the app gives a view of the Chu2 presets PEQs
Forgot to add a point about the presets: they (can) represent the manufacturer take on their own product. In the case of Chu2, an entry level IEM, three of the filters are the same across each preset, the other twos are about preferred bass level. It gives a good indication of what Moondrop “wishes” the Chu2 to sound like… if they had no design/cost constraints whatsoever.
I personally find interesting exploring these preset filters: hearing what difference they make (or not !!!), what are they correcting or filtering out (a narrow distortion as seen on the Tanchjim One), and generally playing around a little, to better understand what difference I can or can’t hear, what is it that I truly like and dislike. That’s what I do with the similar Tanchjim One, Zero, and Tanya entry-level DSP IEMs.
I wish Moondrop would provide these preset filters for MAY. Yes, they can be inferred from FR measurements… But, MAY is a pretty damn good sounding IEM, and I would love to know details (what PEQ filters) Moondrop would suggest to further improve or tailor MAY to one hearing capabilities and tastes.
That’ll be so much more humble and constructive than claiming that the
“newly developed sapphire-evaporation composite flexible-suspension diaphragm reproduces classic beautiful timbre, providing wide-band smooth response and ultra-low distortion of fasts transients” (cited from Moondrop MAY web page). Oh well… I’ll continue with my sweet dreams
