Koss are nice, but they're definitely out of my price range, lol.

  Power shouldn't be a problem at all, I saw the specs of the Emotiva, the only problem would be getting an HE-500, lol. I'm also not a big bass person so I always just skip the bass review for headphones, I only care about mids and trebles.

Sonido has gotten me wanting to try the HE-500 though, lol. But right now I can't afford them unless I trade/sell my HD 700 which I'm not sure I want to do.

I'm basically in your boat, I'm a student and I have the HD 598 and HD 700 next to me atm and comparing the two. The 700 is definitely an upgrade from the 598, I guess you could say it's a more revealing version of the 598's. I have an Audio-gd nfb 15.32 dac/amp with me and honestly I can't...

I just recently got my HD 700 for a few days and I've never heard the HE-500, but if I had a chance to listen to the HE-500 just to try it out, I might do a trade.

I'm getting the Sennheiser HD 700 and not sure which AMP + DAC combo to make it shine, anyone with good recommendations? I like trebles and mid range mostly and don't care much for bass.

Thats awesome thanks guys

I don't plan on getting a too expensive amp, maybe around 100-150$ on it and I listen to a variety of music that isn't bass heavy but usually higher vocals or neutrals. And I generally listen to aac files.

Not sure if I should get the 598 or the 600
