I would try an cheap/used or lent Low MC .
It was not designed for high output carts but it works wondefully with a DL160 with 1.6mv output, so that does not seem to be the problem.
Testing a Low MC could isolate the problem .
Maybe 1.6mV is OK , 2mV is too much ?

2mV at the input of the Paradise gives somewhat more then 2V at the output.
The only thing that goes down is overload margin. Say there is a music peak cut at plus 20dB ( x 10 ). The paradise will put out 20V but that is at the edge of what it can handle.
This will only happen on a few extreme records, say from RR or Telarc.
I whould say a cart with 2mV at 5cm-sec is the maximum i would use with the Paradise.

If you have a fast true RMS meter you could put it behind the Paradise and measure with a
very dynamic record what actually happens. You can also put a scope there.
Overloading the Paradise is unlikely but what will your power amp do with 20V P-P input ?
You really need an attenuator behind the Paradise in those cases.

wav is cool.
If we listen to it we might identify the problem
Hi, I made the files, but cant attach them.
UUHH, that was difficult. But here they are. I have only 1 side (right chanal) so you hear only the voice.
"original" is the part of the grenn apple limited edition directly from apple records digial remastered
"Paradise" is the part of a MFSL Abbey Road album nearly new (one time played), Benz mirco silver 2g Tracking force, input Paradise: 2,7nF bridged with 1,2kOhm.
Do you need further information?
The tracks are very short so it is difficult to judge.
Do you mean 2.zip is a digital file ?
In the 1.zip, comming from the paradise I do not notice any "electronics nasties"... What is your TT / Arm combo ?
I would look at VTA / Antiskating / VTF.
VTA is determinant in Benz carts.
PS:
The Benz micro silver always had a somehow coarse high freq response IMO.... I sold mine because of that.

Yes you are right 1.zip is Paradise and 2.zip the digital.
My turntable is a Dual 1019, nearly original, but the tonearm is carbon.
VTA is unadjustble, it´s fixed
Antiskating is 2 as recommended with 2g tracking force.
VTF 2g
I had an tube-phono-pre before, but can´t remember any harshness like this.
But I am realy a novice in turntables so it could be a missadjusting.
Maybe your tube phono was hiding some high freq detail.... or your riaa caps are not perfectly dimensioned.
Did you measure the riaa caps before building ?
What is the value of the 11nF caps ? These are the high freq cap and a very small difference from spec can cause really nasty high freq peaks.
