Clarus Concerto MKII Power Conditioner: High-Current, Low-Noise AC Solution Assessment Review
Smart application-specific filtering for Analog, Digital, and High-Current outlets to reduce line noise, yet without compressing the music's dynamics
AXPONA 2025 Luxury Hi-Fi Audio Show Report By Steven R. Rochlin

  Clarus just showcased their new Concerto MKII, a next-generation eight outlet power conditioner engineered to cut electrically induced noise while preserving the music's dynamics, audio tonal density, and musical detail that high-performance hi-fi systems demand. Building on the original Concerto, the new MKII raises the bar with higher current capacity, refined filtering architectures, improved grounding, and enhanced power distribution. Clarus positions the MKII not as a blunt noise suppressor but as a carefully balanced electrical foundation that lets connected components perform without compromise.

At the heart of the Concerto MKII is Clarus's application-specific filter architecture and the proprietary Clarus FluxCore nanocrystalline inductor technology. The unit separates outlets into Digital, High Current, and Analog banks, each served by tailored combinations of common-mode and differential-mode filtering so that sensitive analog circuits receive low-ground referenced noise suppression while high-current outputs deliver large transient currents without added series resistance. New oil-filled capacitors improve thermal stability, and a full 20-Ampere internal design, star ground topology, heavy-gauge copper bus bars, and a hydraulic-magnetic breaker ensure the conditioner never becomes the weak link in a demanding system. As engineer Jay Victor explains, "The MKII takes a different approach by targeting acoustically destructive noise while preserving the dynamics and harmonic structure that make music feel alive."

Clarus' Concerto MKII's philosophy shows clear results: background noise drops, low-level detail and inner tonal harmonics emerge, and complex passages gain improved clarity and instrument separation, yet without any sense of compression, strain, or loss of musical vitality. Bass seems to become tighter and more authoritative, as the transient definition sharpens, plus the overall soundscape opens with a more natural immersive sense of space. Unlike conditioners that achieve quiet by constraining or limiting current, the MKII preserves transient headroom and tonal richness, so recordings retain their intended weight and emotional impact while unwanted electrical artifacts recede.

Priced at $12,000 (not including power cable), Clarus' impressive new Concerto MKII targets serious audiophiles, music lovers, immersivephiles, and AV professionals who view power quality as integral to overall system performance. Clarus' constrained-layer damping and robust mechanical design also address mechanically induced noise, further stabilizing electrical behavior under real-world conditions. For systems where every nuance matters, and you desire the very best, Clarus' Concerto MKII promises measurable engineering advances and audible improvements—delivering a low noise, high-current platform that aims to make the music feel less like it's being powered and more like it's musically flowing forth.

As always in the end what really matters is that you...

 

Enjoy the Music,
