Swspiers you listen to bot orthos at Fiio E10? I couldnt agree about subwoofer bass at 5LE, maybe some added body on higher bass-lower mids but in overall SQ its quiate subtle and nice matched.
Generally if I were you I would give both cans serious time before making final decision. Im also waiting for more impression from battlefield:)
It never occurred to me to use the E10 for these cans. Not enough juice, especially the 5LE.
Please don't take my observation of the sub-bass performance as a criticism, just an observation. The 5LE's have given me some of the best moments I've ever had while listening to music. However, the power and heft of the low-bass regions do obscure the mids a bit. There's just no way to avoid that without shooting for a flat response, which the AD's do very, very well.
