Pioneer DDJ-SZ/DJM-900NXS white noise

I recently spent quite few dollars and upgraded my trusty DJM-800 mixer (which I use it for studio recordings) to a Pioneer DDJ-SZ controller and DJM-900NXS mixer.

While performing basic sound tests, I noticed a major issue on both new products: there is an incredible high level of white noise outputting into my Dynaudio BM6 mkIII monitors. I have ZERO issues with the DJM-800. My test routine was simple, I plugged the supplied power cable into a properly grounded socket and used a pair of 10 feet Mogami balanced cables connected straight to monitors from Booth Out, with no other cables or inputs used. Once I turned on the speakers, the white noise was there.

Does anyone else experiences same issue with high-end monitors?

I made a quick demo with the DDJ-SZ, I have the same results with DJM-900NXS probably because both products share a lot of similar components. I made an exception and left the speakers on during the unit power cycle, to show exactly when the white noise kicks in:

For some reason, my cell phone video recorder is filtering out the white noise after 2 seconds, it is there always.

I'm really disappointed, as I already sold my DJM-800 and I'm stuck with these products which will not allow me to properly record my music.
