Product Description

Manufacturer's Description:

The NuPrime Reference 20 Mono Amplifier

NuPrime Reference 20 came from the evolution of esteemed NuForce's award-winning Reference amps, after NuPrime has acquired the NuForce high end product line. While the Reference 20 retains all of the Reference 18's superior sonic attributes, the amp’s higher 420W @ 4 Ohm output power brings one closer yet to the goal of supreme performance. The Ref 20's low-ESR Cross Matrix Array (CMA) capacitor assembly features high-performance capacitors in a proprietary, non-resonant alignment. Unifying such refined technology with superior power yields truly unsurpassed speed, transparency and resolution, along with genuinely authoritative dynamics. The net response is a natural, non-fatiguing rendition of music that simply flows from a palpably real soundstage.

 

A pair of Ref 20s in a fine, audiophile-grade system will reveal the following qualities:

  • Thundering dynamics and lightning-fast transient speed

  • Sweeter, more natural highs

  • A near-palpable midrange and overall harmonic structure, resulting in a more natural and relaxed presentation

  • A beautifully textured low end exceeding even that of the Ref 20's exemplary authority and control

  • A deeper, more coherent soundstage

Without a doubt, the Ref 20 is destined to be found at the very heart of any dream audio system.
