    We're all getting old , 3.3 ohms can be written as 3r3, and 3.3k can be written 3k3.

    Your Passive pre is applying no amplification at all to the signal, it only attenuates.
    No one seems to have asked what your source is, to be such a miss match for your power amp. it sounds like a very hot digital source.
    What is it and what's it's output?
    Is it a DAC with a digital volume control that can be turned down?
    What is the input sensitivity of your power amp?
    Adding resistance to your Passive Pre, might be the solution, but alternatives, or even defining what the actual problem is, has not been given proper consideration.
