This is part of a vintage system that I am downsizing as I have 3 systems.

Happy to negotiate a bundle price for all Luxman components if there is interest to buy the TT, Tuner and Integrated in one lot.
I'm having an issue with an electrical buzzing noise coming out of the tweeters of my active monitors, I'm trying to determine the cause so I can fix it (ideally without having to resort to ground loop isolators).
On Monday I received a new JDS Labs Element II DAC/amp unit to replace my dying Audio GD NFB 15.32. The Element is USB only, where-as I was using an optical cable with the Audio GD. Upon changing over to the Element, I noticed a 'dirty' buzzing sound coming from the tweeters (JBL 305P MkIIs) that was not there before. This buzzing is totally independent of the volume pot on the Element or volume in Windows. It ceases when I switch to headphone output on the Element or when I turn my computer off.
Additionally, this buzzing behaviour is not present when I plug the Element II into other devices. I've tested it with two laptops (a dell and a macbook air) as well as my android phone.
The noise seems to correlate with system load (it becomes considerably more pronounced when running a game, sounding sort of like coil whine) but also changes in pitch when I move the mouse and takes on an even buzzier sound when I use the scroll-wheel.
I'm not electrically knowledgeable, so please enlighten me if I'm totally mislead on this, but if this buzzing was a regular good old fashioned ground loop issue, wouldn't it still occur even if I had the element plugged into a different source? FWIW; everything in my system is plugged into the one power-board, which is plugged into the wall via an extension cable.
I can only conclude, with my layman lack of knowledge and the process of elimination I've done so far, that it's an issue with my computer since it's fine with the laptops and phone. When I think about what could be wrong with my PC to cause this issue, my mind immediately goes to my power supply, which has made a buzzing noise when running since the day I bought it last year. Does it make any sense that a bad power supply might cause something like this? If it does, I'm strongly considering buying a new different PSU and cross my fingers that it fixes it. It's not too risky as I would return my current one anyway (I've just been too lazy to do so and it hasn't appeared to have caused or been related to any real issue until this).
Sorry for the wall of text, would appreciate any insight or thoughts on this!
tl;dr - Active speakers buzzing since getting JDS Element II. Buzzing seems to be correlated with PSU buzzing. Speakers do not buzz with other computers used as source.

Item Condition: 8/10 Shipping Options: Pickup available and you can audition.,Shipping is available at agreed cost. Suburb or Town: Tura Beach State: New South Wales Payment Method: PayPal friends, EFT, Cash on Pickup Reason for selling: Downsizing and rationalising Further information:
Classic hybrid MOSFET/valve amp from the early '90s. I have thoroughly checked it and run it having pulled it out from storage. All inputs work and all switches and knobs operate and are quiet. And it sounds wonderful ( tested on a pair of JBL L60T).
It comes with the instruction book (a little dog-eared) and original packaging (7/10 it has been doing it's job keeping the amp safe in transit and storage and shows some wear and tear).
The amp has a couple of cosmetic defects as shown in the photos - scratches on the top right side of the front panel, other minor blemishes, and a small chip out of the plastic shroud around a red speaker terminal. Hence I give it a 8/10 rating.
Power output: 105 watts per channel into 8Ω (stereo)
Frequency response: 20Hz to 20kHz
Total harmonic distortion: 0.008%
Input sensitivity: 0.15mV (MC), 2mV (MM), 150mV (line)
Signal to noise ratio: 70dB (MC), 90dB (MM), 110dB (line)
I am happy to ship with a little extra packaging. Seems to be about 80 within mainland Australia with insurance via Aussie Post. Happy to work with a nominated freight company as long as you pay.
