Sound Characteristics: 
"Neutral but smoothness sounding ,it doesn't sound skeletal or digital (or metallic). There's meat aplenty on them bones . It's a sigma-delta DAC chip implementation without the dryness, neutrality without the emotional disconnection" - John Darko

Feedback :
John Darko review the NFB-2.1



1, What's different between NFB-2.32 and NFB-3.2?
The main differences are as follow:
        1, The NFB-3.2 applies 2 groups of
class A parallel connection PSU supplied for analog output stage, (the analog output stage power supply is very important, so we keep the 2 groups of class A parallel connection PSU here). Another 5 groups of linear PSU's supplied for other parts.
            The NFB-2.32 applies 6 groups class A parallel connection PSU for the whole gear, and 1 linear PSU for the control parts.
         2, The NFB-3.2 applies
a toroidal transformer, the NFB-2.32 applies an R-core transformer.
         3, The NFB-3.2 applies mostly 1% SMD resistors and caps, the NFB-2.32 applies mostly DALE resistors and WIMA caps.
        4,  The NFB-2.32 sound better than the NFB-3.2 on detail , high / low extend but the different not as the price different.

4nd June , An user from UK:

          Just a note to say thank you for the DAC .. it is a noticeable improvement over my Maverick D2 and is able to distinguish musical behaviour in an excellent way ..

          My friend has an Aqua Audio, another friend a Wadia and I also have a Crystal DAC .. yours is better .. so thank you ..
