今日*的*起個心開工, 攪好開聲, 我就唔覺 LKS 飛咗上天, 要量化我會話約 5%, 每樣都各就各位, 各施其職{:1_ ...

orrayyau hing,  

Please resolder the wire when you have time:
-disconnect the GROUND wire in the source side near the PSU IC.
-connect the Blue wire directly to the centre pin of the jumper,  disable the jumper,  the jumper will create additional phase noise.  

you will have ONLY 3 wires,  5V input on the left,  Blue wire OCC Silver to the centre pin of the jumper,  and red GROUND wire on the right.  

it is the best way for soldering.  Single GROUND point always the best.  You will hear the difference when you solder the Blue to the centre pin and bypass the jumper.  If you do not need to do A-B Test anymore,  solder the blue to the centre.

Best,
Blau

其實我覺得未換 clock 前同部 oppo95 分別不大，最多只有5% difference，但加左clock 似係唔同層次既野， ...

師兄 sorry, 可能我評分較孤寒，因為啲朋友成日講，呢様好 2-30%，果様又幾多%，換咗咁多野又唔見啲聲好一倍？先好果小小……

其實加咗之後係聽得到嘅改善，所以我話一定要加，並唔係果啲：    唔，好似高音鬆啲，响低音好似快啲緊啲 ——呢啲類似似有似冇嘅感覺。我係用 The Well 笫七首去比较。

Single grounding 比我想像中影響大，雖然昨晚只係剪了左邊的 Ground，但原來之前有的毛燥減少了，更加靜，人聲更甜滑，音樂再多了點細節，bass 也多了彈性，之前的 bass 是散了點，連老細都覺多了立體感，真係有 d 意外…

果然, 用 QA660 不停咁煲咗佢幾日, 佢有 10% 改進。

睇小平兄咁寫, 有啲等唔切

ozrayyau hing,

Just cut the GROUND on the LM1086 side,  it is easiest . Not diffcult to implement at all.  The reason for cut the left hand side rather than the other side is , the right hand side got a cleaner ground and wihtout components nearby

You can compare two ground point and hear the different.  

actually  ,  if we do not need to do A-B test,  solder to the jumper pin directly  got the best performance,  the Jumper itself create additional jitter.   

For soldering to the EXTNERAL CLOCK pad is for AB test,  if you hear the improvement  by implementign the clock ,  do the ultimate way and disconnect the jumper.  

You hear 10% improvement from Sunday's performance is NOT because the clock is more accurate,  it is just because the Discrete linear PSU need burn in for its components.  

CHEERS!

Thx ching. 今期除左換牛外，Ben sir 的 discrete 穩壓 for 9018 係另一驚喜之作
