Does the quality of a power cord makes any difference?

Yes it does. I have tried both a "standard" power cable and compared it to a 9 AWG, shielded one and the result is significant.
The quality of the sound improves quite a lot and the last thing to add is a good fuse to make the best of it.

Yes, it is the recommended value for the nano fuse from Gustard for the U18.

Who is using the Gustard U18 with Rockna Wavelight via I2S connection? sound great but issue to play audio files with Sample rate 96/24 and 192/24 using Gustard I2s Pinout and PsAudio Pinout. same issue.

Any idea how to fix?

Should I connect the U18 to a USB 2.0 or 3.x port on the PC?

I use the SOtM sMS200 Ultra =>Gustard U18 =>I2S=>Rockna Wavelight. The Interface receive the correct sample rate but looks like he lost connection after half second on I2s connection.

USB 2.0 is fine. Plenty of throughput for streaming audio. What is of more importance is to use the best quality USB cable within your budget.

I'm sorry but what do u mean by adding a good fuse? I need to open the case and solder something in?

Thank you.

High quality gears are usually very sensitive to the choice of fuse. The U18 responds very well to silver based fuses. It is all about to balance the sound to Your preferences.
If You are pleased with what You have. Don't change anything.

The fuse is located in the power cable input. It is a 5x20mm fuse. You can pull out the fuse holder with a small screwdriver (slits marked red)

VERY Coold stuff. Seems like a easy tweak. Any chance u can share which are the silver fuses u tried that are good?

There are relatively cheap Aucharm fuses on Ali-express You can try.

Link didn't work. Just search for Aucharm Fuses

What's the Ampere of the the fuse that should be tried for U18?

 

[Matthew Willims]

500ma or 630ma. Currently I prefer the Gustard branded fuses as I’ve a little too much silver in my system already. I’ve Hi-Fi Tuning Silver & Gold + Synergistic Research Purple fuses on the way to try in mine though

Original fuse is 500mA/250V and Gustard recommend their own silver fuse on 630mA/250V. You may choose 500mA/250V or 1A/250V. Both will do the job but 500mA/250 is the safest choice for the protection of the electronics.
