If you want to try a few more pads now’s the time to do it. I’ve never figured out why my B-stock pads are B-stock. Sale is until the 10th.So I guess I shouldn't be so quick to sell my Aeolus (Sepele) when my Auteur (Blackwood) arrives. Also I never thought of putting pads for other ZMF cans on the Aeolus. I have the perforated suede on them now.
Does the type of wood change the sound of the headphone?
There are several discussions in multiple threads about how wood hardness can alter the sound slightly. The consensus seems to be pad rolling has a much greater effect. Search “janka”, the wood hardness scale, and you should find a few of the discussions. There are people with multiples of the same model in different woods (or stabilized) that can compare directly. Or maybe you can make it to a show sometime and hear for yourself.
