Hi,
As a NOS dac lover, because of its respect to secure sample timing, i wonder if this new ESS Dac comes closer to the natural tonality known by, for example, TDA1543/1541?

I don't have much experience with such "classic" NOS DACs, but what I can tell you is that the 9028 does a better job at pretty much every aspect of the presentation compared to the 9018. This includes soundstage and detail resolution.

Hi Dimdim looking for some help please.
I am just in the process of making up link cable.
Should I use
pin 1 of shield to 3.3v Vcc of my dac pcb
pin 2 of shield to SDA of my dac pcb
pin 3 ?
pin 4 ?
pin 5 of shield to SCL of dacpcb
pin 6 to GRD of dac pcb.

Do I need to connect any other wires from shield to dac pcb or modify program because you mentioned the GP104 line on buffalos and side car control pin 3 ?.
Thank you for fast postage of shield pcbs and your help Dave.

Hi there Dave,

To connect to the DAC you use header I2C_ISOL1.

Your pinout is right, you just need to connect the GPIO4 pin (pin 26) of the 9028/38 to Pin 4 of the I2C_ISOL1 header.

I don't remember you mentioning whether you have access to GPIO4 (pin 26) or not. If you don't, you could use either one of pins 27, 28 or 40 (with some very minor changes to the code). If you have no access to any of those pins, I'll have to do some changes to the code to get it to work. But it is best / way more "elegant" if you use one of these pins.

In your case (DIYINHK ES9038Pro DAC) you don't need to connect pin 3 to anything.
