不时会看到一些人对北极星解码器的误解甚至是来自于个别人别有用心的误导,我认为有必要在此给予北极星解码一次公正的评价(我和北极星并无任何的利益关系)。

其实国内烧友普遍有个通病,就是喜欢音响器材里有五颜六色的电容阵,人云亦云,却没耐心去看看人家北极星是如何去设计低噪音供电电路、低Jitter USB/数据电路以及精密的模拟输出电路。就算真要算起电容的数量,加上贴片电容人家可是数倍于您,其实稍微用高档的示波器就能看出那素质上天与地的差别。

我不认为Benchmark DAC2, Mytek 192、DA8、Wadia 121等机器能比得上北极星Excelsio或Supremo。

众所周知,解码器好声的根源在于对供电和模拟电路的重视,数字输入部分现在大部分解码都已经做得很好了(虽然很多解码的数字部分供电还不行)。新一代北极星采用高成本的Atmel ARM+CPLD USB输入模组也不是一般只会使用公版XMOS模组的解码可比的。

从电路学上来说,北极星Excelsio/Supremo供电和模拟电路在厂机里也是数一数二的,大面积的模拟输出电路,完全独立的双变压器给数字部分和模拟部分独立的供电,将近十个数字和模拟部分小模组都各自有独立无干扰的高性能稳压模组供电,Benchmark、Mytek、DA8甚至是Vega有吗?要在他们那么小的机箱里塞入那么多独立稳压模组还是有物理上的限制的。要找出好的解码,对电路设计有最起码的认识还是必须的,而不是靠人云亦云和玄乎乎的所谓“听感”。也许很多明知道机器的电路设计和用料比不过人也只好用“听感”来蒙混过去了。其实打开机箱看看电路板一切都一目了然了,难道我们就不能有自己的独立思考能力和辨别能力吗?

Mytek、Benchmark等那相当阳春的供电和模拟输出设计也能出好声?只能说这些解码的用家喜欢刺激性的机器,而不是高素质的机器。

北极星对乐器余韵的呈现在国际上可是赫赫有名的(在解码器界乐器余韵是公认最难正确回放的声音)。它是一个能让你静下心来安心真正听音乐的解码,在台湾、韩国、日本和欧洲都是个红透半边天的产品,用料和声音素质都能得到用户应有的好评。反而国内烧友浮躁和人云亦云的气氛却让这么好的机器无辜背上了莫须有的恶名,致使众多入门烧友错过了那么好的机器,令人惋惜。

North Star Design Impulso DAC Preliminary Review
- a translation from an Italian press

Great efforts have been made in the house then North Star which has thus renewed range of products dac. In practice, the Excelsio replaces the Usb Dac 32, the Supreme replaces Extremo. Remain for the moment still in production Essensio, plus Essensio and Fluxio.

Then we are going to test the smallest of the new triad with renewed interest in the new products of the great Italian brand, interest even more exacerbated by the fact that the holder of NS had announced new products with his personal satisfaction with the quality achieved. Knowing so many years Giuseppe Rampino, that person is cautious and calm, it was the first time that he himself was quite warm a presentation of its new product. It 'so much curiosity, augmented by the expectation of a few weeks and the fact that not so long ago we had already tested with great satisfaction the other two converters of the same brand.

Aesthetically, the new pulse is similar in size all'Essensio, or small sizes, 30 x 17 x 7 cm. Change only the chassis of polished metal, now better finished, and the bigger screen size.

Very few of the commands available in practice only two, namely the stand-by button and input selector, which in this case are 5 inputs, or two digital coaxial and two optical and a USB. As nell'Essensio is not present the I2S input.

The outputs allow the connection in both balanced and unbalanced in. In the display, which informs us about the selected input, there is a blue LED that tells us when a signal is received in DSD format. In this regard, the frequencies are recognized to 44.1 khz and 48 khz. From the instruction manual we learn that it is possible to operate some adjustments on the PCM signal filters, settable in Lo and Hi and DSD, staring at the band - 3 db at 47, 50, 60, 70 Khz. E 'can also change the phase: 0 or 180 °.

The big news is the ability to be able to use software to DSD 352.8 to 384 khz via the usb input. More and more sites with files to DSD (Direct Stream Digital) See for example the website of Channel Classic Records which has an excellent catalog.

For the PCM instead of the bit rate can go up to a frequency of no less than 384 kHz 32-bit.

Are attached to the product, as well as the instruction manual, also a guide to the configuration of the most popular software used with Mac or Windows. For Mac users have instructions for Audirvana and Pure Music. For Windows users have the instructions on the best setting JRiver and Foobar 2000. These details should cover also the part relating to the reading of DSD data.

We connect the cables to the pulse output signal, connect the power supply, and then connect our PC with Windows 8 after inserting the CD into the computer attached to the packaging as indicated in the instructions. We note immediately that the PC retrieves the drive, install it and recognize it. We open Foobar and 「preferences」 in 「output」 retrieve the new WASAPI device for digital output (PCM-DSD Audio Interface). Perfect, everything went like clockwork.

Do not miss that choose a file, pardon a piece of music to go listen.

We compare the direct pulse with a North Star Extremo using usb interface - i2s and the rest of the system consists of Ensemble Evocco amplifier, speakers Triangle Magellan Cello, signal cables and MIT MI 350 Twin Power MIT Matrix 28 .


The impressions? Exciting. The first consideration is that we do have now made real progress for playing music and if liquid until a short time ago the gap in quality between the music played from a CD and streaming music was, for many people, still pro- reading the cd, now, thanks to the development of new technologies, or new drivers, the levels are almost reversed, and more and more people are easily able to get higher quality reproduction by means of a PC.

We do not want to overdo it with praise and superlatives but we still want to share with you that the ability of this small converter details.

We are facing an extraordinary product, which is surprising with regard to the impact, dynamics, timbre, the image of the sound stage, sense of rhythm, the ability to play complex musical moments with ease. This is due to a jitter practically absent.

Very low distortion and exciting the explosive force. We listened to a Rite of Spring with a burst absolute that has left us stunned.

Excellent items which are reproduced at a height higher than usual with good naturalness.

All this translates with the desire to raise the volume even more, and then it seems that our amplifier will be revitalized with an irrepressible energy hitherto unknown and we thought unattainable. The energy there he was, already available, just needed a more powerful source capable of detonating it in its real capacity.

All this by simply using files at 44.1 or files in high definition. When playing DSD files instead, or by applying the standard of the Super Audio CD, the performances increase even more, and then we enter the field of the absolute regardless of category.

We do not understand what was the chemistry that has allowed the achievement of these results, it is certain that we must congratulate Giuseppe Rampino has been able to renew its range of devices with increased quality of products. Certainly the new processors ESS Sabre ES9016 play a vital role.

The studies and research, the result of the passion and expertise of the technical staff of North Star have allowed obtaining a great achievement that brings honor to the high fidelity Italian.

And if the other two new devices Excelsio and Supreme proportionately keep these standards will be real quality standards and will be able to confirm once again the superiority of the brand North Star, as happened in 2001 when it was first introduced the Model 192 was confirmed that a real best seller. The price of Impulse is 1,350 Euro.
