Okay thanks What about using the isolator board with sparky and USBridge

Hi Wanted to know if I can use the Allo battery pack to power the USBridge HAT? The sparky would be powered separately Also will using the isolator board with the USBridge HAT give any improvements? TIA

Finally managed to make USB cable with no voltage + connection with the help of a close friend who is very good with making cables For me it surely sounds better then before, can hear more into the music The difference again is not night and day but enough to hear a difference

Cut the + 5v and DAC gets detected perfectly. No issues So now I at least know with my DAC I need the ground to be connected for the DAC to be detected by host PC Thanks again for your help

Thanks @mansr and others I will do as advised and update on the thread

First of all thanks for your reply My DAC has cmedia cm6631a USB interface so it's a USB 2 high speed So I will try to experiment connecting ground with DC male and female pins so I can disconnect it later on How can I connect only 5 volt plus to any external PSU? TIA

Tried connecting voltage + and - to an LPSU but still DAC is not detected Need to connect the USB header having voltage + and - to PC , then only DAC gets detected Not sure what to make of this

I disconnected the 5volt + line and everything worked fine but the moment 5 volt (-) is disconnected the dac is disconnected from windows So does that mean dac needs to see a ground to function? Sorry for asking another dumb question, what happens when the laptop is running by battery and power brick completely disconnected ? Is there no ground to the laptop?

Thank you guys I will use a LPSU to give 5 volt feed. That for now looks most sensible option

I made my current USB cable into a dual headed USB cable with the help of my friend One connector has the Data + and - connections and other Voltage and its ground But the moment i remove the connector carrying voltage my DAC is disconnected from windows. So does that mean my DAC needs constant voltage even after hand shake? My DAC is a Burson Conductor having a C-Media USB interface Or is it that i just have to disconnect the voltage ground, but even doing that will make the circuit incomplete I am a little confused so want help from members who have tried this trick Will it be a good idea to connect the second USB connector carrying voltage and its ground to a linear power supply ? Lastly with this modification is a USB regenerator / reclocker like Uptone / W4S recovery advised to be used between PC and DAC? TIA

What are the resolutions it supports?

What is the recommended power supply to be used ? And can the dac baord be powered separately I had read Allo is also designing a LPS Is it true?

Thank you so much sir for making us understand the technicalities It was surely an eye opener for me So the preferred connection should ideally be the network input for streaming of data with the way it's implemented

Sorry did not read question properly before The NB I think has no usb input for audio so ethernet is the best way to make it work it with the innous
