Oh, yeah the LCD-5 is fairly mid-forward, hence those two elevations. I find myself saying this in a number of places already but like, even relative to the HD 650, the LCD-5 has fairly dark treble. So if you think the HD 650 is warmer than neutral, you’ll want a treble boost of some kind. But if you think it’s brighter than neutral - which I have yet to meet anyone who thinks that - then it would be fine. When it comes to the balance between fundamental and harmonic, however, the ear gain region is definitely a bit too pronounced there in relation to the rest of the treble, meaning that those tones around 3khz come across more strongly than their resonant harmonics.
Of course… the other way to look at this is to say “neutrality be damned, darker treble presentation for the win”, and then you’d want to reduce 3khz a bit and go with the Metal571 approach to EQ haha.
With that said… spending time with the LCD-5 so far has made me glance around at my possessions to see what I can sell to be able to maybe afford one haha. This thing is nuts.
