@renisnceman - WRT the hum
1. is the hum a 50/60 Hz mains hum? or is it higher or lower in frequency
2. is the hum a constant level?
3. or does it get louder as the volume is increased?
4. what speaker cables are you using?
Which model Jolida DAC do you have?
I see the STA200 is a power amp
- so I assume you are controlling the volume via the DAC - correct?
The microphonic effect - e.g. The cable from my turntable suffers a microphonic effect.
- i.e. I can hear sound if I tap the cable with my fingernail
- does this happen in your case?
- this can cause hum if in close proximity to other cables
Is the cable in question near a power cable or a component power supply?
One last thing to try - using a piece of wire, touch one end to the neutral side of the RCA socket the cable is plugged into and the other end to a "common ground point"
- does the hum go away?
- if yes, it may be because of the grounding design of the attached components and the geometry of one of the cables highlights this anomaly
Also, Cables can cause issues within attached components and sometimes it is another cable (e.g. speaker cables) in the system that causes the problem
- answers to all questions above will help get to the "root cause" of this problem
