Just wanted to give my appreciation to ClieOs and this review, without which I would never have gotten the GR07. Also love the creative title, Labor of Love! Simply amazing IEM that made me switch from the DBA02/B2 sound signature completely(won't even listen to it any more). One thing I wanted to mention is the incredible synergy with the Studio V. With the dynamic firmware, the GR07 takes a step up in cleaner, more transparent sound than even my 601/uha4(standard opamp). I would describe the increase in clarity between the Studio V and 601/uha4 as between 30 to 50% depending on your ears and/or what's between them.LOL!
Listening to acoustic, vocals and even classic rock there is definate increased clarity/transparency across the spectrum. I recently got the JH5 as a recommended "stepup" from the GR07/DBA/B2 fellows, yet incorrect fit has kept me from making any comparisons. In terms of tips I use the small oval stock tips, not a deep insertion kind of guy..in terms of tips. Did try all 3 sizes of the Jays, but their tips are slightly different diameter so I couldn't get a comfortable fit. I also want to mention that I've come across some suggested GR07 upgrades, from the sonys 7750, ex1000, re272 and jphonic k2 sp. If I'm not happy with the JH5 I'll definately explore those.
