My NFB-11.32 arrived today. I ordered it with both TXCO clock upgrades. I've kept tabs on A-GDfor quite some time.. but sort of avoided them b/c of their tendency to release a new amp/DAC/combo (seemingly) every month. I'm slimming my upstream gear down so I needed a DAC/amp combo unit (while I await the Geek Pulse X/LPS which arrived in June). This seemed like a a great opportunity to try the (relatively) affordable NFB-11.32.. for the LCD-2 as well as my custom IEMs. Correspondence with A-GD/Kingwa was prompt and enthusiastic... and shipping was ridiculously fast (unit shipped from China on Saturday.. and arrived today/Monday.. wow!).
Unboxing the 11.32, I was pleasantly surprised by the build quality. It's not "Violectric" grade .. but the smooth, brushed aluminum case.. reliable toggle mechanisms on the switches, and solid connectors reassured me that there was some attention to detail (given the price point) given to the external quality of this unit. I'm running Windows 8.1/x64 and after following the directions, the driver install went flawlessly. I've also experienced no pops/clicks/dropouts of any sort.. even when switching between players & file types (i.e. a Soundcloud stream from a browser session.. to FooBar playing Hi-Res audio.. to videos in VLC). I'm relieved to have such stable performance (so far) since I remember reading about many A-GD owners (of past A-GD DACs) having frustrating issues with drivers and audio performance.
I'll comment more on the sound after I give the unit significantly more use.. but ootb, it sounded a bit thin, bright, and compressed w/ the LCD-2. Leaving the unit on for a few hours while playing music through it, the 11.32 became noticeably more dynamic, weighty, and clear. I haven't used the unit as a standalone DAC yet, so I can't comment the quality of the DAC implementation, but as a DAC/amp combo, it's quite impressive so far. Transparent, dynamic, "naturally" resolving, tonally accurate.. possessing a very black background & a well extended frequency presence.. are the qualities that immediately come to mind. The volume pot is smooth and seems to be of high quality as it relates to the impact it may have on the sound. The treble rendering was one area that was immediately distinguishable.. it's got excellent depth, extension, and resolving ability.. yet lacks harshness or a 'clinical' quality with even less than "well" recorded material.. it doesn't seem to possess any glare, either. I'm not sure if this is the work of the DAC section.. the amp section.. or a combination of both (probably the latter).. but this type of performance is impressive and welcome, nonetheless. The mids are, again, smooth & detailed and mostly accurate.. they do seem to possess an ethereal sense of warmth and liquidity that gives them a slightly 'glossy' quality. The bass is wonderfully extended.. accurate in reproduction.. and can be very punchy if the music calls for it. Sub bass extension is terrific and effortless. Soundstage feels accurately proportioned to what a recording serves up.. it doesn't exaggerate depth, width, imaging, etc. So far, the NFB-11.32 is notable (and impressive to me) because it gets little to nothing outwardly wrong more than it gets a bunch of things "amazingly, jaw-droppingly" right. At the price point, you could certainly do a lot worse.
My experience with most desktop amps/DACs I've owned or used for an extensive period of time.. especially ones that employ a discrete design.. is that they tend to fully 'open up' after a hefty number of hours of use (the Violectric V800/V200 stack needed a good 200 hours before the sound "stabilized"/didn't change).. so I'll revisit the SQ after I get more use with it.
