Anyone interested in nearly perfection on a headphone a a great price??

What are some of the headphones that you feel these have bested and what are you using to power them? Enjoy the music

To begging the HP-2 Are better than all of the cans I have right now. Those include my Original TH900, HD600, HE-560, Hyland saturns, I have owned HD800s moded and non moded, LCD2 and many others. I have also listened to almost every headphone brand and most of their flagships, Talking about bettering, I at least by memory can not remember a headphone that goes as deep while still providing controlled and most detailed lows, including the LCD4, Final 8000 pros , stax flagships, Sony’s closed flagship and many others.
I use mainly an Apex peak/volcano with many 6sn7 tubes, feed by a innuos Zen MK3 and a direct stream dac powered by Shunyata Triton/typhoon . I also have a Luxman DA-250 connected to my iMac and a little dot 6 that I use for the hi fi man HE560 which require tones of power.

Thanks for the input,  will have to get my ears between a pair of these as I am looking to add a closed back set to the three sets of planars that I have retained while buying and selling in the last three years. Do you feel that you are giving up anything because they are closed back or feel that might be some of their appeal?  

@cheche9, thanks for the heads-up. There's also some good info about these cans over on Underwood HiFi's site. Looks like a great value for under $1,000! All the best.
