GR07 is much better than GR10, only thing GR10 does better is lower mid detail and imaging. GR07 has solid treble extension with the right tips, certainly way better extension than the GR10
W4 is certainly better than the GR07 though, you just need the right tips and set-up. In stock form the W4 is merely slightly better, but can be taken to another level.
Whatever, I didn't say it was better even though I personally prefer it. I said it had better low level detail and that I could find faults in all. Take another chill pill and put down the pointy stick. I wasn't ranking to avoid zealots and just stating why it's not a top tier. Some things considered top tiers aren't either. No biggy. Even Eke agreed with the specifics.
