Hi ADA,
Have you remove the C261 and C260?

原本唔想太早出報告, 但實在太實在了.
測試方法: 未換TCXO前先聽幾拾次隻歌, 跟住全速改機, 改完機即刻試聲, 跟住run-in幾日後再作比較.
測試CD : Alan Tam cheap版 浪漫經典第二輯, 只需68蚊(其實我最鍾意用cheap版試聲, 因為比較容易試出分別)

TXCO : 連PCB所有費用 $150

報告:
人聲好出...呢點好明顯, 好容易聽出分別 , 高音令左, 清左, 低音快而準.
今晚試大型古典音樂.
小小總結: 150蚊升級真係超晒值, 完全唔同晒, 可以話脫胎換骨.
根據網上文章, 這東西萬試萬靈, 有電子功架的師兄真係要試. 幾乎所有CDP都合用.

Should be have a lot of fun!
因為星期五放工唔記得帶粒TCXO返屋企, 所以無開工, 卒之琴日有時間即刻做PCB...銲零件...搞到好夜...
所以 ...
