R2R 11 or NFB-11 for AKG K712?
Just got the headphones yesterday and was running them off a FX-Audio X6 ($80) as a DAC and JDS O2 as an amp. It sounds pretty good to me but I am wondering how much more will they scale with the R2R 11 and also if the warmth of the R2R will take away some detail (some say no and that it adds even more!).
I've heard people say K712's go well with tube amps (which are much warmer than the R2R), so a warm SS would be good and not too warm? In any case both the R2R and NFB 11.28 are both said to tame the highs a little and also add more sounds stage and better dynamics. Will I be better off upgrading to say, an ODAC, to better my $80 DAC and keep the O2 (might be too bright on some songs and struggles to push the K712's in some low volume songs when in full power/ low gain) or go for the R2R 11?
I feel I'm not getting the most out of the phones, even though it already sounds really good.
Recommendations? Any experience with Audio gd and AKG's? or more specifically K712's?
PS. I don't care about the popping (is not even bad), the FX-Audio I have now goes pink noise when I change from 16bit to 24bit and have to unplug the USB and reconnect it. Most annoying thing ever, hurts my ears
