I was referred by a customer to this website! Happy and surprised to see my DAC is being discussed here!
The long waited DAC has arrived! Some of the bros around the world (S'pore, USA, Japan, Ukraine etc) had collected the DAC from me. Allow me to start this thread to share some info of the play-ability of the Soekris R2R DAC.
The Soekris R2R board has a built-in uManager, whereby user may program / parameterize the DAC setting (particularly the Filters) to obtain the desire sound by changing the filters selection. The RS-232 serial port is available at the rear panel, you'll need the following to get into the uManager:
1. Computer (Windows based preferred)
2. USB to RS-232 Converter (most computer nowadays doesn't come with this port, you will need a converter)
3. ExtraPutty Software: Link here (http://www.extraputty.com/)
4. Filters file compiled by others (or you may compile your own if you know some software skill!)
There are details guide all over the internet to guide you how to connect the computer to the Soekris DAC. I'll just point out a few key steps:
1. Connect USB to RS-232 Converter to the computer
2. In Device Manager, configure the RS-232 port baud rate etc to (115200, 8, n, 1), take note of the COM port #
3. Connect the RS-232 to the RS-232 port at the rear panel of the DAC
4. Power On the DAC
5. Launch ExtraPutty, select Serial connection, the COM port and key in the baud rate, then click Open
6. The following screen will be shown:
7. Type "+++" (the command to call out the uManager), the command line manual will be shown:
8. Now, you'll see the firmware of the Soekris DAC. All DAC is shipped with latest firmware v1.06
9. Have your desire firmware/filter files ready, key in "download" on the cmd line screen
10. While the download is waiting for a file to be transfered, in ExtraPutty windows, select File Transfer -> Xmodem 1K -> Send. Browse to the firmware/filter file, and you're ready to transfer!
11. When the transfer is completed, you'll see the following display:
12. Type "Set Filter" to change the type of filters. In general, you can choose the following. It depends very much on the type of filter file you loaded to the Soekris DAC. T
set filters = Linear
set filters = Mixed
set filters = Minimum
set filters = Soft
These are some of the useful link online you may like to refer to:
1. Access uManager (http://www.dimdim.gr/2015/02/soekris-r-2r-firmware-upgrade/)
2. Soekris Official Site for Firmware Updates (http://soekris.dk/download.html)
3. Filters discussion thread @ diyaudio (http://www.diyaudio.com/forums/digital-line-level/269776-filter-brewing-soekris-r2r-133.html#post4729771)
That's about it. Have fun & enjoy the music!

Operation of the DAC is pretty straight forward. There are three digital input namely USB/AES EBU/COAX. Plug in your digital input to these connection and you're ready to go.
The Amanero USB required a driver for Windows, it can be downloaded here: Download (http://amanero.com/drivers.htm)
Depending on your downstream equipment, you may choose to connect either RCA/XLR output.
There are two different output mode, FIXED or VAR.
In FIXED mode (toggle switch @ up position), the analog output RCA & XLR is maximum @ 2Vrms & 4Vrms respectively. Also, in FIXED mode the headphone outputs are disabled (no one would like to blast the headphone at max volume i guess? ;D)
In VAR mode (toggle switch @ downward position), the analog output RCA & XLR can be controlled by the volume knob. Also the headphone outputs are enabled.
Very important, in FIXED mode, the volume is at max. If your downstream equipment is a power amp, the power amp will be at max volume, your speakers probably cannot take that kind of power. If you like to use the DAC as a preamp for a permanent setup, I'd recommend to block the toggle switch with a pc of small plastic block inserted to the hole of the toggle switch. I did it this way so that my daughter itchy hand cannot toggle the switch to give me a heart attack! ;D
Also, I'd recommend to power off the unit should you like to change the mode. There is a known feature in Soekris firmware whereby switching to VAR mode, the analog output will be able to adjust to +10dB (> 2Vrms & 4Vrms respectively). When switching back to FIXED mode, the analog output stayed at the +10dB, for some digital input with high signal level, this +10db will result in saturated peak value in some case (layman call it distortion). To mitigate this, always remember to change the mode only when the unit is powered off.

Czy on nie pomylił forów? U nas chyba nikt o tym dacku nie dyskutował?

Spamuje,na AS też powiesił.
Ops, my mistake? I've seen VINSHINE AUDIO being discussed here.
My apologies :-[
Jesteśmy otwartym forum hmmmmm i osoba z zagranicy też może nas czytać . Kurde sam nie wiem co o tym mysleć?
Potraktujmy ten wątek jako platformę do podyskutowania o przyjętych rozwiązaniach. Jeśli będzie zaś zmierzał w kierunku sprzedażowym- przeniesiemy do działu sprzedażowego. I tyle. Osobiście cieszę się, że czytają nas w Singapurze :)
Nawet jeśli przez pomyłkę ;D
A jednak było w tym wątku
Stąd ten wpis od Alvin1118.
:o :o :oDziki też człowiek ;D
the power of google brought me here in this forum ! 8)
Collected mine on Tuesday night and only have chance to play few random tracks (redbook and hires jazz, classical and new age) late last night.
The DAC is automatically recognised by the Auralic Aries mini, when the blue lights stop blinking, that's when the magic or music start to flow. And the amp finally can flex it's muscle with the fully balanced output feeding by the DAC to preamp and power amp upon its arrival.
In such short time before the DAC has fully settled into the man cave, I am still getting used to the sound. But for sure it has very good clarity, separation even brand new out of the box and at low volume.
Hope to hear more when it's warmed up to the new home. Thanks Alvin for the MO.
Got mine yesterday. The build quality is top notch and chassis is very solid.
As for the sound, it's pretty much in line with the general opinion. It's a little warm sounding but highly resolving. It's definitely worth a try.
Have been listening hours after hours, I thought my Yulong Sabre DA8 has given my the pleasure of enjoying music, this new Dac is even better, both USB and coaxial are simply magical.
I got my unit last week but did not have the opportunity for a serious listen til much later...I did hook it up for a quick listen earlier on but felt it would be a mistake to form any opinion on it til it has been given a chance to settle in. A repeated playback of a burn in track helped.
To cut the story short, the build of the unit feels solid with a heft that inspires confidence. It looks and feel very well put together.
The SQ after the brief burn in period sounded substantially better than my initial impression. The sound is tonally balance in a way I like. No harshness yet the details are there. It has an organic feel to it with the images kind of having a 3D feel to them. I really like the sound I am gettng.
Thanks Alvin for getting this project done. It was a longer wait than expected but great end result.
(The DAC) Already it beat my red wine audio isabellina with full options with premium tubes..
It is honest, you will not believe the amount of headphone amps I have.....Heh heh... the a/b (test) is not from memory. ....that is why I don't sell my used amps...Also wanted to be sure the sq are different in a way not from 'maybe' or memory but actual same source, same headphones.
I too, will buy another set if I have extra cash....it is that good, I have lots of tube amps, lazy to unplug and plug the cables, there is something about the r2r dac.....I am not good with words but the ears cannot lie, it is just very additive. I have about 20 headphones from cheap to hd800, t1, ps1000, low impedance to high impedance, it just drive them well to their potential. Except that the high impedance ones, the volume is at 12 o'clock onwards and I feel good that I am able to turn to 12 o'clock as even with amps designed for high impedance, I am not able to turn above 10 o'clock before hurting the ears.
After >48 hours of running in. Had a longer listen to this DAC.
My setup is melco N1A--> wireworld platinum starlight usb--> vishine DAC
Usual setup is melco--> stock melco ethernet cable--> lumin A1
Compared to newly opened unit, the stage does open up. The signature would be warm as compared to lumin in my opinion.
Again, the presentation is punchy and plenty of bites. Good for pop, rap, R&B songs in my opinion. Good attack and I enjoy when I listen to these genre of songs.
If you are using usb interface, I would recommend to invest on quality audiophile usb cable. I get more transparent, lower noise level, better bass extension with wireworld usb cable as compared to the stock usb cable.
Sound stage opens up after running in, with improvement of depth. Lumin A1 streamer + DAC does have wider stage , more layering and holographic sounding.
Considering the price difference (lumin A1 almost 4 times more expensive), one should expect better performance by lumin.
This DAC performs well above its price. I have heard worse performance in similar priced DAC, and even some more expensive DAC.
Overall it exceeds my expectation and this is a good buy for those looking for value for money DAC. Especially now having promotion for the loan program.
Going to pass to the next person, let's see what other bros think about this DAC.
Firstly, my sincere thanks to Alvin for organizing this tour and Stanley for the hassle free delivery. The unit has just been passed to Ricky this evening.
The 3 days spent with the Vinshine DAC has been pretty positive, as this is my first real experience with a R2R DAC. My current setup is the Lumin D1, Amtrans APCG-01S (very generously on loan from a bro), Bel Canto REF500S and KEF LS50. With the Vinshine DAC, listening was done via USB from my laptop with the JRiver software.
I first spent some time on the headphone out to get a feel of the unit. It had a slightly warm and dark signature with a meaty tonality. With my Fitear TG334 on a Toxic Hydra silver litz cable, it delivered a very good performance with pinpoint imaging and quite good separation and details. Soundstage depth was very good with believable width. This was a particularly pleasant surprise, as the headphone out on most DACs usually only deliver decent and unspectacular performances.
With much anticipation, I hooked up the unit to the preamp and powered it. Initial impression was not positive; it sounded hazy and soft, much like the rays from the sun trying hard to shine through dark clouds. I figured that it was just a 5 day old unit and left it to play overnight on soft volume. After a night of playing, as expected, the sound quality improved significantly.
As a dedicated DAC, the signature of the unit very much mirrored the headphone out; slightly warm and dark sounding, with a meaty tonality. It also had a organic and slightly holographic presentation, delivering a smooth and non fatigue listening experience. Despite the meaty tonality, it was not slow sounding, and Rock music sounded right. Resolution is pretty good and details were presented naturally and never in my face or forward. Bass was punchy but could be tighter. Vocals was organic, natural sounding with finesse. Treble was extended and smooth.
In conclusion, there is much to like about the Vinshine DAC. It is slightly warm, organic and smooth while retaining good resolution. The above average headphone amp on board and the ability to be used as a preamp adds much value to the DAC as well.
