Okay so I will be getting my money this thurday but instead of getting the HD 650's I think I'm gonna go with the Denon D2000.
What do you guys think about using the fiio e11 with the Denon D2000, and since they are low ohms, should I use low gain on my amp.
I actually just basically traded my HD650 for the D2000. I was amping the Senns with a NuForce Icon-2, and I thought that it was fine, no big. Good soundstage, good-sounding. Not a bad headphone, but I sort of suspected I didn't have a good enough amp for them, since they sounded exactly the same being driven by my MacBook Air and iPhone. Now that I have the Denons, I can really tell (ironically?) that the HD650s must be really good. The D2000 sound incredible, basically, which makes me think I wasn't getting nearly enough out of the HD650. If you don't have a good enough amp for the HD650, I wouldn't recommend them. I bought them figuring I'd upgrade my amp, but I never did. I'm really glad I got the D2000 now, but I bet the HD650 sound awesome with a good amp.
