Jens, are you able to specify each voltage rail and current draw? Would be good to work with the correct information from the start.
Fired up my RTX6001 for the first time in a while, and on a new PC. Somehow the loopback results are not as I recall, can someone please confirm? Both input & output channels perform identically. The crosstalk mod has been applied but that was before the PC switch.
FS=48kHz, Vout=1V, Vin=3.16V, calibration for 0dBFS = 3160mV.

Yes, same result with ASIO and DirectSound. Just confirmed the same results with a different PC.
I can't see the capture clearly, it's too small on my laptop, but those numbers don't look too different from what I recall seeing on my RTX at those levels.
Try about 3dB lower output level and see what you get.
Also sometimes I use the next input range up as long as noise floor is still acceptable.

Could you try with my "standard" setup:
Loop-back from left generator output to left input and right generator output to right input.
Outputs set to 20 dBV.
Inputs set to 10 dBV.
Setup used in audioTester:
Sample rate: 192 kHz
1 kHz tone at -20 dBFS
FFT =512k, average over 10
Then you should get a resuslt similar to the one attached, which was made on your unit as part of the final test..

This looks like the idle currents. Additional current must be available for high level outputs with low impedance output load, potentially short circuit outputs.
The available supplies should be someting like this:
+18 V @ 750 mA
+9 V @ 250 mA
-18 V @ 600 mA
These are minimum voltages to ensure that on-board regulators will still work. Higher voltages will increase the power consumption and heat dissipation. With the original tranformer + rectifier the unregulated voltages are of course well above the values shown above.
Lower voltages may degrade performance and eventually lead to malfunction.
Thank you Jens.
Is the +18 VDC supply a quiet one, or just for control and house keeping? The bipolar 18 VDC rails are obviously low noise.

The +/- 18 V DC are used, among other things, to supply some on-board +/- 15 V regulators, supplying the op-amps etc. They don't have to be super quiet.
The +9 V supplies the ADC, DAC logic etc. through a series of regulators.

The sale has ended. Probably didn't pay off. Although there was a market. At the moment, however, there would be problems because the AKM factory cannot deliver.
Virtins still offers a package for $2495 which includes the RTX-6001 analyzer and the software required to run it, here: https://www.virtins.com/RTX6001.shtml
I have one, it's very good.

The Virtins software is not required to run the RTX-6001 in any way. You can use any software that works with a soundcard.
