If one needs additional power depends on other devices sharing the same hub (also internal). Always connect a sc the shortest way as usb hubs don't have QoS options.
You better put an external power to an external hdd as this is high power device. Also less chance of the adapter having influence to the audio.
A power problem does match to at least part of your problem. If you have the proper equipment you may want to check if your wall socket has the right voltage. More difficult would be to check the current. Are you using clean power or are other devices causing power dips. Like dimmer, dishwasher, light show, ac, heater etc
It may be - but this happening in a lot of different locations. At las gig it was just big gym with two stereo speakers and my set up.
At home I got turntable in one room where is only one desktop PC in same room. No other devices. I got also another cable for u46mk2 and on 99,9% problem is not in cables, it cant be cartridge and i guess its not even computer problem since I have exactly same problem on win and iOS.
BTW : Merry XMASS guys - thx for input and I am patiently waiting for analysis:)
