sound distorted from Jolida JD100H

[maya1]

Hi everybody
I have a problem with my Jolida JD100H.
I'have changed the 13 diodes on PS board and the 4 caps 3.3 mF 250V at the end of the signal.
I have placed:
-no.4 of International rectifier 8A 600V HEXFRED ;DIODES 53562
-no.9 IXYS 12A 1200V uLTRAFAST(FRED) ;DIODES 64784
-no.4 Capacitors Auricap 3.3 mf 200V ;AURICAP 66001


Now,I listen the sound very distorted,dirty from some original CD(i.e.:The last of Avril Lavigne).
This didn't happen before these upgrading.
I have tried to listen the same CD in an other player and I have listen it correctly without distorsion.

What can be the cause of this failure?Diodes,caps,laser setting,or......?

Thank you for your help.
