I was listening to my GR07 MK2 again today....
I'm in two minds whether to sell them atm.
My problem is the timbre......it's so very natural,l I don't know of any IEM that can replicate percussion, strings, vocals anymore realistic than what they are with GR07. It's clear listening to Taylor Swift I cannot replicate the natural tone and edge with my H-100 Hyrbid. Switching between the two beside their different warmth and brightness levels the body / weight to instruments has great balance over the spectrum with GR07.
Though there's a trade off or two for that timbre. Layering, there's less air between instruments they feel slightly congested or smothered with other samples. I find it awkward sifting through the separation deeply picking out one instrument or sample, the dynamics are not up to speed feeling dull, boring as some put it. And last of all soundtage depth isn't well displayed. These are things H-100 does overly well without the timbre or tone of GR07..
So really what I have is one IEM that excels in excellent timbre and tone, another which excels in sound-stage and imaging. Both trade off the others advantage. I guess it comes down to which sections I mentioned one prefers the most.
It's hard to say which is better because while I find personally H-100 is technically advanced, I prefer good separation and dynamics, timbre takes up a large percentage of the listening experience. I wouldn't recommend owning both at one time, because they truly cause headache switching between them.
But I must add, this is only a quick summary and by no means the end to all things between them, there's many areas I have not covered such as the over all signature and crispness something like H-100 displays it's advantage of being a (Hyrbid) BA and dynamic in one. I am finding GR07 too warm for my tastes now overall. But the timbre surely has some advantage..
