Been reading on these cans & amp. Which would you recommend ? 1) DT880 with PA2V2 2) D2000 with PA2V2 3) DT880 with Nuforce Icon Mobile 4) D2000 with Nuforce Icon Mobile Feedback is much welcomed. Thanks

Hi all, Hope someone can help to answer some questions here : Based on the amp performance, are all these 3 the same ? (forget about Cute II Battery uses rechargeable & Fubar has DAC). I read somehwere that Cute Beyond is class A amp, while Cute II Battery is class AB amp. How much...
