    Best Amp for a Sennheiser HD700?

    I saw mentions that the HD700 pairs best with a Tube Amp. Right now I just have a FiiO E17 Portable Amp and a Creative Titanium HD (which I don't think even has an amp built in).   My budget is around $200-$400.   Should I be looking at a Solid State Amp or Tube Amp? I guess I should also...

    6AS7G/6080, 6DJ8/6922 Tube Sell-Off! (Woo WA3, Bottlehead Crack, Aune T1)

    I recently acquired my first tube amp (WA3), which has in turned exposed me to the perils of tube rolling.
