I've been an occasional lurker on Head-fi.org for about 5 years and have lurked at one meetup. So, I'm a bit of a noob and flirting with going further down the rabbit hole. However, I don't really see myself getting into lossless formats, at least not now. I mostly listen to streaming audio from eclectic alternative stations like KCRW as well as electronica on Spotify. Most of what I listen to is 128K. I understand that some of the stuff on Spotify is 320K, so I guess I'm getting that sometimes. I have a pair of VSonic IEMs as well as an Onkyo TX-8050 with Mission M71s, so you get the picture -- I'm interested, but haven't gone too deep.
What I'm looking for is a "better" sound experience. I'd love to get some of that warm tubey sound out of a pair of nice headphones without being too muddy or dark and a nice sound stage. My current setup isn't doing it for me and I can't have a sound room in my house or alter things too much, or spend too much, so I'm looking at getting some nice headphones. I've somewhat arbitrarily chosen a budget of $2,000 for everything. I can go open or closed cans - I can appreciate the benefits of both. If I need a DAC and an amp, please, I'd appreciate recommendations for those as well. I realize that I may be way over budget for 128K, if that is the case, I don't want to spend money that I don't need to. I'd be much happier spending $400 for everything, for example :)
Thanks for your recommendations!
