Today I received Pure Netrwork Audio nBrdige +.This is a Hifi network streaming player with many technologies.
I read the manufacturer's introduction and was shocked by many advanced technologies. I never thought that there could be so many advanced technologies for network streaming players.
The following description is translated from the manufacturer's website:
Fully isolated modular hardware design
In the hardware design of Pure Netrwork Audio, one of the biggest concerns is how to reduce interference to avoid degradation of its own clock (digital transmission) or back-end DAC clock (USB transmission).
In terms of isolation, Pure Netrwork Audio uses optoelectronic modules to isolate network interference; uses battery power to isolate mains interference from other parts of the network; uses a chassis split design to isolate the clock transmission lines inside the machine, thereby avoiding internal EMI And so on. It can be said that the music bridge uses a fully isolated design to ensure sound quality.
At the same time, the music bridge adopts a fully modular design, which provides a convenient upgrade path. For example, to upgrade from nBrdige to nBridge +, the user only needs to send back nBrdige, add a digital interface board (green board in the picture, the actual sale is black) and replace the rear panel. In the future, other hardware upgrades only need to replace some components, which greatly reduces the life cycle cost.
High-performance customizable software design
In actual use, the higher the real-time data transmission performance, the lower the CPU usage, and the better the sound. So Pure Netrwork Audio's software focuses on high-performance design.
On the one hand, according to our design experience in high-performance network equipment, a large number of rewrites of the Linux kernel have been made to greatly improve the efficiency of the system, improve the real-time performance of the system, and reduce the CPU usage.
On the other hand, the software uses a module independent control design, which can be used to shut down system functions that are not needed in the music playback process, such as management services. For example, ROON users can turn off HQPlayer, UPnP Server, UPnP Render and other functions. This greatly reduces the system overhead and effectively improves the sound quality.
High-precision, fully-synchronized clock design
For nBridge + products, in the actual listening experience, the higher the clock accuracy, the more direct the clock synchronization, and the better the sound.
nBridge + uses femtosecond-level high-precision clocks, a large number of circuit isolation designs and special FPGA designs to avoid interference and clock accuracy degradation caused by FPGA operations, and effectively guarantee the system clock accuracy.
The big difference from the traditional PC + interface solution is that when nBridge + works, the audio clock used by the ARM board is provided by the digital board, and the decoder clock is also provided by the digital board, which is equivalent to a digital turntable (ARM board) and decoder. Work in synchronous clock state. At this point the sound will be greatly improved. Especially when using IIS connection, the back-end decoder will skip the local clock and directly use the clock provided by nBridge +. At this time, the system sound is the best.
nBridge + 's IIS can easily select the connected decoder through the management page. Due to the new design scheme, nBridge + can publish the new decoder's IIS connection method over the network within a few days of the new decoder's listing or during internal testing. Users only need to upgrade the software online to support the new decoder, effectively avoiding IIS compatibility issues.
It all sounds fantastic! It is simply the guiding light of HiFi! It's like the fireflies in the night, so bright, so outstanding!
Less nonsense, look at things first
If you can accept or ignore the gap in the top cover, this is definitely the top rate shell manufacturing process in HiFi devices made in China. The industrial design is simple and beautiful, and the touch is excellent! Although it is not as good as the aluminum case of the Swiss-made Hifi device that I have touched before, I assure you that this unit has an excellent "feel of quality" to the touch.
I think this texture is good enough for its price over $ 2,100
How I wish I was rich enough to afford it ...
Let's take a look at this diverse interface!
My emotion is over, the microphone is handed over to Apx555B
Here's the duo time for 555B and PNA nBridge!
Jitter Measurement of 44.1K:(following measurements are played using Roon)
Jitter Measurement of 48K:
Jitter Measurement of 96K:
Jitter Measurement of 192K:
For comparison ... Let me test the loopback ...
More comparison a 100usd USB to SPDIF interface
Oh my god ... what did I see ...What an Apple of Sodom ...
