Can you describe the difference AKD32S and AKD32P for sound quality?

Why should we buy new DAC?

The lead time is because only engineering samples of the chips are available now. These may have issues so best to wait until production samples are ready.
Also, promotional price for limited time and may change later.

Hi Acko would you (or did you) consider using the ES9311 Low-Noise, Low Dropout Regulator for the ES9038PRO chip in any future design?

This is being evaluated but initial tests indicate not much difference compared with the AKR75s using the ADM7150s

... but the 9038PRO did take things to greater heights in my system 🙂

Good! I will buy AKD32S and AKR47 to compare with Northstar excelsio (ESS9018)

For regulators the AKR75s are better than AKR47

3.3V x5
1.2V x3

If you get the entire set I will throw in the base board to mount these for free

Your mean is that AKR75s are better than ES9311?

No difference on my setup.

Will you provide the guide for upgrading the board?

Board is already optimized so there is nothing much to upgrade. Also, some tweaks will be done prior to match if you get the AKR75s. You should really be focussing on the IV stage to bring out the best.

LL7902 is good for IV stage?

How have you set the programmable THD compensation?

How have you set the programmable THD compensation?

via an external i2c controller if you know how to set the registers of the 9038PRO

There are many out there, I will have to check further... recommendations will be in the users manual.

I haven't compared this myself but I have reports from users that the AKR75s also outperforms some of the popular shunt regs out there!
