音乐传真Musical Fidelity Nu-Vista 800合并功放
该产品入选: 2014/2015年度AVTech Media AWARDS获奖产品榜单 《家庭影院技术》杂志2014-2015年度优秀器材 【展会报道】2017年米兰高级音响展(Milano Hi Hidelity)亮点产品专题 美国《Stereophile》杂志“2018年度推荐器材榜”全部获奖器材 知名杂志《Stereophile》揭晓“2019音响器材推荐榜” 输出功率:330W×2(8欧姆) 输出电流:120Amps(峰值) 输出电压:52V(RMS)@20Hz~20kHz/147V(峰值) 信号输入接口:RCA高电平输入×4对、XLR平衡输入×1对 信号输出接口:RCA、XLR前级输出各1对、4mm香蕉头接口×2对 尺寸(H×W×D):212×483×510mm NU-VISTA 800合并机是音乐传真经典的NU-VISTA系列的延续。NU-VISTA 800糅合了NU-VISTA系列的前级线路,再加上TITAN系列功率放大线路的精华。设计师的目的就是希望得到电于管细腻自然的音质,以及晶体管的强悍驱动力。同时,合并式功放又可以节省一定的使用成本。它就是一种雄浑大气、温暖厚重的声音,驱动很多类型的音箱都显得得心应手。 Nu-Vista 800为大功率设计,在8欧姆负载下能输出330W的最大功率,能驱动市面上绝大部分的音箱。Nu-Vista 800的后级部分电路设计来源于TITAN系列后级,前级部分则是以前的Nu-Vista前级线路,而且左右声道完全独立供电,能把控制力和音色都做到一个比较好的状态。而Antony Michealson为了证明NuVista 800的实力,还特意地给我们展示了Nu-Vista 800的部分实测数据,例如:10V输出且测试频率在1kHz、10kHz、20kHz测试信号下测得的失真率分别为0.0025%、0.0030%和0.0040%,频响曲线在人类可听的范围内近乎直线。同时,Antony Michealson还特别强调,Nu-Vista 800的线路设计并没有依靠深度负反馈来获得高性能,而是通过元件自身的特性及线路设计实现的。 Amplifier Power output: 330 Watts per channel into 8 Ohms THD (+ noise): <0.005 % typiclal 20Hz - 20 kHz Signal to Noise Ratio: >107dB 'A' - weighted Frequency Response: +0, –0.1dB, 10Hz to 30 kHz Line Level Inputs 4x Line Level RCA / Phono 1x Line Level XLR Balanced Line Level Outputs 1 pair line level RCA connectors, constant level LINE outputs 1 pair line level RCA connectors, PREAMP outputs for e.g. biamping Speaker Level Outputs 2 pairs 4mm banana plug/binding posts Power Requirements 115/230VAC 50/60Hz (factory pre-set) 100VAC 50/60Hz (alternative) Power Consumption 130W on and idle (blue LED lit) 900 Watts maximum General Dimensions - WxHxD (mm): 483 x 187* x 510 *212mm on included optional pointed feet Weight (unpacked / packed): 39 kg/ 47 kg The Nu-Vista 800 is a power-house of an amplifier with outstanding clarity and finesse. Overview For the first time in the history of hi-fi, Musical Fidelity have combined nuvistor technology with Surface Mount Design and CAD/CAM PCB concepts. The aim of this large undertaking was to create an ultimate super integrated amplifier. The result is extraordinary technical and sonic performance. For Musical Fidelity, the NuVista 800 integrated was a labour of passion and love. We have tried to achieve the absolute maximum performance from every part of the circuit. The NuVista 800 integrated offers full-on, high-end performance, in a beautiful, relatively compact package, and gives a comfortable 300 watts per channel. The NuVista 800 delivers everything that its concepts promise. On the one hand, you have the beauty and warmth of nuvistor tubes. However, because of their superlative technical performance, there is no colouration or excessive warmth. On the other hand, there is a huge power amp with massive reserves of power and current that has the delicacy and speed of attack (and decay) of a small triode power amp but, just you wait for that transient:it is delivered effortlessly with no colouration or limits. The NuVista 800 sound quality is, to us at least, totally satisfying.Beautiful, deep and wide sound staging, effortless transients, incredible bottom end extension, speed, rhythm and then the exquisite mid range. We believe that this is what hi-fi is about. Design and Build Fifteen years ago, Musical Fidelity were the first company in the world to use nuvistor tubes for their high-end NuVista series. The original NuVista series (NuVista pre amp, NuVista M3 integrated, NuVista 300 power amp and NuVista 3D CD player) created a sensation when they were launched in 1999. They gave an almost perfect balance between state of the art transistor and tube design. Because there were only limited tube bases available in 1999, the NuVista series were all made in limited editions.Their reputation is legendary and, to this day, used NuVista series products for very high prices. Background on nuvistors Nuvistor tubes were designed in the late 1950s. Their design process took into account all the criticisms and weaknesses of the standard glass tubes that had gone before. As a result, nuvistor tubes offered: Unprecedented reliability Compact size Very low microphony State of the art technical performance Total consistency between manufacturing batches Indeed, nuvistors were the ultimate, high performance, triode tube. Unfortunately for them, transistors were just coming of age as nuvistors became available. A bright new dawn For at least three years after the launch of the original NuVista series, Antony Michaelson tried to get more tube bases. Nuvistor tubes were plentiful but bases were impossible to obtain. After a time, he stopped searching. As many of you know, Antony Michaelson is persistent. About eighteen months ago, he started thinking about NuVistas again. This time, things were different. Via the internet, he was able to locate what are probably the last nuvistor bases on this planet Earth. Antony was thrilled. He purchased all that could be found. This made it possible for Musical Fidelity to realise their dream of manufacturing more nuvistor-based products, including the new mega super integrated, the NuVista 800. This time, they would be able to combine their state of the art NuVista technology with their state of the art Surface Mount Design PCB techniques, and the new designs would benefit from the freedom of layout that they offer. General description The NuVista 800’s front end is positioned on the same PCB as the input circuitry. This keeps all PCB tracks as short as possible, and ensures that this highly sensitive function is at right angles to any stray hyseresis field from the transformers, ensuring superlative sonic performance. The nuvistor stage itself combines nuvistor tubes with our exclusive Surface Mount Design and technology systems. This allows them to perform at a level never seen before. The power amp stage is derived from our monster Titan amp, regarded by many as one of the best amplifiers ever made. However, they have made subtle improvements to the circuit, squeezing even more performance from what was already a legendary circuit design. The overall configuration is dual mono, with a separate 1.5 kV, super silent drive mains transformer per channel. The result -maximum performance from every part of the circuit- clearly shows just how much of a labour of love and passion for the NuVista 800 was for us. Technical performance The NuVista 800 delivers a comfortable 300 wpc. It is capable of truly massive current swings: about 200 Amps peak to peak. In a word, vast. Distortion at 1kHz is vanishingly low at 0.002%. At 10 kHz, it is about 0.003% and at 20 kHZ 0.004%. These are extraordinary figures. More astonishingly is the distortion into 4 Ohms (1kHz) is its exactly the same is into 8 Ohms. NuVista 800 has very low noise and excellent stereo separation. Because of its huge peak current capability, it can drive any speaker with any cable, without breaking a sweat. NuVista 800 combines the beauty, delicacy and poise of state of the art tube and semiconductor design blended with massive power and current.
