Chord Electronics ULTIMA Pre 3 Preamplifier at Vinyl Sound Toronto Canada

The ULTIMA Pre 3 is a line-level stereo preamplifier from Chord Electronics (Maidstone, Kent, United Kingdom), available at Vinyl Sound in Toronto, Canada. Designed by Chord Electronics founder John Franks, the ULTIMA Pre 3 is the entry point into Chord's full-width ULTIMA preamplifier range, built around advanced low-distortion power supplies, fully buffered inputs, and unity-gain amplification to deliver an extraordinarily low THD of 0.002%, a signal-to-noise ratio of -105 dB on all inputs, and a frequency response extending to 200 kHz. With five individually buffered analogue inputs, AV bypass functionality, a redesigned aircraft-grade aluminium chassis, and a universal auto-switching power supply, the ULTIMA Pre 3 is one of the most transparent and precisely engineered preamplifiers available at its level.

Advanced Low-Distortion Power Supplies and Unity-Gain Topology

At the core of the ULTIMA Pre 3 is Chord Electronics' latest generation of advanced low-distortion power supplies, designed to eliminate noise at the source rather than filtering it downstream. These proprietary devices provide an exceptionally clean power foundation for the active gain stage, contributing directly to the preamplifier's measured THD of 0.002% across the full 20 Hz to 20 kHz audio band and its -105 dB signal-to-noise ratio across all five inputs. The ULTIMA Pre 3 operates at unity gain, meaning its gain factor is x1: the preamplifier passes the signal from source to power amplifier without adding any amplification, preserving the complete integrity of the source signal while the volume control manages level. This approach, combined with an output impedance of just 560 ohms and a maximum output voltage of 17 V RMS, ensures the ULTIMA Pre 3 can drive any power amplifier with authority while remaining entirely transparent to the character of the source. The universal auto-switching mains supply operates across 80 to 250 V AC, ensuring complete compatibility with North American and international power standards.

Five Individually Buffered Inputs, AV Bypass, and Redesigned Aesthetic

The ULTIMA Pre 3 provides five analogue inputs, comprising two balanced XLR pairs and three unbalanced RCA pairs, each individually buffered and selectively filtered against radio frequency interference ingress. Individual buffering ensures complete electrical isolation between inputs, preventing any interaction between connected sources and maintaining signal purity regardless of which input is active. An AV bypass input allows the ULTIMA Pre 3 to integrate cleanly into home cinema systems, passing the signal from an AV processor at unity gain without engaging the volume control. A front-panel balance control and an AV bypass selector flank the central circular power sphere, both fitted with Chord Electronics' latest ergonomic knob design. The chassis is precision-machined from aircraft-grade aluminium and accepts the included Integra legs for standard orientation or optional Side Blocks for a lower-profile installation, though Side Block configuration does not support stacking. A 5V USB Type-A charging port on the rear panel accommodates mobile device charging without requiring a separate power outlet.

Frequently Asked Questions

What is the Chord Electronics ULTIMA Pre 3?

The Chord Electronics ULTIMA Pre 3 is a line-level stereo preamplifier from Chord Electronics, a British high-end audio manufacturer based in Maidstone, Kent, UK. It operates at unity gain (x1), features five individually buffered analogue inputs across two balanced XLR and three unbalanced RCA connections, and achieves 0.002% THD across the full audio band with a -105 dB signal-to-noise ratio on all inputs. It is the entry-level full-width preamplifier in Chord's ULTIMA range, designed to pair with the ULTIMA 5, ULTIMA 6, or the ULTIMA monoblock power amplifiers, and has received five-star ratings from What Hi-Fi? in both 2022 and 2023.

How does the Chord ULTIMA Pre 3 compare to the Naim NAC 282 or Bryston BP-17?

The Chord ULTIMA Pre 3 competes directly with preamplifiers such as the Naim NAC 282 and Bryston BP-17 Cubed in the high-end analogue preamp segment. The Naim NAC 282 is deeply integrated into the Naim ecosystem and requires external power supplies such as the Hicap DR for optimal performance, while the ULTIMA Pre 3 is a self-contained unit with its own advanced internal power supplies and no external supply dependency. The Bryston BP-17 Cubed offers a 20-year warranty and a similar line-level focus, but the ULTIMA Pre 3's 200 kHz frequency extension, 100 dB channel separation, and 0.002% THD represent measurably higher technical standards. What Hi-Fi? awarded the ULTIMA Pre 3 five stars in both 2022 and 2023, describing it as class-leading for clarity and insight.

Can the Chord ULTIMA Pre 3 be used with non-Chord power amplifiers?

Yes, the Chord ULTIMA Pre 3 works with any high-quality power amplifier. Its 560-ohm output impedance and maximum output voltage of 17 V RMS ensure it can drive the input stage of virtually any power amplifier without difficulty, regardless of manufacturer. StereoNET noted in its Applause Award review that the ULTIMA Pre 3 "really delivers" when connected to non-Chord power amplifiers, describing the result as one of the best preamp performances heard at that level. Its balanced XLR output further broadens compatibility with any amplifier accepting balanced input connections, including designs from Naim, Bryston, Pass Labs, and others.

What is unity gain in the Chord ULTIMA Pre 3?

Unity gain means the ULTIMA Pre 3 has a voltage gain factor of exactly x1: it does not amplify the signal passing through it. The volume control manages the output level by attenuating the signal rather than boosting it, and the active circuitry preserves the source signal at full fidelity without adding gain-related distortion or noise. This design philosophy prioritises signal transparency above all else, which is why the ULTIMA Pre 3 achieves 0.002% THD and -105 dB SNR across all five inputs. Soundnews noted in its in-depth review that unity gain delivers the purest, most unaltered signal from the source, cleaned and revitalised before being sent to the power amplifier stage.

Does the Chord ULTIMA Pre 3 support home cinema integration?

Yes, the Chord ULTIMA Pre 3 includes a dedicated AV bypass input that allows it to integrate into home cinema systems. In AV bypass mode the signal from a surround sound processor is routed through the ULTIMA Pre 3 at unity gain and passed directly to the power amplifier, bypassing the volume control entirely. This means the ULTIMA Pre 3 can serve simultaneously as a reference-class stereo preamplifier for two-channel listening and as the front left and right channel amplification path in a combined stereo and surround system, without compromising the performance of either use case.

What power amplifiers pair best with the Chord ULTIMA Pre 3 in Toronto?

The Chord ULTIMA Pre 3 is engineered to work most synergistically with Chord Electronics' own ULTIMA power amplifiers, including the ULTIMA 5 stereo power amplifier (300W per channel), the ULTIMA 6 stereo power amplifier (180W per channel), and the ULTIMA 2 and ULTIMA 3 monoblock power amplifiers.
