Headphoneus Supremus
Have you tried the HD660S with a tube amp? The choice of amp is what makes the HD650 the slightly better headphone to me over the HD660S but if I didn't want to deal with amps or only have SS amps then the HD660S is the clear winner over the HD650 and HD600.
I've only had the 660s for less than 24hrs so not yet....but I usually like to keeps things fairly uncomplicated...my main rig is a CD player straight to a SS head-amp...no computers, no EQing, no fussing with tubes or whatnots...
But even still ...since having the 580s, 600 and 650s (x3) in and out off my system for almost 2 decades the 660S appear to offer IMHO an upgrade as far as "my preferences" are concerned.
Then again it's a new toy...so as we are all so painfully aware of once you spend a bit of time in this hobby...things change....in the meantime Underworld is sounding really good...better than I recall on the 600/650s.
