Fully discrete analog stages without any OPA and couple caps in
the signal channels.
Non- feedback ACSS analog output stage .
6 groups non-feedback Class A power supplys for the whole gear (
linear PSU for the control parts ).
More than 20,000uf audio grade NOVER capacitors are used to ensure
ample and smooth power feed.
Uses most resistors are 1% DALE , most caps are the WIMA caps .All
transistors are Toshiba and Hitachi.

"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
John Darko review the NFB-2.1
What's different between NFB-2.32 and NFB-3.2?
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
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
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.
