Sonny, first of all, congratulations for your great product! I have been trying my DAC on the last few days and I've liked a lot what I have heard! I need to complete some parts on my system to do final tests, which I will report here. I have the discrete shield and the SMPS, plus the pre.
I am choosing a NAA (for convenience alone I don't want to have a PC/laptop connected to the DAC in my living room). I want to have something that I can control form my iphone/ipad and which supports native DSD256 with this DAC. Right now that means no window's based NAA.
Will there be a license for the Thesycon driver in the future? I have no idea how expensive this is for you. This will determine if I consider a Windows option.
On linux, I hear very good comments about the HQ-Player and its option to convert to dsd256 on the fly. How does HQplayer compare to Volumio? My tests now have been playing PCM directly form my laptop.

I was wondering if there's a possibility to use the Pi 2 as NAA since DSD doesn't require much processing when fed from HQ Player to the NAA. It will be already all processed. If there's a Pi 2 image available it would be great. I have a very powerful computer for HQ Player.

I have an i7 for the server, so I could run HQplayer too and convert on the fly. HQplayer seems the best choice, although there were some clicks at song start reported (DSD256 conversion). I need to check the HQPlayer Embedded for de NAA and control apps for iOS (definitely not roon for me ($$)).

Sonnya, when will the RIAA be ready? What design will it be based on? Do you have a price estimate? Will there be a PSU for it?
Have you done any more tests with the DAC, SMPS vs LPS? Still no audible difference for you?

Do - Post 767 has an image for raspberry pi2. (second link)
I have the 6600 non k up and running. I've created a ram disk of 2gb and installed HQplayer on there (not sure it makes a difference...but if you are running 12gb+ memory and not utilising it there is no harm and apparent subjective improvements)
It ramps up to 100% all 4 core utilised at the start and take about 15 seconds to start playing but once music is playing sits around 30% utilisation. I extend the playlist and it works gapless.
My work pc is a fair bit faster, but I would suggest an x99 platform is over the top for this purpose - maybe an i7 6700 would be the perfect fit.
If you don't run a non 2-s filter or push for dsd 256 its instant starts.

Great! I'll have 12 cores to play with so it should be fun! 😀
That AK4490 DAC is just phenomenal!!!!
Do
12 cores won't even notice the load!
Make sure to check Pipeline SDM on Hqplayer or it won't use multiple cores.
Sonny's AK4490 dac is the best thing to come out of diyaudio.com for me since I have been a member.
Note on the Preamp kit:
ribbon cable for the encoder is made wrongly according to the master ribbon cable.
The key tap at the encoder end of the flat cable need to be removed with a knife an the ribbon cable should be rotated 180 degrees
The cable should be mounted as shown on the picture below:

Sonny, is this still something I need to consider when I receive my pre-amp? Or has it been corrected?
I need to save up, to get my hands on the driver as i need to obtain VID and PID from the USB organisation.
I am working on it this week. But i have a couple of layout i have to finish before i start look at the RIAA.

Sonnya, thanks for the reply. I think linux would be a very good solution for the NAA, so IMHO there is probably no "need" for the driver if it is expensive or complicated.
I could be interested in the phono pre, please report on your progress!

Hi, do the DAC need some sort of USB power from the PC or it's completely stand alone??
