Was comparing these two the other day, The MA750 is great, and has a nice full sound, but I think the IM70 has better transparency and a bass that's not "blurry bloated" as in the MA750 (just a tad). I agree that the IM70s are more forward. Probably better cable and and shell construction with the RHA, but the sound is better to me with the AT. Either one is a good earphone to have in that price range. Oh, the RHA has the more warmer sound.
Thanks. Looks like the IM70 just edges it then. I'm guessing both are better (especially bass quantity and quality) than the CKN70?
