Expansion Dac static and noise

I just hooked up my v3pro with the expansion dac board and get distortion and noise. I can correct it by holding the cable that goes between the 2 boards.

Anyone seen anything like this?

@Napalmcsr Craig,

I have had 2 DAC extension boards and no problem with either.

It seems to me that by grabbing the cable you are providing an earth for the noise. Have a look at this post

I read that one before I posted,
I have tried:

Using the line out.
A different power supply
A different amplifier
A different set of cables
A different up2stream using the dac

All of them have static.

I then tested the different up2stream line out. It is perfect.

Statistically, I am wondering if I hit the jackpot and got a bad dac and up2stream.

@Napalmcsr Craig,

The only thing left I can think of is:

What happens in a different physical location (if possible) :roll_eyes:

However Arylic are very proactive and responsive. I am sure they will help you establish if you have faulty hardware :slight_smile:

No luck in another room on another app… I will wait to see what aryilic says.
Thanks for the help!

Try to disconnect the SPDIF cable, be sure no power cable is crossing over or under the cable.
It can all conflict with I2S.
For the SPDIF cable: Simply lift up the lip of the connector with a knife or smal flat screwdriver and pull out the cable.
No need to cut the wire. :wink:

The same thing happened with my pro v3 and dac board, the distortion was horrible, I had to fix it by shielding the entire cable end to end with aluminum tape. With the shielded cable it sounds incredibly clean.

Yeah, Arylic had me do that. Fixed it!
