I am not even sure what this question means-- it is the top of the Mrspeakers line, does it compete with the world's best headphones - I think it is in the same league as other "best" cans.
I have been using the Primes with my Icon HP8 Mk2 tube amp, and various dacs (currently a NAD M51) as well as with the micro iDSD. I am still in the burn-in phase, which lasts for some time for me...... I run the micro 24/7 from my vortexbox computer, but I do turn off the Icon to not kill the tubes too quickly. That said, the big rig is better, but the micro holds its own surprisingly well. It works well with many headphones and iems, from the more neutral/detailed like Kaedes and HD800s, to more warm, rich poweful bass types like the Primes, Noble N6s, and JVC DX1000.
I liked what the micro does well enough to by the Primes based on that pairing at RMAF, and nothing I've heard at home would change my mind about that. I am loving the Primes with either of the two lash-ups. You'll have to pry my micro from my cold dead fingers!
P.S. please don't try that - I'm a nice guy!
