I'm a bit new to the "audiophile," but I've been trying to broaden my horizons as of recently. Right now I have ATH-M50s and I do enjoy the sound quality compare to what I've used to own (which were headphones around $30 or less). However, I know that this is sort of low-mid quality compare to others. Right now I have two options and I'm primarily trying to get the best type of sound quality for overlapping genres (I listen to basically every genre). I hear that getting a DAC/Amp helps improve on it(or at least improves on something like it.). Or, to buy another pair of cans altogether. Preferably one that does not need a amp.
I listen through the PC (via a Ear Force DSS via optical cable), Iphone 5s, and Ipad 2nd Gen. I only really need this to listen to primary for music. Movies aren't an issue and Gaming I have cans for them. Only want to pay 200 for the AMP/DAC and up to 400 for the cans.
