Interestingly, for me the installed pads were hybrid lambskin with suede inside, I believe these are going to be the stock pads for Caldera Closed too:
Lambskin Deep were in the box as the secondary pads, these are slightly deeper than the hybrid pads and allow more of that ethereal feeling in the upper mids with ~1-2 dB lower bass at most:
The BOKEH protein pads came with the BOKEH demo so I thought it was meant for that until Zach mentioned otherwise (these are probably going to get a name change to avoid confusion), I have not finished testing them just yet.
