Hello,
I need help figuring out which of the following will deliver the most concert and roomy feeling in custom IEMs while playing classical, rock, jazz, and pop music genres. I own the Sennheiser HD800 and I need to know which of the following will near replicate its sound.
All Universal IEMs will not be considered including Sennheiser IE800 or the AKG K3003I

Supposedly UERM is closest, at least that's what the guys I know who own both tell me.
