Get the Onkyo ES-FC 300. Its available for Rs6200 from Snapdeal. Its excellent. I do own a JVC HA-MR77X too but would prefer the onkyo as an all rounder over the JVCs that prefer electronic music over everything else.
I got one. Its genuine.It is sold by Onkyo India. I even have the bill delivered directly and separately from Onkyo India by FedEx.The Mrp is 9995. All other sites are selling at old mrp or importing them which won't cover the Onkyo India warranty. Buy it as soon as possible.Its a big step forward from JVCs non existent Midrange and Highs. Its very insightful with far more deep and accurate bass over the JVCs even at low volumes and even when driven without an amp.
Soundcard won't amplify your headphones. All those built in headphones are a hogwash unless you buy a real dedicated amp. Sound cards are DACS primarily and foremost and then everything else. Get a Fiio E11 K2 and then you'll know that you haven't yet heard music like the way you should have!
