What do you mean by "bringing the flash"? Are you talking about micro SD cards? They are quite small but very portable and having 32 GB cards on the cheap now ($30.00) is a much more efficient way of having lots of music on the go. Soon the 64GB cards will be reasonably priced and at that point will completely solve my upgraditis.
The only way I could explain the IE80 with the Studio V to you is imagine your IE80s with even more clarity/transparency, more detail, very wide sound stage. Where the coloration is coming from the IE80 and not the DAP so letting you hear what the IE80 is really capable of. Left and right channel balance crazy good.
