is not that 3D ... but still good and clear.
2. Bendix / OPA 627AM changed ==> High Pitch Instruments not that "sharp". Vocals more natural, more details than the Chinese Stuffs.
It is obvious that without touching the Capacitors, the replacement of the OPAM and the TUBES really makes a difference. However, after changing the PS and the Analog part capacitors (and let them run in), the difference is not that significant.
CD33 的分享
發覺在原裝的CD 33上, 換了OPAM 和胆的分別是顯著的. 但當換了電容之後, 這個分別便在收細. 大胆講句, 電容 run in 之後, 可以說是口味之分. 大陸料, 高音樂器似乎較為特出, 但人聱相對比了下去. 用了 Bendix 胆, 人聱較為暖和, 為真.
以上只是小貓心德, 非金科玉律, 請勿見笑. |
