a little light on the bass, but perhaps true to the recording, nothing ever sounds boosted, nothing ever sounds anemic, its just how the recording is. the bass comes out when u least expect it. extension is the best i've heard. u hear all the bass details, textures, nuances, with every headphone.
the midrange is just slightly laidback, but not recessed, i would say, relaxed, mellowed, but it doesn't lose any speed, dynamics, clarity, or forwardness.
the decay is perfect, very natural, not SS and digital, but not colored either, and music just is so transparent, the music is very ethereal sounding at times, the way it just plays through, its really interesting. theres no grain, no hardness, anywhere to be found, the background is certainly very black, this is a dynamic amp, but it doesn't sound dynamic, it doesn't sound forced or aggressive in any way, its the perfect balance of being relaxed and dynamic at the same time, it finds that magic middle.
the treble is just enough to extract all the details. but not be fatiguing, with HD 800, it seems to sometimes border on that level, like u feel like its bright and its gonna fatigue, but in the end it doesn't, its quite like the hd 800s sound. other headphones don't seem to be bright. not warm either, theres no roll off, my DAC seems to have a little brightness at times, but its not artificial or digital, just very revealing and doesn't hold anything back in the treble, if your recording has treble it will be there, but it will only be what the recording has, it won't be unnatural sounding or adding any brightness to fake detail.
the details really are there and its the amps incredible resolution, not treble colorations like some SS amps give.
this is what i hear, and comes close to what people say the Mytek 192 sounds like as well.
