Wondering if the 50$ difference is worth it. Have a HiMan 4xx and a MASSDROP X FOSTEX TR-X00 headphones plus a handful of IEM's. Source is a turntable(pro-ject debut carbon evo) with a phono preamp, a SACD player, Hidizs AP80/DH80s combo. Currently running through a 25 year old Sony receiver which isn't too clean sounding with the higher quality sources.
