I'm looking for the same thing--though, something that will specifically fill out the lows with my GR07s.  PA2V2 or CMOY?  What say you?

Yes, Kyle, they have completely different sonic signatures.  I would appreciate if you would share your experiences and thoughts, rather than your text formatting skills.

I'm looking to buy IEMs in the $200 range. I've heard good things about these 3 products, but I understand they're very different. A lot of people seem to like the GR07... I've heard the IE7 is good with bass, and that the HF5 are very accurate (though some say lacking in bass response). Thoughts?

Hi,   I'm looking for a pair of IEMs in the $200 range.  Any suggestions?   I want something with good sound-isolation, and reference accuracy.  My main pair of headphones are are AKG K240s, and I love them to death.  Is there anything with a similar signature?   Thanks.
