I am looking for an upgrade system for my HD600. My budget is $1000.
 
I used a Tubedac 11 and now I want a better one.

Schiit Audio makes a whole assortment of affordable and very high quality bits of equipment. LittleDot makes good tube amps I hear, and I haven't actually seen a whole lot of other DACs and amps that pique my interest, either due to price or features.

Audio-GD, Little Dot, or Schiit are all good choices. Look no further

I love my Schiit Bifrost DAC and Bayerdymanic A20 amp.

All of the above can probably make you happy. Let me add something transparant like the Yulong D200 plus Bottlehead Crack. Your HD600 will thank you
