AD1862 NOS I2S Boards
I have 9 extra boards that I have from getting my board made. I will sell these for cost plus shipping. $2.00 per board with shipping, somewhere between $5.00 and $10.00.
Boards are 1.6 thickness, 1 oz. copper weight, HASL, 2 layer.
Let me know if you are interested, include your PayPal e-mail address and your shipping address so I can figure shipping; I will send an invoice.
I will send an e-mail for approval of the final amount before sending the invoice.

Nice build!
I have not. No RPi in my house yet
Anyway, @Ripster tried RPi 3B and he claims it works (but his setup can be different from yours, I have a lack of experience with rpi ... try ropieee instead of moode and configure it for the hifiberry dac+ pro as @Ripster said).
Yes sure, Ripster confirmed that he is using Pi3 so then in that case it should be my settings or something else in the setup. Let me try to debug once I get back the dac as it is flying with friends now since more than a week
Ill have another one for my brother, I am sure he will like it
Is anyone aware of a Rochester group buy?
Yes, There are few good manufacturers for R-Core in India,
planning to use R-Core with different taps for Analog section and Digital Section.
Thanks
Well even with ropieee and roon I get the same results. But you have a DAC (hifiberry dac) before the Miro AD1862 DAC. Probably some altering of the signal must be happening there?! The hifiberry hat that i am using as well as the fifopi have no DAC.
Anyway, with roon setup, I can finally do some proper listening and testing of hifiberry vs fifopi and different power supplies. [emoji106]
Well the information about hifiberry i2s header are very poor. So I have no idea what is going on but what I do know is there is no hifiberry driver being loaded since I selected rasberry dac i2s in ropieee... But since you have no dac on digi+ pro I would presume that you need to load hifiberry drivers in ropieee for HAT to work properly...
This morning I put back in the Fifopi, what a difference! Excellent improvement in both tonal and spacial qualities. My idea was to use the hifiberry with the AD1862 and fifopi with Dddac, but this AD1862 dac deserves better!
Currently on the bench again to power clean side of Fifopi with better psu.. Lets see...

I can't ship international at a good price. For that reason, I will only ship within the United states.
The R10 & R11 is output resistor and it theoretically prevents the start of oscillations.
Another function is the prevention of excessive load on the opamp in case there is a short circuit at the output (damaged cable, connector).
Practically it is probably unnecessary and can be as short/jumper ... but the sound will not be harmed with it so you can put the resistor there

yes har297, as Miro is saying : keep it there : 100 to 150 ohms helps more than it arms : 1/4 or 1/8 W is enough, you can try either metal or carbon type to voice little the result : but measure the resistor to try to keep them in 5% precision or less between the two channels (Yageo metal films 1% or 0.1% are good, better than the Dale RN55 and costs less)
