I found a thread asking people their top 5 at different prices or something. Many people said HD600 over and over. They rate good from Crinacle. It sounds like audiophile "purists" prefer the 600. I do a lot of EQ tuning with all of my equipment. especially car audio. So a good reference is also important to me.

Also Sweetwater has 2 or 3 years no interest.. so I pulled the trigger. I've got the Atom amp + and a Fiio dac but I'm looking at the Dx3pro+ I like the screen and people like the clicking knob.
