I recently started collecting vinyl and am looking to buy a turntable and some open back headphones to enjoy my records with. Right now I am using some modded JVC HA-RX900s being amped from my PC's sound card which sound pretty good to my ears but I want something more balanced and, well, open. I mostly listen to heavy metal, electronic, jazz, and folk.
My plan so far is to get this turntable (u-turn Orbit):
Run it directly to this amp (Objective 2 with RCA input) and then...I was looking to spend $200 to $500 on a good pair of headphones. I was eyeing some Sennheiser HD 650s and Grado SR325is but then I saw the previews for the Hifiman HE-400i supposedly coming soon. Any suggestions on what would best suite my needs?
