In Reply to: RE: Playing with NCore NC400 Class D posted by mitch2 on October 14, 2014 at 21:25:25:
boast specs that are way over-optimistic for sensitivity and impedance curve. A speaker advertised as "87 dB and 4 Ohms" more often than not actually measures more like 84 dB dipping into 2 Ohms easily in large portions of the frequency response. In these cases, more power will make a difference.
I did try the NC400 monoblocks on my custom speakers which truly measure at 95 dB sensitivity at mostly 7 Ohms, and they sounded extremely similar to my tricked-out 2A3 SET monoblocks which make 3 watts/channel. NC400 sounded very pure, natural, without overtly spotlit detailing, which means those expecting some kind of fireworks or strong impressions will likely find them too neutral. Of note, these class D amps seem especially sensitive to power cords and power conditioning, so people's experiences will inevitably vary..
