I’d say they sit between Audeze and Hifiman in terms of sound signature. They don’t have quite the same slam and rich creaminess of Audeze, but they have better treble extension, but they’re not thin/bright/anemic like the Hifiman house sound, and don’t sound ‘far away’.
I’ll add the caveat that my impressions are with EQ as I found them somewhat disappointing without it, but they sound amazing with it.
If you’re not going to EQ the velour pads are the best bet - they’re mid-centric with those with sub-bass roll off, but they avoid the midrange dip that you get with the leather pads without EQ.
With EQ the leather pads dog deep into the sub bass and have a nice well rounded FR going up with plenty of bite and intensity.
Compared to the LCD-X, both EQ’d, the LCD-X is the better headphone, but it’s not multiple-times-the-price better.
