How would you modify Sony DVP NS900

I have two outputs in the player and I will put AD8065 to one and OPA627 to the other and plug them both to my preamp. It is easy compare them by simply turning a knob. Eventually I can make the decixcion which one is the best. It is possible that there is no order of superiority and I keep on listening with them both 😀

Are both outputs coming from the same place? I havent got the service manual for this one, but on dvd-ns905, the front out comes from a different dac. Btw, have you measured dc offset before the output capacitors ? If you dont have any dc offset, maybe it´s worth a try to play without capacitors. On my dvd-963sa, this made a big difference (although I got som dc offset )

Yes they do have separate and different DAC chips but the sound is very similar in my player.

I've measured DV offset (3.8 mV if I remember correctly). I use a passive preamp and a power amp which doesn't have DC blocking >> I cannot remoce the caps.

Hello, Diar!
You upgraded pulse power supply capacitor (400V) with Blackgate? This is a good tweak.
