Other variant, I think this one is better:

To my ears there’s a slight blurring of the percussion sounds, suggesting phase changes?

Thank you. No phase changes, just spectral manipulation. Now I am busy with the other method, I'll show it when it is ready.

The results are subtle.

i don't know what processing you do exactly, but both processed examples sound far worse than the original.

It's hard for me tho describe the first method, but the second one is connected with echo signals.

As you can see on the spectrum an echo signal is the small copy of the main signal. Now I try to filter out the echos, which move closely to the signal. First whe must find the direction of the echo, then we use spectral masking. Here the distance is 6 bins. I made an assumption that short echo signals are connected with ADC, which is not perfect.

I am developing an audio retouch program
