Is it just me or is this one of the cleanest and straightest CSDs here? Sure there are a few minor ridges here and there, and there is a slight low-end emphasis, but it's almost flat all the way through and decay is consistently <1ms all across, in a closed headphone too. Am I missing something here?
Edit: huh apparently the right cup is a bit nastier in terms of ringing, but theoretically a "better matched" pair would be like the left cup on both channels. Also the right cup measurement is even flatter across 500-20000Hz.
