To continue (on paper), we see a very high S/N ratio, very good channel separation, very low THD, etc...
Not everyone likes the amp component's clean neutral and natural sound but many do. It's the same with the WA5 you called 'craptastic'. There are many fans of that amp.
If you do a search for nfb-27 on this site, you will see a couple of reviews and owners who love the damn thing.. However, if you are just talking about the amp component, then comments about the the audio-gd reference 10.32 and 10.2 apply to the nfb-27 (again, since the amp section is identical), from which you will find a number of positive reviews on the net (specifically for the amp component).
Very low THD numbers don't mean squat as those rated percentage numbers of low-level floor noise is inaudible to the ear to discern any differences unless the THD was in the hundreds range, that's a different story. What you're doing now is summarising the specs that is written by the manufacturer, maybe it's completely true, maybe it isn't do take note that sometimes those rated specs don't tell the truth and this has been seen with amp's(even DAC's) from time to time, Stereophile even 6moons have had reviews units that don't produce anywhere near the numbers manufacturers have on spec sheets, some have even failed throughout review testing.
The WA5 is only crap, maybe it was a bit too harsh of me to call it crap is because you get so very little out of the sound performance for the price you pay for, I've heard all the Woo units up to date except the electrostatic amp's. As far as I'm concerned Woo is all about build quality, rather than sound performance, big fancy enclosures that give you the impression that it is all high and mighty but only to wiped on the floor by something less expensive or extruding in looks.
Every product has fan's or followers (and some are so damn thick-headed to talk to it becomes annoying; ignorance is a bliss), there are equal amount of those that have heard it and do not like it and this doesn't apply to the NFB-27. I suggest you keep an open-mind listen to everything A2A has, then get back to me in a year.
