J'ouvrirai un post dès réception, mais le MCA-20 est dispo en test. J'en sais donc un peu plus sur leur spécifications et il intègre un filtrage numérique PCM/PWM (peut être 844 khz / 35 bits comme le NAD M-51, donc peut être une puce Zetex DDFA ...). Il y aurait deux versions (front flat panel) 1499€ TTC et (stealth) 1750€ TTC.
The NuForce MCA-20 multi-channel amplifier offers the dedicated enthusiast eight channels of signature NuForce sound. The MCA-20 was developed as an audiophile-grade alternative to the plethora of consumer-grade amps being offered for Home Theater applications. With its top-quality parts and advanced, high-efficiency switching technology, the MCA-20 delivers genuine NuForce performance and value.
The MCA-20 delivers a full 278 Watts into 4-Ohms per channel and owes its pedigree to NuForce’s award-winning V3 series of mono amps. In keeping with its stellar relatives, it renders all of your recordings and sound tracks with thundering lows, crystalline highs, and a warm, tube-like midrange - all in perfect balance.
The MCA-20’s proprietary feedback circuitry operates as the cornerstone of the MCA-20’s remarkable sound. A self-resonant design, the 400 kHz PWM switching frequency constantly adjusts to the input signal, output current demands, and loudspeaker impedance variations, resulting in superb speed and accuracy. The MCA-20's crystalline reproduction of the most explosive dynamics united in harmony with the minutest of sonic details guarantees that you'll always experience the same life-like presentation upon which NuForce’s reputation rests.
To be sure, the MCA-20 is destined to find its place as the driving force in a great many music and A/V systems. When it comes to mating with today's modern Home Theater components, the MCA-20’s power, transparency and sophistication defy the competition at its price point. Where sound performance and value matter, nothing less will do.
Innovative features include:
- High power – 278 Watts per channel x 8
- Modest size and modern construction
- Proprietary high-speed, negative feedback design
- Very high efficiency PWM circuit topology
