sorry if I didn't get it by now and I should have, but do you own also the 650s ?
what's the eta on your nfb11 ?
yeah i have quite a few dac/amps and headphones - but most of them collect dust, my sennheiser hd650 and o2odac are what i use the most along with jbl studio monitors. i did not order the nfb-11 yet, i may have to wait til next month because i bought a ton of stuff this month as it is, but hoping to get it ASAP.
