Empirical audio off ramp turbo I2S noise

Recently I install in my system a passive preamp that Im really happy with. The problem that I have is that if I use my off ramp turbo to convert usb to I2S that goes to my PT P3A, the preamp is picking up some noise from the off ramp, as soon as I unplug the I2S cable from the P3A noise disapears. If I use m2tech hiface usb to digital and the the P3A there is no noise at all.
Would like to know if other people found same issues or if someone have an explanation for that.

Yes Steve is the turbo mod. The problem is only there if I use a passive amp, not a regular one, in that case is dead silence. The I2S cable is the one that you provides me with the package.

Thanks Steve. Yes, all are connected to the same circuit. One thing that maybe is usefull is that the noise is not volume dependant: doesnt matter if I rise or lower the volume the noise is always at the same level.

Problem solved, was a computer issue, no the devices.
