Wow, that's a pretty hefty mod!

Could you send the exact part names of the capacitors you use? And please also the capacitors you discard.

It would be very interesting to plug them into my test rig (vector network analyzer) and see if there is a correlation between how they measure and how you say they sound.

Thanks,
BÝrge

Hi , tanks for interest. I have discardet ( snaped ) all the big blue 10nf.
Desolder the 470ohm resistors after DAC chip, snapped of the two 2n2 to ground before RCA. Snaped of the 10nf after C15 ( C26 ). And solder 0.5mm silver cable from first point after DAC to RCA.


So the caps: C21/C31 is Elna Cerafine 470uf 25V.
C15 is Nichicon KZ ( MUSE ) 1000uf 25V.
All the rest of the oem 570uf OS-CONs are changes to Elna Silmic II 470uf 6.3V.

Hi, 4545


Great job, and very fun!! How do you like it?
It maby a rollercoster soundwise, one day no bass, one day to hard in top.
But just wait it will be fine, 100-200 hours before its stabil.
