This may not be audible, but would be with a larger value like 250K or 1 Meg.
My setup was SY's HMN -> 100K TKD -> TSE. I paralleled 15K with the each channel at the attenuator to drop it to ~10K, as noted above. At 3/4 volume, shorting the resistors in and out, I could easily hear the highs were attenuated with 100K vs. 10K.

Thank you JP.

Makes me feel the 25K will likely be fine and the 'fixes' they post give me a chance to attenuate it if necessary to become a 10k.

My post was in response to George that the high frequency attenuation from 100K was something I could hear - he said it may not be audible.

You'll be dandy with 25K - there wouldn't be any need to go lower with the TSE.
