Chord Electronics Ultima Pre 3 and Ultima 3 Mono Amplifiers: Masterclass in Speed and Resolution
Posted by The Sound Organisation on Sep 10th 2026
In his review for Hi-Fi+, Alan Sircom evaluates the Chord Electronics Ultima Pre 3 preamplifier and Ultima 3 mono power amplifiers, highlighting the combo as a high-demand standout in Chord’s "Full Size" component lineup. Handcrafted in Kent, UK, this amplifier pairing challenges high-end rivals by delivering exceptional speed, zero noise floor, and dynamic scale without requiring astronomical financial jumps.
Core Engineering & Features
- Ultima Topology: Replacing the long-standing SPM 1400 MkII, the Ultima 3 mono amplifiers output 480W per channel. They utilize Chord's dual feed-forward error-correction system and a sliding Class AB bias that operates in pure Class A during normal listening, switching to Class B only under extreme loads.
- Ultima Pre 3 Preamplifier: A line-level preamp featuring two balanced XLR inputs, three single-ended RCA inputs, an XLR AV bypass loop, and flexible outputs. Input selections are indicated by Chord's signature color-coded glowing central orb.
- Aircraft-Grade Enclosure: Built with precision-machined aluminum chassis available in Jett Black or Argent Silver, configured with integrated "Integra" legs or optional acrylic side blocks.
- Solid-State Performance: Custom MOSFET circuitry provides transconductance performance that combines the speed and drive of Bipolar designs with the refinement of MOSFETs.
Sonic Performance & Characteristics
- Speed & Transparency: The Ultima pairing makes rival amplifiers sound sluggish and veiled by comparison. Complex electronic passages and rapid transient shifts are handled with effortless timing and total clarity.
- Dynamic Headroom & Low Noise Floor: Delivers explosive macro-dynamics and subtle micro-dynamics—such as the acoustic mechanical noise of woodwind keys—against an exceptionally dark, quiet background.
- Proportional Soundstaging: Images scale organically based on the recording; intimate acoustic vocalists sound tight and close, while full orchestral pieces expand into a realistic, dimensional soundstage.
- Refined Tonal Balance: Moves past the clinical presentation of legacy designs into a modern, musically communicative sonic signature that retains pristine detail and vocal nuance.
The Verdict: The Ultima Pre 3 and Ultima 3 mono amplifiers offer an ear-opening, highly resolving performance. By combining blistering speed, low distortion, and authoritative control, this pairing sets a high benchmark for reference-tier amplification.
