How to install the
TE8802 driver?
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 (
another 1
linear PSU for the control parts ).
R-core transformers.
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.
3 channels digital input :
RCA coaxial / Optical / USB
DAC output :
RCA / ACSS
USB Audio Class 2 High-speed Input from PC/MAC
Supports full speed Asynchronous Transfer Mode
Resolutions support 16 / 24-Bit with sampling rate support 44.1kHz,
48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz (USB model)
Supports up to 24Bit/192KHz (Coaxial )
Supports 2X , 4X and 8X oversampling customers setting
Memorizes all settings and it could resume the last settings when
power on.
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

1,
What's different between NFB-2.2 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-2.2 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-2.2 applies an R-core transformer.
3, The NFB-3.2 applies mostly 1% SMD resistors and caps, the NFB-2.2 applies mostly
DALE resistors and WIMA
caps.
4, The NFB-2.2 sound better
than the NFB-3.2 on detail , high / low extend but the different not
as the price different.
