Low ESR Capacitor affected by Attenuator?

[Arno Pf]

So...what would the difference be that caused the significant audible effect?

The simplest explanation would be value differences between the parts, leading to changes in freq response. That can be quite audible. These large caps often have tolerances of 10% or more. That's why I asked about that.

Would be great to see results of similar trials switching blind between component A and B

So, the mystery remains.
Opening a can of worms about sound differences in capacitors is in the view...

Effect of ESR on the frequency response between bipolar electrolytic and MKP capacitors (with the same cap. values) is small but measurable. And possible to hear.

You know, you can simulate this quite easily with XSim.
