The NuPrime Audio Reference 20 Mono Block Amplifier

Music lovers have long esteemed NuPrime's award-winning amps for the clarity they bring to the source. Those qualities that set NuPrime amps apart --  superior resolution, transparency, dynamic finesse, harmonic integrity, and the projection of a precise, well detailed soundstage --  have advanced incrementally to our most recent crowning achievement in amplifier technology, the 17"-wide NuPrime Reference 20.

Based on the highly acclaimed NuForce Reference 18, the NuPrime Reference 20 builds on past success and offers greater power, depth and clarity.

"The Reference 18 is hands down the finest amplifier NuForce has made, and I think it is good enough that it deserves to be included in most any discussion of top-tier amplifiers. Even if you have heard (and perhaps disliked) Class D amplifiers in the past, this is one I think you will find worthy of your time and consideration. Above all, the Reference 18 keeps faith with the truth of the recording itself, which is all anyone might ask of a fine power amplifier."

Design & Features

While the NuPrime Reference 20 retains all of the NuForce 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 NuForce Reference 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.

In addition to the NuPrime Reference 20's performance gains, the amp retains the same advanced feature set and elegant style as the NuForce Reference 18, including premium WBT speaker binding posts. In addition, a 12-volt On-Off trigger input enables it to be controlled from within the framework of any premium installation, be it two-channel, home theater, and other domestic or commercial applications. As always, the NuPrime Reference 20 can be mixed and matched with other NuPrime models for bi-amp and multi-channel operation.

The Sound

The NuPrime Reference 20 elevates the already excellent performance characteristics of the NuForce Reference 18 -- most notably, liquidity and neutrality -- to a degree that must be heard to be believed. As with the NuForce Reference 18, operation in a less than well-resolved and transparent system may mask the NuPrime Reference 20's advantages.

Conversely, a pair of NuPrime Reference 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 NuForce Reference 20's exemplary authority and control
  • A deeper, more coherent soundstage

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