I finally tried out an open ear set with the HD518s to upgrade my home listening from a pair of HD202s. I love absolutely everything about these cans from the fit, design, weight, cord...all except for the sound. I felt the difference between closed and open ear almost instantly and was at first distracted by this. But what quickly became apparent in my favorite recordings was the lack of overall detail, especially in the mids. Now why would I be preferring the sound on my vastly inferior HD202 closed cans...to my ears it feels like sections have simply been scooped out, leaving portions muted to almost inaudible while refining the low end and giving more high end range.
Is this merely an issue of needing a headphone amp, or is this the way the 518's are meant to sound? I've only been listening a few hours at a time due to a new job with long hours, but it doesn't seem like a burn in thing unless they take a massively long time.
I listen to all lossless sources, hi-res occasionally and my own vinyl. I've tried my usual setups, which consist of: Headphone into desktop PC audio card (basic onboard card with Realtek..nothing fancy, but straight audio played via foobar), Headphone into Yamaha stereo receiver for vinyl, Sony multichannel receiver for movies/games and into Rockboxed Sansa Clip+.
Any help would be appreciated, as I'll be the first to admit that I'm a complete newbie when it comes to dedicated headphones.
