Hi Guys,

I'm always up for a great project. I'm in for a SE Dac + PSU, updated the sheet.

Thanks,

PJN

Hi all

The GB is going on the right way, but we perform do better.
Glad to see that Jean-Paul has posted some good informations
My V2.6 ES9023 is now improved with 2 BlackGates in C10b & C32 positions.
Result : deeper bass (yes it's possible) and more global definition in the soundstage !!!
The output level gave a strong & clear signal, my pre is now on -30dB.
This board is a real bargain, can't wait to build a BAL version using V3 PCB.

Phil

For optical can I use the TOSLink module from twisted pair audio? Is any kind of input-output "matching" that will need to be done or just connecting the output leads to some place on the PCB? Any other TOSLink options?

Hi Ryssen and All

Ryssen
Glad to see you've finally been delivered
Enjoy your built, take your time, read the Build Guide too.
BTW read the EU Parts GB there are some hints about parts.
BG went from a friend old stock, he picked up two units for me.

grufti
BlackGates : NX HiQ 47uF/6.3v at C10b + 0.47uF/50v at C32
They seems to be available here : http://www.partsconnexion.com/capaci...e_blkgate.html

atharva
TP TOSLink module needs to be fed by SPDIF Data stream & requires min 5v external PSU as it has a 3.3v onboard reg. It's just a media converter Cu to Optical Fiber.
No input-output "matching" needed, just connect SPDIF from ES9023 to TOSLink.

I asked them and they are out of stock,
They recomend the ELNA Slimic or serafine as an alternative.

Can't understand, they are online, seem to be available and finally not

Take time to taste your actual caps before modding
