Great board to make killer dac with freedom to provide dedicated best of the best PSUs of own choice. Do not understand why all 12 pcs not back ordered yet, at this discounted price ))

 

[acko]

Board design still in progress ~70% …

What are current rates for 3.3 and 1.2 supplies required? If go with dedicated PSUs.

Pls Check data sheet for some details. More information when tested later… 1.2V type (DVDD) may need some peak handling capacity ~1/2A+

Indeed. Perhaps because the biggest promotor of this DAC chip was banned on Diyaudio...? 😉

Take the leap guys...

Actually, need to test some of the claims. The ones that I could remember:

1. Async mode with just a single clock is good enough. No need for all the complexities of Sync clocking, dedicated clock boards, etc

2. Forget DSD, especially those upsampled pcm->DSD. The HyperstreamIV modulators are game changers. So, no need for the likes of HQPlayer churning out on gas guzzling PCs or those pcm-dsd FPGA hardware.

3. Also, no need for all these FIFO reclockers or pre-processing

Absolutely simplified and yet better than anything else 😁

 

[fedde]

Yes, and that cheap ChiFi 9039 DACs would quickly flood the market..

That would simplify things, but claims are hard to believe ..

 

[acko]

I am keeping an open mind as we progress …

FYI, the banned member hasn’t reincarnated onto myself or pulling strings so even if I sound similar just purely coincidental 😉

 

[Charcoal]

I think reincarnation supposed to be assigned to me . Don't know the story of this legendary person though ))

 

[fedde]

All traces were carefully removed by the mods... 😉

I still hope for this small miracle though. Let's try it out...

If you are referring to member Endo2112 and the thread "The new ESS ES9039Q2M" he promoted ES9039Q2M and especially the evaluation board. So different DAC chip and not the best implementation.

 

[Sabrosa]

It's a shame that thread was fully deleted instead of just locked. There was some good information shared in the early posts before it went off the rails.

Yes, Endo. Different chip, but very similar tech. Same modulator and probably also same jitter suppression method.

HQPlayer developer, on another forum: " What I measured recently for example on ES9039Q2M based DAC, it performs the best at DSD256 from purely technical point of view. Similar to earlier with ES9038Q2M. So there is still some benefits of shorter path through. With PRO models it also largely depends on the chip configuration and how the analog stages are implemented, with Q2M it is more straightforward"

Of course he could be biased, as HQP is ultimate online upsampler/converter))

 

[fedde]

He only talks about measuring, not listening...
