Ayre Acoustics MX-R Twenty Monoblock Amplifiers — Pre-Owned Pair

Overview

Here is a wonderful pre-owned pair of Ayre Acoustics MX-R Twenty monoblock amplifiers — truly one of the great achievements in high-end audio. These beautifully built monoblocks have been enjoyed for approximately 12 years and are offered in excellent condition, rated 7.5–8/10, showing only minor cosmetic blemishes and small scratches consistent with careful long-term ownership. Sonically, they are everything you would expect from the MX-R Twenty: authoritative, musically refined, and capable of driving virtually any loudspeaker to its full potential.

Finished in desirable black and machined from solid billets of aircraft-grade aluminum, each amplifier delivers 300 watts into 8 ohms — with the current reserves to double output as impedance halves. Their fully balanced, zero-feedback architecture brings a naturalness and tonal richness that is genuinely difficult to find in amplifiers of this power class.

Each unit is carefully demonstrated and inspected before purchase. A local Southern California sale is strongly preferred. Sunny's will include professional delivery and in-home setup for buyers within 50 miles.

Press & Reviews

Stereophile found that the MX-R Twenty stepped out of the way and allowed music to flow naturally — with an exceptionally low noise floor and extremely wide bandwidth confirmed in measurements.

SoundStage! Ultra praised the Twenty for its increased tonal body, warmth, low-frequency presence and direct connection between source and loudspeaker — achieving greater clarity without brightness or an etched quality.

These observations closely match what we hear at Sunny's: superb drive, sweet tonality, powerful bass and an unusual ability to maintain musical refinement even while controlling a demanding loudspeaker.

Bundle Opportunity — Add Magico S5 Loudspeakers

These amplifiers were previously paired with a set of original Magico S5 loudspeakers — a three-way, sealed aluminum enclosure with a 6-inch Nano-Tec midrange and dual 10-inch woofers. Together they form a carefully matched, full-range reference system from the same era.

• Ayre MX-R Twenty monoblocks: $15,750/pair
• Magico S5 loudspeakers (also available): $18,500/pair
• Complete system: $37,000 — hear both together before you buy
