yes in detail its more or equal the same as the DT880 600ohm with unamped condition while the DT880 is amped.. but the DT770 pro 250ohm has one major problem and it is it's flat response.. it will sound very very lifeless and very very unforgiving to sources, some ppl find it sounding as if alot of things being thrown at you as well ... its for professional usage after all and not for casual/relaxing listening

dt880/600 is tuned to sound linear and also having the capability to produce the details very close to DT770 pro.. its actually a really good buy and worth to save up for if youre willing to.

not sure how the NAD302 will sound with the beyer.. but after testing a few beyers, i find that they're all very sensitive to amps and i suggested the orange amp cuz i find them as one of the best

i wont recon the 32ohm cuz if im not mistaken its about the same price as the 600ohm

NS good what.. free from spending for 3 months and you get RM300 also ... take it slow man, the headphones and amps wont run away

Oo.. lotsa info bout beyers. thx a lot
I got lotsa 32 ohm headphones d... wanna try out some serious 600ohm

btw...NS is nice...i know that
but can get RM300? owh? free moneh???  

Oo.. sweet
at least going to NS is worth a few hundred bucks
