Nubert NuPower A in the Test

Nubert has done it again. Inspired by the high response to its first digital power amplifier, he pushes to the analog-amp nuPower A. The 42-kilo – colossus is a “Manifescht” Swabian art of engineering. But how does he sound?

Only in the last year Nubert let. The boxing specialist from Swabian Gmund stood with his/final combination of nuControl/nuPower D / test and earned much recognition.

That meant a big step for Nubert while the vitale fanbase itself but only a relatively small. Finally, the direct mailers offers already sophisticated electronics accessories such as the ATM module compact boxes bass tuning. But above all, he gained plenty of experience in the construction of the amplifier in its active speakers. Little wonder therefore, that after the successful launch of digital Combi more components follow.

With the brand new nuPower A turns Nubert on analog disciples. May be also so efficient class D amplifier, there are still arguments for the proven analog technology. A typically lower noise level. A point that did not give rise to the criticism but the nuPower d. On the other hand decreased sensitivity to high and low impedance that cause the most digital amplifiers sometimes significant variations in the frequency response.

But even that was not an issue at Nuberts first. However, also the Swabian inventor could achieve not performance bandwidth of good transistor amps, which among other things related to the topic of noise shaping.

Freedom of choice

With the advent of the nuPower A we finally with free choice, as we our signal hardware from Schwäbisch Gmünd want to strengthen. While the decision means a voluntary renunciation of self at the maximum power for Nuberts analog raw – for owners of far eastern mass-produced amplifier one can speak it quite luxury worries-, but there are full bandwidth from DC up to the end of the measuring range at 100 kHz.

Development director Markus pedal trying to understand the arguments for both technologies funded by him: “even if power amplifiers are proven OFF-principle for a long time – you could almost say:, Old School’-class D now sound has moved and just our opinion, wanted to we demonstrate what get out of this principle can be if you consistently and with high component costs to implement it.” In some readings the nuPower A nuPower D is not only equal, but even more superior.” Thus, the creator aims to the greater stability of the load and the aforementioned bandwidth.

Lead developer Markus pedal has created a high-quality amplifier with practical concept: the fine thread terminals for two pairs of speakers can be toggle on the front. Toggle switch on the back change the operating mode or the inputs.

Another argument: can the new bridges is in contrast to the nuPower D for Mono operation. It offers flexibility in terms of future system expansion. Because pedal stressed, you have the best class-OFF principle through careful selection of components and highest quality workmanship implemented as sustainable, that the nuPower A is still indemnify perform his service in 20 years. As an example-driven effort is called the Chief developer of MOSFETs for the performance level of the fully symmetrical built Klasse-AB amplifier would be produced only by a manufacturer in the world with the required specifications.

A stated objective of the development was in compliance with the 43 cm standard width, because the Swabian wanted to produce no “Monster block” by his own admission.

The two-storey nuPower A offers mass and class at a moderate price. Its side walls are designed as a heat sink for the performance levels mounted on it. The two power transformers can stay in an own shielding enclosures under the power supply Board with their high temperature solid electrolytic capacitors.

Heavy metal

To achieve this goal in connection with the rich output of almost 500 watts RMS per Channel 4 ohm, without compromising the temperature balance of the power amplifier, designed not only the side walls of the rock-solid full metal case as a heat sink. Also the two-storey building and the interpretation of the Board aimed at contributing to the good working climate in the Interior of the 42 kilo cars rack-friendly size. And if but once hot should be made in the heat of battle, the clever Swabians have built before. Pedal calmly faces all the challenges of everyday life: “Our electrolytic capacitors for example have even at 85 degrees Celsius a guaranteed lifetime of several thousand hours.”

When designing Nubert placed emphasis on perfect harmony with the in-house prepress nuControl, which leaves nothing to be desired in terms of setting possibilities. Not for nothing the Gmunder praise it as “Sound Manager and Speaker optimizer “. Foreman meets this requirement through a Seven-volume part of parametric equalizer, allowing targeted sound corrections between 20 and 20,000 Hz. You can also set crossover frequency, slope and delay for subwoofer.

Naturally the nuPower A as output stage when it comes to features with a such precursor can’t keep, but given the modest price of 3650 euros, the product planners at its generous showed. And this is not only because that his price per kilogram rather is comparable to of high-quality beef, as with the truffles – what ever may occur under thick amps from overseas.

Finds completion anywhere

Nubert was giving its analog-amp pair stereo inputs for RCA and XLR connections, and a speaker selector, which allows also the parallel operation of two pairs. The fathers of nuPower A on their fine threaded terminals for the speaker outputs that can make themselves fat 6 mm stripping right in the lack of pride.

Listening test: The moment of truth

In the listening room, the tester took Nuberts new right to cross-examine. D and the Avantgarde Acoustic UNO XD, he had to prove themselves with several speakers, including the Gauder acoustics Cassiano MK II. It pricked his unyielding control in the bass in the ear. Regardless of the loudspeaker, he helped to a crisp, powerful performance with very dry swinging out of bass drums. Obviously, the Swabian in terms of damping factor left burn anything.

Also convincingly he ensured even in the extremely jagged sound that enough space to unfold on the wide sound stage got to every instrument and every voice and learned the same attention to detail. This came major orchestras such as the London Symphony Orchestra (LSO) played a benefit as well as live rock music by toto (“XX”) or the Eagles (“Hell freezes Over”).

All virtues of the nuPower A came independently from the transducer to bear. Even if the connected speakers like the Gauder with low impedances challenged him, he remained faithful to his good habits. The less good also: he showed even the cool shoulder – votes, just if it is women’s voices or high male voices such as that of upper-Eagle Don Henley was.

It had somewhat of a power athlete who has tried his hand as a ballerina. So he took the tender melt of their resolve filigree diamond tweeter even the Cassiano. If it is not primarily to punch, but a harmonious, the digital nuPower D proving the consistent solution.
