If you pause the song and turn the volume knob to 2 o'clock, do you hear a hum? Check by touching the knob with your fingers.

I connected my notebook on battery and the static went away, so there might yet be some interference going on. At least I can assume now that the device is not defect in some way.

However, my Chord Qutest order just arrived, and I must say that this DAC has the Violectric DAC comfortably beat. Dynamics, detail, sound stage, layering and, best of all, no noise! My endgame combination may just be complete right now...

I had a Topping D90 MQA lying around, but preferred the internal Violectric DAC, not because of capability, but because of character. The Topping is the brighter DAC, and sounded harsher connected to the 590 compared to internal DAC. I would rate both DACs to be of similar quality otherwise.

I thought it was a mass noise, due to the potentiometer which is not connected perfectly.
My advice is to put a copper flat washer on the potentiometer shaft and tighten the nut (by hand) with a good amount of force.
If the potentiometer makes good contact with the chassis, the noise disappears.

Wouldn't that mean that I would hear noise on all inputs? I had static with the digital inputs only...

Test your connections without coverage..

greetings how does the 590 hold against newer amps such as enleum or holo audio bliss

Haven't heard the Holo so no comment on that. The Enleum (and it's Bakoon predecessor) are... different. Not necessarily better or worse imho, just very different sounding amps. I can see why some people absolutely fall in love with them, but I can also see why they just sound off for some people as well. Very difficult comparison imho.

Honestly all three seem like well designed amps with plenty of power so it would come down to what headphones are being driven and what your tonal preferences are.

this setting keeps the line output at 0db, (pre amp off)and the headphone preamp at preamp +18db, right? because in the manual the position of the switches is exactly the opposite, which is wrong. The first picture is my setting and the second is MANUAL.

In the photo from the instructions, the shaded square is the cap of the dip switch.
Your gain of +18 dB is set strictly in accordance with the instructions.

so my current setting is the pre amp of the line output is 0 dB and the pre amp of the headphone amplifier is currently set to + 18 dB for me, as shown in the picture, right?

I really don't understand something... as it turned out in the past few days, because I misinterpreted the manual, the output of the dac line was all turned on, in the above position, because I thought it was turned off, but a few days ago it turned out that it was turned on... actually, now my problem is the fact that I turned them all off, so the preamp is turned off at the moment, and my active speakers, which are on the xl output, started humming... and it never hummed before, it didn't make any noise... how is this possible? and if we set all the switches in the program to the above position, i.e. on, what actually happens??? because the MANUAL does not write anything about this. there can be no ground loop because it was not connected to any of the power distributors, nor was it connected to any of the power cables.. I am sure that this phenomenon depends on the setting of the preamp... I just can't understand that since they are all switched off now, it is in off mode and right now my system is behaving badly... here is a picture of the current setup.

Hi.
I have a question about gain operation.
I use meze109, but when I auditioned V590, it was around 8 o'clock with gain 0.
I know I can go down to -18, but if I enable -18 and -6 and go to -24, will the volume go down further?

I have both 590 and Enleum. I would say if you have Susvara, then go with Enleum. The sound that 590 produces is too soft for me. Enleum also drives LCD-5 quite well.
