Just wanted to post some measurements of the Clear from the GRAS rig:
This is relative to the Harman Hybrid target I’ve been going with for now. It uses the 2013 bass but the 2018 mids and treble. I like this target the best so far, even though it still rolls off a bit in the treble.
Here’s the channel matching for L+R
Here’s the Clear vs Harman2018 with linear bass below 900hz.
Note that the 9khz dip is supposedly due to concha reflection. Apparently this doesn’t show up on all headphones, but it does on ones with a lot of interaction with the physical ear.
