They are raved about cause of the THD ratings. But i dont really care about that. How silent do i need it to be? am i willing to sacrifice other important amp features for more silence of things i usually cant hear anyway? lol.
Mon said what it was he didnt like about it. as a matter of fact theres a whole thread on it here:
I thought my THX amp was the shiznitz. but when i upgraded to the RNHP i was like WOW 
sounded so much better. more colorful, more full, it was like i got another better pair of headphones. I havent heard many amps but i would like to hear others that compare to the RNHP to see how they compare. Also looking to upgrade but i dont know what to. Tell you what though. its not gonna be a THX amp
