I spend a long time on sound quality of this unit . Many PCB revisions.
My model is to test for everything and any deviation (noise) as long as I can measure its fair game (Bruno P. quote) while I will not comment if you can hear it.
Now sound quality has an subjective side. I did my best to incorporate audiophile "myths " into the unit and the result was (for most of the times) a clear reduction in H. Some changes (like RFI removal) were very slightly visible in the AP but clearly very audible.
I also incorporated work from Rasmussen / Abraxalito (IV pre filter) but I used my own schematics and tests
At last ,,, I want to clearly say that low impedance power supply is one of the important aspects of Rev . Now only we used lots of lytics on the PCB , but also we used a lot of supercaps in AVcc (Rasmussen/ Ians pioneering work) and many subjective impression point to the massive importance of having enough electrons on board (especially for Avcc and opamps)
Revolution Dac is made for audiophiles , but not against THD. Who said that great THD means low SQ ?
Congratulations,
do you provide a USB cable solution for Rev so it can be powered completely via USB Vbus without additional power supply?
Thanks
Matt

Was wondering this too
See power/audio-in/audio-out connections for the Rev DACBTW not sure if asked already but does the DAC require power over USB? or can it work with only data (vbus cut)

Damn I would love to see what you can do with the new AKM chip, with a higher budget around the 500-700$ class
Though just to buy the chip costs $ 70
Topping, Gustard and SMSL all have DAC's using this chip.
The pre-order page for the Rev is up: Revolution DAC
Hi this is good news
I have order the revolution.
Kind regards,
Ben 😉
we are releasing a cable (its actualy made in flex PCB) that can connect the USbridge to Rev Dac
This flex PCB has controlled impedance ..(better than any cable)
Rev needs less than 400ma..so 1A its plenty of power
Hi,
I have a question about my usb cable now
Now can I not used my usb cable from usb bridge signature to the Revolution dac... 😀
The revolution dac used a other usb in.
Where can I order this cable..
Kind regards,
Ben 😉

Sorry but we still dont have the cable , we will get it in about 1 month
We do not recommend it for best audio performance
Typo ??
Thank youThough.
Typo ??
Ooh I have not read about the cable
I see it...
Now I must see how I can make it right for me.
I use a Tellurium Q Black USB Cable.
I go see of i can find a other cable for this..

Revolution has 2 inputs...DC barrel for power and USB input for data
Please note that both inputs feature specific filtering to remove the influence of power and DATA source (and while its doing a good job , a better source means always a better sound in subjective impression )
Using a USB cable (split) for USB data and power (with DC barrel adapter) is not recommended for SQ

Hi cdsgames,
I can use DC power in my shanti dual psu.
And only I see for audio(data) in... revolution used a (mini) USB c?
Than I must I use a other cable see to found for that (AudioQuest)
Only I found my telerium usb better only it is usb type a to type b cable.
We go see it as the revolution arrives in juni

Signal input on the Rev.DAC is USB micro B.
The new ribbon cable from Allo is for this, will not cost anything like a Tellerium Q Black.
You could send it to me to test as my DAC has a USB B input. I'll pay you for the Allo cable
The Shanti is the perfect power source.

Yes Shanti is perfect
Any news on the slightly less perfect Nirvana?
