A 250,000-microfarad capacitor bank inside a single stereo power amplifier is not a figure you see often, even at the very top of the high-end market, but that's what drives this build - the CH Precision M1.1 feeding the Peak Consult El Diablo, a three-way Danish floorstander Hifiverse describes as letting speakers "completely disappear into space" and "leave the listener alone with the music."
The system at a glance
Four components, all from CH Precision's electronics range paired with a single flagship Danish loudspeaker, and a Munich 2025 show installation Hifiverse rated for "large-scale dynamics and powerful bass." This is a reference-tier system built to demonstrate what happens when a massive amplifier power supply meets a loudspeaker specifically voiced to disappear as a physical sound source.
Why these components work together
The El Diablo is a three-way design playing from 20Hz with a sensitivity of 90dB into a 5-ohm load and weighing a substantial 90kg per cabinet, a specification that calls for genuine current delivery rather than sheer voltage swing to control its bass section properly. The CH Precision M1.1 answers with 200 watts into 8 ohms, running its driver stage in pure Class A from a fully discrete circuit topology, backed by a 2,200VA transformer and that 250,000-microfarad capacitor bank, a power-supply reserve considerably larger than most amplifiers at any power rating carry, giving the M1.1 the ability to sustain current delivery into the El Diablo's demanding low-frequency section without the power supply itself becoming the limiting factor during heavy bass passages. The CH Precision L1 preamplifier, a fully discrete, dual-monaural line stage with heavily regulated and filtered power supplies of its own, keeps the signal quiet enough that the M1.1's considerable Class A headroom translates into genuine dynamic range rather than amplified noise, while the C1.2 DAC's linearized R-2R architecture, four PCM1704 chips per channel arranged in an upsampling, volume-controlled topology, gives the whole system a source capable of the same resolution the amplification and loudspeaker are built to reveal.
How it sounds
Hifiverse's own verdict from the Munich show floor, large-scale dynamics and powerful bass, tracks directly with the underlying engineering - the El Diablo's 20Hz extension and 90dB sensitivity give the M1.1's substantial current reserves genuine work to do, and the result is a loudspeaker that reviewers and show visitors alike describe as disappearing as a physical object, leaving only the music and the room it fills

El Diablo
by Peak Consult
The speakers completely disappear into space and leave the listener alone with the music, revealing sacred secrets and demonstrating the entire palette of antisocial shades of the author's performance. The three-band system plays from 20 Hz, has a sensitivity of 90 dB, a resistance of 5 ohms and weighs 90 kg.
