Asked a similar question in the PC audio section, but I don't think I'll get too much out of there in regards to a variety of opinions (Although what I did get was good!)
I currently own HD595s. Very good headphones, I love the sound they give out. However, I want to upgrade to an 'actual' audiophile experience. (Something to justify all those FLACs I have)
I'm pretty much decided on the HD650s. I noticed I can buy those in a bundle with the Graham Slee Solo II SRG for cheaper than buying both on their own. I've heard before that Senn used to demo the HD650s using this amp, but I'm not sure of how it's rated on here. It would be easier for me to get a hold of, being UK based myself. Thoughts?
As for the DAC, I'll admit I'm pretty completely clueless in this regard. I can use a cheap soundcard and pass it to the DAC when I want to game, so I figured I can just get a good USB DAC and that'll be that. I've seen the Stello DA100 mentioned, but other than that, I'm clueless when it comes to them. Where is the point of diminishing returns, etc?
My budget is decent, so you can hit me with what you recommend the most and then scale down in price if you want. Perhaps after that I'll be able to decide on a good budget. (Basically right now, at the point of diminishing returns)
Sorry if I sound clueless, hopefully you guys can knock some sense into me.
