What's improved in the
NFB-7.32 from the NFB-7?
1, USB-32 built in, ultra low jitter
re-clock ability can cooperate well
with ES9018 without sound drop off .
2, All digital and analog signal circuits power supply by 15 groups
class A parallel connection for the best sound reproduce.
3, The analog output stages built on the main board without modules
4,There is no compromise building , have not any parts can for
upgrade , built in all audio grade parts , OCC wires, TCXO , ect .
Fully balanced design built by discrete analog stages without any
OPA and couple caps in the signal channels.
Non- feedback ACSS analog output stage .
Uses 3 units R-core transformer , more than 40,000uf audio grade NOVER capacitors are used to ensure
ample and smooth power feed.
A total of 15 groups of high-quality class A parallel connection PSU
connect to double-stage PSU power supply for all digital and
To achieve high S/N, the control circuit is powered with
Uses most Hi-end grade parts and exact match transistors.
6 groups digital input :
coaxial BNC / AES / coaxial RCA / Optical / USB / I2S
DAC output :
XLR / RCA / ACSS
USB Audio Class 2 High-speed Input from Windows / MAC / Linux
( We can not guarantee it can working with every Linux device )
The USB supports High / full speed Asynchronous Transfer Mode up to 384K / 32Bit
Resolutions support 16 / 24 / 32 Bit with sampling rate support
44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz
The first version NFB-7 released at Oct. 2010 , It have not USB
version but still
had got a lot users favorite . That time we have not the high-end
USB chip available for cooperate with NFB-7 .
Since the NFB-7 first version release, we have search the 192K
USB chips cooperate with the ES9018 for the best performance
On the web browse , I read some the ES9018 product users
feedback experience sound drop off with some PC sound card .
Discuss with their engineer , he explain the ES9018 built in
an extreme high performance 1 GHz PLL ( ADI , the one of best
PLL manufacturer in world ) avoid jitter , as most
technicians know , ultra high frequency PLL have high request
from input signal , not to refer there is a 1GHz PLL built in ES9018
They are put the aim on Hi-End audio area not low-fi, so they
won't increase the compatibility cause the performance degrade .
We design the high speed TTL process circuit for the ES9018 coaxial input
For the best signal level match, better sound and lower
request from sources than manufacturer recommend design .
In our experiences on sell the Sabre products , only have around 1%
users feedback have the occasional drop off or can't support high sampling
signal input with connect to some PC sound card coaxial or optical
This is not the fault in the ES9018 . It is the source have
higher jitter or worst SPDIF level not arrive ES9018 request .
This just like the low price car can run by low quality gas but the high
performance sport car can't .

( Released at Sep.
After do a lot practices with
almost well know chips , only two USB chips can work fine with
ES9018 through I2S connect direct , The USB-32 chip is the best combo with E9018 we are
consider, but its high cost ever block us back several
It is much cost than any USB chips as we had know .
USB-32 chip is worth the price, it had 32bit / 384K Asynchronous Transfer
ability and the Hi-End grade sound quality .
In NFB-7.32, even though the ES9018 support up to 32Bit
/192KHz, but the USB-32 chip have 384KHz support ability which is mean
it have strong data process ability and very low jitter PLL , can
reproduce the better sound .
The NFB-7.32 USB input is so superb so it without drop off unless your computer very busy to
process other softwares and stop response .
USB-32 chip was released July, 2010 from the large audio
and IT manufacturer , through two years grow up, it
already very mature and steady .
All USB chips have the ADC and SPDIF RX , we asked the manufacturer custom design the drivers ,
remove the ADC and SPDIF RX , put the
process ability on reduce jitter and improve on sound quality , so it
have extreme low jitter and very detail sound without harsh .
USB-32 chip have quite low request from the computers. We test by a
SONY web book , 1G memory with an Atom Z510 CPU (WIN7 home
version), the web book even can't play 720P video but can work fine with
NFB7.32 .I advice users
setting on 32 bit output in the computer
, even playback 16bit files , 32 bit transmit keep the ES9018
working at the best state for the best sound reproduce .
