The DigiOne comes with two power supplies (wall bricks). You don't NEED to get linear power supplies for it (unless you feel like spending lots of money). So $315 is the full price. I'll only be able to determine what sounds best once I've tried the DigiOne with the R-28. I haven't done so yet.

I do think this is what manufacturer said about their products

The Digione Signature needs 2 PSUs to run.
The player comes with 1 x 5V 3A PSU to feed the dirty side.
We strongly recommend you purchase the battery pack or use a very good power supply for the clean side.

If you want to use the Digione Signature right away, you can purchase an additional 5V PSU from us, but we dont recommend this set up.


Due to my experience the better power supply mean better sound though
Correct me if I wrong on this.
Please kindly tell that which set up and what budget when you compare both of them and which power supply you use also

Will do. I will be using the battery pack for the clean side. The USBridge (which I'll also be testing) doesn't need a separate 'clean' power supply.

From my recent experience with the excellent Ideon 3R Renaissance (http://www.ideonaudio.com/index.php/products/3r-usb-renaissance) my suggestion is to NEVER connect a PC or Mac directly to your dac via USB. Doesn't matter how clean the power, unless you have a high-end dac that cleans and regenerates its own incoming USB signal, just don't do it. With the 3R in the chain, the R-28 sounds like a completely different dac - tight, focused, zero noise floor, no bloom or glare or grain (unless it's in the actual recording). @FredA if you like the sound from your RPi, yo should take the next step and get an Allo DigiOne Signature or USBridge. Both will take your RPi sound quality to the next level. The RPi 3B, good as it is, is not optimised for audio. I have a friend who specialises in the Pi, and he swears by the Allo variations. Still not convinced? Watch this video:

You are probably right. But i have two usb repeaters in the chain, and don’t forget the usbridge is like a pi with a usb repeater. So the difference should not be that big. But that said, i expect allo to release a unit which will incorporate galvanic isolation, which my intona provides. At that point, i will probably switch to the usbridge. In the mean time, i confident i am close to its level of performance with my elaborated setup.

The fact i don’t use ethernet make the usb ports quite silent in my opnion as the pi has the same chip handling both ethernet and usb. This silence has been enhanced by the lps i added last night. This is a critical aspect. In your case, you would aslo benefit to a certain extent from a silent conputer, if you don ‘t have one already. Adding a pi or sparky (i would go with the sparky If ethernet is to be used) to your setup, either as player, a upnp node or a roon node, should be beneficial. You would not need the usbridge as your high-end repeater plays the same role. Another possibility is to get an audiophile pci usb board from your computer if it’s a pc.

I get such a quiet background now and such sweet and resolved treble. Bass is also top notch. I am looking foward to observing variation or not from day to day with the grid’s noise varying,

Yes I get the same feeling with the 3R. Just goes to show the source is as important as the dac, if not more so, when it comes to impact on sound quality in the chain.

So all this talk about jumper settings got me curious enough take out my solder (and order some electrical bits) to make a quick test bench for DAC modes.



I've only tested for 30 mins, so no positive conclusion on what I like the most, but so far, the setting it is on now is what I am leaning towards (I think nos mode 2?)

Nos 2 sounds great indeed. My favorite along with os8, but nos2 is more forgiving to the transport.

That’s a cool test bench! I too have settled on NOS2 as my favourite setting. Its so lively and dynamic.

How would you differentiate NOS 1, 2 and 3? Most people seem to prefer NOS 3. What would you say is better about NOS 2? Just curious.

I found that NOS3 lacked some punch, which is provided by nos2. Haven't tried nos1 lately.

That said, nos3 is overall more refined. I am now using os8, in fact since i improved my transport (rpi) by adding a lps. I don't find it lacks anything.

Hey guys, just curious what everyone is using to connect their sources to the R-28? USB, I2S, Coax, Optical? And why? I’m currently running USB via a regenerator/reclocker and very happy with the results, but as always wondering if there’s a ‘better’ option (for reasonable cost, of course).

Hello folks,

I don't have the R-28, but I have a very close relative - AudioGD's R2R-R1 and NFB1-AMP, linked via ACSS. My R1 has the upgraded TXCO clocks option.

...

I run PC USB-> IFi Galvanic 3.0 -> R2R-R1. Got rid of any USB/PC power related noise, worth the investment in the iFi gadget.

Hi, everyone,

If I want to set NOS3 mode - do I have to switch on (activate) jumpers S1 and S4 (and for NOS2 - S1 and S5)? Is that correct?

What is second Mode 3 in NOS section? See the screenshot: https://drive.google.com/file/d/1WMQkJOQ7DDlfIwY40CIqxK04xqFVih3Z/view?usp=sharing

Both are the same NOS3, there is no difference. Kingwa mapped the same mode to two jumper configurations

Thank you.

What is another NOS mode when jumpers S3, S& and S6 are active? See the screenshot: https://www.dropbox.com/s/g0flbvh8uryzwjf/NOS 0.JPG?dl=0
