I've only found a few IEM's a step above the GR07's in the 400$ price range. Sony MDR EX1000, Westone 4 , PFE 232. These IEM's I just named all of course has fantastic bass and just overall beautiful imaging. I would throw in the Heir Audio 4.ai if you don't care a lot about bass. The 4.ai provides great punch and it's very fast and I personally think the 4.ai has perfect bass response depending on the recording. If the Recording of the song has lots of bass the 4.ai will have lot's of bass. If the recording has small amounts of bass then the 4.ai will have small amounts of bass. When I first got the 4.ai I wasn't all that impressed with it and I've came to find it was due to a fit issue. Well all that changed once I added my Sony Hybrids on to them and I must say I am very impressed with them. The Imaging and clarity of the 4.ai is marvelous and it's definitely a worthy upgrade. But I still must say the GR07 aint no slouch. It definitely gets the job done and is still and will always be my favorite IEM. GR07 fan fo life, you just can't beat that $179.99 Value Price tag.
