Any insight as to how the Sony MH1C and the Nuforce NE-700X compare to the Vsonic GR99? I have the Vsonic, and the descriptions of the Sony and Nuforce sound similar to the Vsonic. Would either be an upgrade over the Vsonic? In particular, I'd be looking for something with a similar overall sound signature to the Vsonic but a bit better performance in the midrange (a bit more clear and a bit less veiled in the mids).
Thanks in advance for any insight.
