Hey head-fi! I am an amateur audiophile (although I probably rank more as a music listener than a critic). My first pair of headphones I've ever bought is my Audio-technica ath-a900 (the big blue ones). I love them, but would like to upgrade. I am looking for a pair of fun, detailed over-ear headphones that are a bit more portable than my big blues (the wings seem to increase the size tenfold). Something with great all around sound, with no skimping on the bass (but nothing too strong). My budget is max 400$ (so higher end headphones if below 400 used). Also, would I benefit from using a desktop DAC and amplifier? I don't want to pay much more than 150$ for the DAC.
I listen to pretty much all genres, so nothing with too much emphasis on any frequency range.
