Do you know what is the Audeze LCD-3 pads outer diameter? I could perhaps try them with a more shallow pad, but need the dimensions. Also, the inner diameter is important. I wonder if the Stax 009 pads would fit (107.5 mm outer diameter, 31.5 mm high at the back and 18 mm in the front). My current pads on the 007 are 104 mm diameter, 18 mm high in the back and 15 mm in the front.
Oh I thought you had LCD3 ?, I sold all my audeze so can't tell but I bought LCD3 black vegan pads for HE6.
When I get back home I can measure it for you.
