Those purple or pink output polycarbonate caps impart a lot of colouring to the sound.
I don't like the OP42 as IV-converter. Really hate the the temperamental AD811.
CFB opamps sound weird to my ears in the long run but impress on first sight.
YMMV.

Polycarbonate is after PIO one of the best plastic caps. But indeed in my 304 i have MKP motor starter caps, quite good.

What is your suggestion as IV/buffer SeraTico?

I have a simple tube stage in mind, with a switching PS from an old pc or so.

Guido: a friend has an 880 with paper SM. Will copy all. But it is allmost the same around dac as my CD640.

Pro of 880: selected dac, epoxy pcb.

cons of 880: NO pcb gnd shield!!!

I moded once CD880
not much,
NOS mode (override 7220...)
recloced I2S,
discreet IV
that was all
it was really good.
I can imagine with clock generator changed to better one...

But I had some problems about mute at first.
There was clicking between songs.
So I somehow trace the signal (wo manual...)
from some controler chip and it was worked out.

I just changed mine to 220nF PPS, which has made a nice difference, but the most profound change was adding a low-noise reg to the SAA7220 filter.

Hi Lee,

What sort of low noise reg did you add to the SAA7220? Where dd you ground it?

Cheers,

Joe

I keep the 880 dig OS-sed. The 1541 is not the perfect candidate for Non os

In this modded player, the transformer directly sits on top of the digital section, maybe not so good.

I never liked the 880...

[tubee]

Yes i know you did'nt like 880. Maybe the missing gnd screen is a clue?
I dislike the placement of toroid also in that added IV amp.

The 304mk2 is still performing here. No s1, no b digital filter.

Btw do you still have the Sony TA N7B? I try to repair one.
