Hi Alex:
I appreciate your report! I have a few questions, though:

Are you saying that you used both the pads and the resistors together? Did you try them individually and, if so, what were the results?

Did you notice a loss of detail in the highs, or was it just a matter of reducing the sibilance you were hearing and leaving the detail intact?

How did you attach the felt? Is it something that was easily removed?
