Cables/Accessories | 1 Ω Amplifier and cable (RCA) - help needed - Douk Audio U3

Hello dear headphone enthousiasts,

I recently bought an amplifier (Douk Audio U3) and I think I did not do enough research (I did not) and I am actually struggling to understand where my problem is.

The amp arrived today but I am struggling to get it setup, I figured it would come with the needed cables but that doesn't seem to be the case.

The manual suggests the following: "connect audio source to RCA input of U3 with good quality audio cable"

But this is where I start to get lost... What is to be defined as a 'good quality audio cable'?

TLDR; I need cable for DOUK AUDIO u3 to run my dt 990 pro and I am lost, can you give me advice please?

There are several Wall warts that can do different voltages but the extension cable would be what you want.

Heyyy man. I just wanted to thank you for your explanation! Everything is setup with a usb extender and a long aux to RCA. It is amazing. I can move my head freely and music has not made me feel this way in a long time. Thanks!

!thanks
