What cans should I buy?
What I have now
PC + Audio-gd Compass + DT770 Pro (80)
What I will use them for
PC Gaming
Indie Pop/Rock, Electro, Classic Rock, Blues, Hip hop, Jazz, Classical (I listen to almost everything. I listed genres in rough order of relative time spent listening.)
I like bass, but if I had to choose I would pick tighter bass over powerful bass.
What I'm considering
Sennheiser HD650
HiFiMAN HE-500
????
I've been considering upgrading to HD650s for the last year or so, amidst frustration that the price on them has shot up around $100 over this time. Considering this, the fact that I have a better job now, and that I haven't actually put in any real research time into cans in two or three years, I decided to open up and look around more for something better. So, I have now discovered the HE-500s, which while $300 more than what I had originally intended to spend (200 now), have me extremely intrigued and tempted to just go balls to the wall. My spidey sense tells me there is some degree of FOTM effect going on with the HE-500s, but they seem to offer a lot for that extra $200 spent. Meanwhile, at $500 for 650s I'm left wondering if I'm better off spending less for something like MDR-1Rs or countless other awesome headphones in the $300-400 range. Finally, If this Compass DAC/Amp isn't the ideal setup for the upgrades I'm looking to move toward, I am open to upgrading that equipment in the near future, maybe a year out.
So given all my variables, what is my best choice for cans?
