Was working fine through yesterday. This is a brand new unit. I’m not really confident in the hardware and I am not interested in a repair so soon.

Will you please advise on a replacement for a new unit?

Hi @Joe_Serpa1,

Apologies for the trouble here! So we can help you would you kindly verify the following:

  • What was the date the Nucleus was purchased?
  • What is the Serial Number of the device (this can be found on the bottom of the device)?
  • Are you using the power supply that came with the device?
  • Have you discussed this with Woo Audio? We might need to do some advanced troubleshooting to understand where this issue is stemming from and we’d be happy to work directly with them to get this resolved for you.



Purchased 22 Jan 2020. Delivered 28 Jan. Tracking 150767920941 Fedex.

Serial no.: 54B2038B9A30

I am using the power supply that came with the device,

I emailed Woo Audio today. No response yet.

I have owned the device for three weeks, one of which I was away. I hope you understand that I have little patience for advanced troubleshooting on a new device that is not functioning at all after little use.


Hello @Joe_Serpa1,

I spoke with the hardware team and they let me know they’re working directly with your dealer on this.
If you have any questions just let us know, but Woo Audio should be able to help from here.
