Hello hello,
I had for some time in my setup a DAC (Gustard X16), some active Neumann speakers (KH80) and additionally an Audio Technica turntable (AT-LP60). I recently purchased a headphones pre-amplifier (Gustard H16) along with some audio headphones to enjoy more peacefully my music.
However, while setting up all of this, I was faced for the first time with static noise in my monitors when no source is playing. Upon playing something through the DAC or the turntable I am also now getting very poor sound quality and a lot of crackling, with the monitors or with the headphones being the same. I made a lot of tests to try to pin down the problem: unplugged everything but the preamp and the monitors or the headphones, with and without DAC, without the source selector, trying with the turntable and so on but no chance so far.. I further tried to change the power socket in which the preamp is plugged (for now everything is on the same multi power socket) but to no avail.. I am kind of running out of options of things to try and I am really confused if I actually plugged something the wrong way.. I did some additional tests to figure out the gain settings but it did not yield any improvements.
Details of how everything is connected:
Turntable AT-LP60 / DAC Gustard X16 -> RCA -> Source selector Dynavox AUX-S -> RCA -> Preamp Gustard H16 -> Headphones AKG / Active speakers Neumann KH80 with XLR
Turntable on Line setting, DAC on 0dB, Preamp gain Low/Mid/High, Active speakers on 0dB input and minimum output (84 dB)
I hope somebody can help me figure it out!
Cheers!
