Best Dac under $600... New or used

I'd look at the new Parasound Zdac v.2. I have the original model and think that it's ridiculously good for the money. It's very, very close in performance to my Benchmark DAC1 but with a touch of welcome warmth that the Benchmark lacks. The new Zdac has a volume control so it can drive a amplifier directly.

Second Truman above, or Mapman. Can't go wrong.

You could also go for a Micro iDSD from iFi.

I second the Bifrost - with the UBER upgrade - have one - love it!!!

I found a benchmark dac 1 local for $425 but I think its going to be too bright for my tastes...

I purchased some older Monitor Audio 2.5 Golds yesterday and I think they might already be on the bright side. They're beautiful and in mint condition so I figured if I didn't like them I can flip them.

I'm looking into that constatine! Thx for that suggestion. It looks promising.

I'll also look into the bifrost some more. It looks like a quality piece.

My last dac was a z dac and I thought it was really nice. I liked it quite a bit. I'd like to try something different but I may end up buying another one anyways, just because I did like it. You can pick up the first version for $299 now...

Anyways, thanks for the replies! If anyone can think of some more let me know! I research any and all recommendations!
