Nuprime MCX-4

This product is no longer available for sale!

Overview

The creation of the NuPrime X brand aims to introduce NuPrime technology and sound through gaming and home cinema. Whether you’re watching a movie, a live concert or video games, the MCX amplifier, with its ultra-fast dynamics and extremely low distortion, allows you to reach a new level of audio realism.

Taking full advantage of NuPrime’s award-winning products, the MCX has been developed for the multichannel market. The MCX uses NuPrime’s Class A+D hybrid amplification technologies that provide the substance and warmth of Class A amplification as well as the efficiency and speed of Class D technology in an environment of immeasurable noise.

A 1,000 W power supply and a set of 33,000 uF CMA capacitors allow the MCX to fully exploit the capacity of the Class A+D design to deliver huge amounts of power and speed when needed on one or more channels.

The MCX amplification circuit improves on the traditional Class D design by using a self-oscillating circuit to generate pulse width modulation. The amplifier switches at a frequency of 550 kHz, well beyond the 44.1 kHz sampling rate of the compact disc.

User reviews

Jean-Pierre

Very satisfied with this power amplifier for my Denon 8500 HA Home Cinema installation and Triangle Signature speaker package. I'm powering my two floorstanding speakers and two surrounds. Works well with Denon's sound signature, notably bringing a beautiful powerful and musical sound to the floorstanding speakers with a touch of smoothness that is very enjoyable for music listening. Compact size (which is what I was looking for) and good value for money in terms of sound quality. Versatile for both music and movies.

Très satisfait de cet ampli de puissance pour mon installation Home Cinéma Denon 8500 HA et pack enceintes Triangle Signature, j'alimente mes deux colonnes et deux surround. Fonctionne bien avec la signature sonore Denon, apporte notamment sur les colonnes une belle sonorité puissante et musicale avec une composante douceur qui est très appréciable pour les écoutes musicales. Faible encombrement (c'est ce que je recherchais) et bon rapport qualité sonore prix. Polyvalent musique et films.

Replacing a Harman Kardon AVR 8500, of which only the power amps were used with an Anthem preamp.
In comparison, the NuPrime is more energetic than dynamic, with less control and foundation than the 8500, and the timbres are less well respected.
Watts are nice but don't make for musicality.
That said, it has a small footprint and doesn't generate much heat.
I don't understand the purpose of the XLR and RCA selectors because even if the selector is on RCA, the XLR input works... and vice versa...
Too bad the power consumption is 20 watts with the trigger connected (according to on-mag...).
Works well for surrounds, which is how I use it.
There are better options but they're more expensive!

En remplacement d'un Harman kardon AVR 8500, dont seul les amplis de puissance étaient utilisés avec un préampli Anthem.
En comparaison, le nuprime est plus énergique que dynamique, moins de contrôle et d'assise que le 8500, les timbres sont moins bien respectés.
Les watts c'est joli mais ne font pas la musicalité.
Ceci dit, faible encombrement et chauffe peu.
Je ne comprends pas l'utilité des sélecteurs xlr et RCA car même si le sélecteur est sur RCA l'entrée xlr fonctionne…et vice versa…
Dommage que la consommation soit de 20 watt avec le trigger connecté (d'après on-mag…).
Convient bien pour les surrounds, j'en fait cet usage.
Il y a mieux mais c'est plus cher !

I bought two of these to replace a large Onkyo. The sound quality is excellent - I compared it on the center channel powered by an Accuphase Class A amplifier.
These NuPrime speakers are surprisingly warm and well-defined. They have nothing to be ashamed of.
I just hope their reliability is also up to par.

J’en ai pris deux en remplacement d’un gros Onkyo. La qualité sonore est excellente, j’ai comparé sur la voie centrale alimentée par un accuphase classe A.
Ces nuprime sont surprenants de chaleur, et de définition. Ils n’ont pas à rougir.
Souhaitant que la fiabilité soit également au rendez-vous.
