Music stumbling with Audiophonics ES9028Q2M.

Message par maccarry » mar. 07 nov. 2017 08:04

Hi.

I’d like to know if someone has the same problem as me.

Recently I bought a Audiophonics ES9028Q2M. But I’ve problems playing music through it.

When a 192KHz 24b is played, music stumbling. And the display alternatively shows 192K and Unlocked. Play 44,1KHz 16b is a little bit better. Sound is good, but display alternatively show 44,1KHz and 48KHz.

I send the DAC to Audiphonics, great service, and they change me the DAC for a new one. But the problem still remains.

The fact is I’ve tested with a Raspberry 2 and a Raspberry 3 with and without Kali reclocker. With Volumio 2.31, Rune audio 0.4 Beta and with Moode Audio 3.8.4 with same results.

The ES9028Q2M is not the only one DAC I have. I also have a Audiophonics ES9018K2M, a Mamboberry LS DAC+ and a Allo Piano 2.1. All of them plays 192KHz 24b flawlessly, without any trouble and with the same hardware and software.

The question is, does any one an idea on where can be my problem with the DAC?

Thank you in advance.

Hi,

If Kali Reclocker is installed, I use a 5V 10A power supply to power all components through the Kali module. Without Kali I use two 5V 2.5A to power each component, one for Dac and other for Raspberry.

Regards.

Is the problem the same without Kali and the smaller PSU ?
