Help needed to eliminate unwanted noise from tweeter

Hi all, need your advise to eliminate annoyance "sizzling" noise from speakers' tweeters (close listening range).

I have isolated all the power supply of audio equipment. Then plug in one by one in sequence as following: -

a) Integrated Amplifier - Accuphase E280

b) CD Player - Sony CDP-997 (standby power) - no noise observed from tweeters even my amplifier volume knob is at set to lowest position.

c) DAC - Denafrip Ares II (standby power) - Once I plug in, I could hear the sizzling noise from tweeters when my ear is near speaker.

d) Music streamer - Unplug Ares II, and plug in Eversolo DMP A6, similarly I could hear noise from tweeters.

From the above, could someone pointed me what's wrong with these two (2) units? They are three-prong with ground pin, they are connected to my Novaris Surge Protector multi-gang socket outlet and to wall recepatacle, there's earth/ground continuity.  

Your advise will help me to isolate the 'noise' issue for cleaner auditioning with thanks.

Regards,

Auronthas

Try different XLR cables with the units causing the buzz/noise. If that doesn’t fix it, I would suspect your internet connection next. Sometimes they are noisy. Have you tried wired and WIFI to see if it makes a difference (if you have a Wi-Fi receiver) that you can connect to with a short ethernet cable to the rear of you unit?

The only other things I can think of is to try to connect the noisy components to the input of the E280 and CDP-997 where you know there’s no noise. Also, if there’s enough slack on your cables and wires try holding the noisy component in your hands and moving it around in the air. Maybe it’s too close to a transformer of another component. Maybe the component itself is the culprit? Try distancing/ separating power cables and audio cables (don’t bunch them together. Has this noise always been there? Did you change something recently? Is the noise less at night than during the day? Have you tried a different outlet? If the problem comes from your house wiring you might need an AC voltage regenerator, but they can get very expensive (thousands). This is the only sure way to get rid of any AC noise. A surge protector or filter WILL NOT eliminate noise from your house wiring.
