Onkyo SE-90PCI Mod (Finally, It’s Done!)
Just finished my Onkyo SE-90PCI mod yesterday. Haven’t tested it yet, maybe later… Don’t have enough time 
Before the mod:
After the mod:
I used various capacitors in this project:
- BlackGate F Series in main supply.
- Rubycon ZL in DAC supply (upgraded from 330uF to 470uF)
- Elna RBP2 in op-amp supply
- BlackGate NX Hi-Q in DAC->op-amp coupling
- SideRealKap in op-amp->output coupling
- Some Rubycon ZA and Elna Cerafine (non-polar) in other sections
I decided not to change the op-amps (yet). Would try it and made sure I didn’t make any mistake 
My target was to use AD825 with SMD->DIP back-to-back adapter. Would see how did this “monster” perform before I decided to upgrade the op-amp.

Why didnt you seperated the two big yellow non polar capacitor? (like howthe orignal with the copper plate) BTW, You should also do EMF/EMI radiation shielding back/front of the card. anyways, awesome blog you have. i just bookmarked =)

Sudah ditest apa belum bang? Gimana hasilnya?

I still waiting for the result and the opamp mod result.
The downside from this mod is this card will take 2 slots of your PCI space.

Can you teach me how to mod SE-900 onkyo sound card. I’m also, using ESI Juli@. Both of them are very high quality sound card. Will you agree?
Where can I buy those High quality CAP
Thx for your professional advise.

You can buy those components (most) at your local audio shop. You can search online also.
Thank you.

Can you explain every parts that you’ve changed.. why did you chage it and why did you choose those parts as a subtitude, is there any reason?
Thanks

Here is a little snippet:
- Black Gate is a must for PSU Filter if you can afford it (I used the “cheap” F Series)
- Elna BP is good for opamp PSU
- BG NX Hi-Q is for first stage coupling
- SideRealCap is for second stage coupling
- Others are “standard” Rubycon ZL and ZA
Reason? Simply just follow your intuition and from your own previous experience in those caps.

Dear friend,
Can you let us know what is the outcome after the SE90 PCI MOD ?
Thanks.
