Loan money is nearly depleted now after checking the balance. Reading glasses ????????? i have contacts, and what is a mavis beacon? lol im confused now.

Anyhow, my clock, psu, and op-amps are back in the new player, along with HDAM bypass and headphone circuit removal. Boy does this player sound sweet. I haven't had a proper listen as most people were in bed by the time i finished, but a bit of 'we are scientists' sounds gorgeous through my grados right this moment

Is it a good idea to replace all the output filter cap's by silver mica types?

I found it helped bringing out the small details in the music and a little better channel seperation but I changed these at the same time as fitting 0.1% tol resistors.

I found changing silver mica caps all over helped alot especially with delicate treble.

I have fitted my upgraded reg pcb for Servo , RF and HF.

Its now running and im listening to Diana Krall the girl in the other room cd.

Already the treble is tighter and more revealing with more 'air' to her vocals. Also the symbols are even more apparent than before.

It has a more 'Live' sound to the sound.

I'll post pics after lunch

I agree, changing the filter components to better parts with tighter tolerance is a good thing, especially around the first opamp after the DAC. It increases the symmetry of the filter and the cancellation of HF noise. You can also use 1% Polystyrenes (Styroflex) caps. I bought a few more than I needed and matched them as close as I could.
