You can check out this site headfishoip: Stereo Headphones, Headphones amp,Amps & DACs, DIY audio kti,Resistorsl,ELNA capacitor,nichicon capacitor Audio Cables & Accessories,cmc,tube you can get some parts here like the WM8741, DIR9001, ELNA silmic II caps, pcm2707, etc.
For the 0.3 ppm crystal you can use the Vanguard ultra precision golden TCXO crystal available on ebay.
Has anyone got a bom I can import directly into Digikey or Mouser?
Oh, just wondering if there are any optional upgradeable parts for this?

Few boards are available for immediate shipping. If anyone interested can pm with paypal id and number of board sets required.
Is there a thread on the construction and general chat on this unit?
I don't want to start asking questions here.

This fully finished DAC of the previous version is not available any longer. It has been sold out.
The larger box under with the big volume knob - what might that one be, any details you want to share?

That's a class d amplifier. My next project is going to be a class d amp and dac integrated together on a single board ES9018+TAS5630. Will post the screen shot ASAP.
Why combine them? IMO it is better if you create the best modular ES9012/18 DAC and a separate class D-amp which we can chose to use or not.

I have already created the TAS5630 amp, its ready. ES9018 DAC, i am creating one right now. For the ES9018 I won't be able to release the circuit diagram because I am kind of restricted, i've signed an NDA 🙂 . It can be easily assembled with the provided board layout for component placement. The reason why i thought of integrating both amp and dac together is you kind of have a nice all-in-one unit in one neat compact housing and cost effective. TAS can be driven differentially, so I thought of taking the balanced output from the ES9018 and drive the TAS differentially. For the volume control and the different settings we can use the open source arduino codes. But yes, still you will be able to switch off the amp unit if you don't want and can use the dac module alone. It is just an idea, I haven't done it yet......Thanks
