Did you try with laptop not plugged to the ac cable?Mmm is it a problem of the DAC or my laptop? Cause using the phone is quiet.
The idea of disconnecting the laptop supply was to confirm a ground loop. The monitor disconnect suppressing the noise confirms it further.So, I've tried unplugging the laptop and it helped, but what really killed the hum was unplugging the HDMI cable to my monitor.
Are these types of issues with noise due to the DAC or to the laptop? I mean, would a better DAC be quieter plugged to my powered laptop?

Do your speakers have xlr inputs?
If plugging everything on the same AC plug doesn't work, try RCA to XLR cables.They do. But the DAC only had unbalanced out
Well, if you ask questions without reading the replies, problem solving will be tough.So, I run a few tests.
It's all the HDMI cable to the monitor. I can plug laptop, speakers and DAC to different power plugs, it's all quite up until I plug the HDMI from the monitor to my laptop. I tried with the monitor in the same power plug, no difference. Still noisy.
It's kind of a big deal, because if I want to watch movies or youtube on the big screen, I get crappy sound from the speaker.
Do you guys know why HDMI creates this noise?
Thank again!
Actually, you need to add the DAC and the speakers in the loop. Else you wouldn't care.Actually, I see now the loop: plug -> monitor -> laptop -> plug.
Did you unplug something that was connected to the same electrical line (so on the same breaker) ?Now the noise has gone! Even with HDMI in. I haven't touch anything... I'm amazed and confused.
It has to be the original version if he didn't explicitly say it's mk2. Simple logic.Hi,
Are there anyway to differentiate the mk2 version and the original ? Some guy offer a Sanskrit to me secondhand but I'm not sure if that it is the 4490 version or the 4493 version.
Thank.
He said that it is the mk2 but didn't have the box or anything, the price a little bit low so I'm tempted to buy it replacing my M100 .It has to be the original version if he didn't explicitly say it's mk2. Simple logic.
