British Naim/Name DAC decoder [NewLicensedWarranty]
Naim from the United Kingdom is one of the few Hi-End audio circles who also owns a record company. This brand has a long history of nearly 40 years. The product appearance design has always had its own style. Under the conservative and traditional appearance, there are actually innovative ideas and persistence. For example, they launched last yearHDX hard disk player, Which is the industry leader with two large-capacity hard disks and automatic backupDigital music player, And this digital-to-analog converter to be launched in late September(The model is called DAC), It is also the first product with built-in solid-state buffer memory to achieve "zero time base error" excellent sound performance.
"Zero Time Base Error" Digital Analog Converter(zero S/PDIF jitter digital to analogue)? It is a breakthrough that Hi-End audio industry dreams of. How did Naim Audio do it? It is different from the past digital analog converters which extract and reply the main clock signal from the incoming S/PDIF digital music signal(master clock), Naim Audio’s DAC has a built-in large-capacity solid-state memory, which first buffers and stores the read S/PDIF digital music signal, and then uses a built-in fixed-frequency oscillator to send a stable master clock signal. The time base error that is unavoidable in S/PDIF transmission between traditional digital turntables and digital converters has been eliminated. From another point of view, basically the "memory", "master clock" and "digital conversion circuit" in this DAC digital converter are the same as the "CD record" and "master clock" in a CD player. The relationship with the "digital conversion circuit" is exactly the same. Naturally, there is no time-base error problem of the split digital signal source.
Remove the top cover of the DAC, it can be observed that Naim Audio has always attached great importance to pure and abundant power. It has a built-in 210VA power transformer and as many as 26 sets of regulator circuits for the whole machine. Independent power supply design, players with higher requirements can also purchase Naim Audio''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s dedicated external power supply(XPS or 555PS), So that the sound performance has been further improved. In the core part of the digital analog conversion, the DAC uses a high-speed SHARC DSP digital arithmetic chip, and uses a program written by Naim Audio to perform 40-bit floating point operations and 16 times oversampling processing. The digital analog conversion chip is the same as its flagship CD Two Burr-Brown PCM 1704 like turntable CD555 are processed in parallel.
The body of the DAC is solid and compact, and the terminal group and control functions on the back panel are very complete. It is equipped with 8 sets of S/PDIF digital sound input(2 sets of BNC, 2 sets of RCA coaxial and 4 sets of Toslink fiber), There are also two sets of USB inputs(One for the front panel and one for the back panel), These ten groups of digital inputs each have an independent corresponding precise clock reference. In addition to playing high-resolution digital music files in a USB flash drive, the USB input can also be used for digital connection playback of iPod or iPhone.(Corresponding to digital audio up to 768kHz/24bit, iPod and iPhone support up to 48kHz). On the other hand, the DAC has functions such as two-stage grounding mode switching, DIN and RCA analog output switching, and iPod charging function shutdown, showing Naim Audio''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s insistence on replaying good music.
Naim’s official website finally announced today the technical specifications of the company’s first digital converter Naim DAC. The original manufacturer claims that Naim DAC can completely solve the time-base error and noise problems of previous digital converters. The Hi-End-level design can be called Naim has developed the culmination of CD turntables for many years. The super-complete I/O interface shows that Naim intends to use Naim DAC as the author''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s goal of processing all digital sources.
