Noise (high freq) when tracking, why and how to get rid of it?

Hello,
In short, Here is a wav file with the noise i have recorded, did it ever happen to you, is there a solution for this?

My chain is a vintage u87-->bae dmp 1073-->la2a--->apogee element-->imac pro running Cubase 10.

1st I thought it was because of the Amphion amp in the rack so I turned it off but the issue remained.
Then I tried pushing the power strip further from the preamp because I thought maybe some electrical saturation was present.
Only when I turned off the phantom power and turned back on the noise disappeared only to return 2 min later.

Thanks for helping.

Just right click and download.
The sample rate is 88.2 on both Cubase and the converter.

Than what would 'clicking (too?) mean? (Suggests 'clocking to me.

player still doesn't run and shows volume muted
Does that (this) player even do 88k?

I haven't listened, but here's a troubleshooting tip: simplify your chain first!

Plug your U87 into your Apogee Element's built-in mic pre, run a test. Any noise? Yes? Try a different mic. Any noise? No? U87 needs to be looked at.

Rinse and repeat down the line, swapping cables too.

Yup, was just wondering if someone heard this specific noise before and could save me the test.
I am currently checking to see if this is a feedback sound because it seems that whenever I sing it disappears...

take that compressor out...that's what it sounds like

edit: sounds like you have boatloads of compression so it's bringing up your noise floor when no signal is present. As soon as you sing it kicks in so noise goes away

With all due respect, with that amount of money tied up into your signal chain, you could really stand to learn from this and actually go through the troubleshooting process for yourself.

I once had something similar happen to several takes that I did on a film set when I was using the phantom power on a location recorder. It turns out it was the phantom power was somehow noisy. Came down to a design flaw in the equipment.

I know nothing about the Apogee Element. But I would first try plugging straight into it and using it with and without phantom power in an effort to narrow down what the culprit might be. Then I'd add one piece of equipment at a time to the chain with and without phantom power.
