So I know very little about high end headphone set ups but have $1500 dollars to play with. My best headphones that I've had are the Sennheiser HD449's powered from a Ipod Classic. I'm mainly looking to buy a headphone for both portable and home use here though as well as an amp and dac. I have a pair of KEF X300A active speakers (which are near field) for usages at home most of the time and I'm looking to get a closed pair of headphones for when I cannot use the speakers. I connect the Speakers to my computer as it has a USB dac inbuilt. I prefer Dac/Amp units to be a combo unit.
I almost mainly listen to both Electronic music (DnB, Dubstep, Ambient, Psy-Trance, IDM, Glitch, Trip Hop, Trap, Chillout) and to artists like Pink Floyd, Sigur Ros, Tool, Rage Against the Machine, Animals as Leaders, Liquid Tension Experiment, Porcupine Tree and others. I love Korean pop music and some select Western pop ~ almost exclusively female singers. I also listen to game and movie scores that are classical.
My listening would be 50% electronic 20% Pop/Kpop, 20% Rock/Metal/etc - 10% soundtracks. I do not like most heavy metal bands at all other progressive or instrumental acts, I almost never listen to Jazz and I don't like too many old school rock bands.
I prefer my bass to be fairly strong but never boomy or anything and I would prefer more treble than the hd449 as it can lack a bit of bite at times and sounds a bit muffled for classical compared to the KEF. Coming from speakers I want the soundstage to be of a fair size.
I live in Newcastle Australia. There are no local stores that I'm aware of that stock high end equipment.
Thanks for reading.
