Hegel P20 Preamplifier at Vinyl Sound Buffalo, NY

The P20 is a stereo preamplifier from Hegel Music Systems (Oslo, Norway), available at Vinyl Sound in Buffalo, NY. Positioned as the entry point into Hegel's Reference line of separates, the P20 employs Silicon Germanium transistors and high-frequency components repurposed from outside the audio domain to achieve a signal-to-noise ratio exceeding 130 dB in balanced mode and distortion below 0.005%. Its chassis is milled from solid aluminum with a bead-blasted, anodized finish, and it ships with the Hegel RC8 remote control — itself machined from a single block of aluminum — providing a tangible sense of high-end quality at every point of contact.

Silicon Germanium Transistors and Reference-Line DNA

The P20's primary technical distinction is its use of Silicon Germanium transistors — a material not traditionally associated with audio preamplifier design. Silicon Germanium offers superior electron mobility compared to standard silicon, enabling Hegel's engineers to achieve exceptionally low noise and distortion figures at signal levels where conventional transistors would introduce audible coloration. This approach, combined with high-frequency components originally developed for other engineering disciplines, allows the P20 to deliver a noise floor typically reserved for far more expensive preamplifiers. The result is a soundstage described by Hegel as enormous, with deep and rhythmic bass response and the kind of precise timing that communicates the rhythmic momentum of a live performance. Many of the ideas and design principles used here were inherited from higher-level Hegel preamplifiers, scaled to meet a more accessible price point without sacrificing sonic character.

Connectivity and System Integration

Despite its entry-level positioning, the P20 provides a comprehensive input and output roster. Five line-level inputs include one balanced XLR and four unbalanced RCA connections, plus a dedicated Home Theatre input that allows seamless integration with surround sound processors — fixing the gain at a high line level so the AV receiver or processor handles volume for the front channels. Outputs cover both balanced XLR and unbalanced RCA for main system connections, plus a fixed-level RCA recording output for use with recording devices or secondary zones. The RC8 remote, included in the box, provides volume, source selection, and mute control and doubles as a computer playback controller when connected to a Hegel DAC or amplifier via USB or network.

Key Features

• Silicon Germanium Transistors: A technology borrowed from outside traditional audio design, providing ultra-low noise and distortion performance well beyond what conventional silicon transistors achieve at this price point.
• 130 dB Signal-to-Noise Ratio (Balanced): One of the highest SNR figures in its class, ensuring a completely silent background and maximum preservation of low-level musical detail.
• Five Inputs Including Balanced XLR: One XLR balanced input, four RCA unbalanced inputs, and a Home Theatre input cover virtually every source topology in a high-fidelity two-channel or hybrid system.
• Balanced and Unbalanced Outputs: XLR balanced and RCA unbalanced main outputs, plus a fixed-level RCA recording output, offer flexible integration with power amplifiers and recording devices.
• Home Theatre Bypass Input: A dedicated HT input fixes the gain at a high line level, allowing direct integration with AV surround processors for seamless two-channel and home cinema use.
• Hegel RC8 Remote Control Included: Machined from a single block of aluminum with the same bead-blasted, anodized finish as the P20 itself — volume, source, and mute control plus computer playback functions.
• Precision Aluminum Chassis: 8 x 43 x 30 cm enclosure with a bead-blasted, anodized aluminum front panel and knobs, available in black.

Frequently Asked Questions

What is the Hegel P20?

The Hegel P20 is a stereo preamplifier from Hegel Music Systems of Oslo, Norway, designed as the entry point into the brand's Reference line of separate components. It uses Silicon Germanium transistors to achieve a signal-to-noise ratio exceeding 130 dB in balanced mode and distortion below 0.005%, offering a level of sonic performance uncommon at its price point in a five-input chassis that ships with the all-aluminum RC8 remote.

How does the Hegel P20 compare to the Cambridge Audio CXA81?

The Hegel P20 is a dedicated preamplifier intended to partner with a separate power amplifier, whereas the Cambridge Audio CXA81 is an integrated amplifier that combines preamplifier and power amplifier stages in one chassis. The P20's signal-to-noise ratio exceeds 130 dB in balanced mode, a figure considerably higher than what integrated amplifiers at that level typically achieve, and its Silicon Germanium transistor input stage targets lower noise and distortion. Listeners building a separates system who want a transparent, low-coloration preamplifier with balanced I/O and Home Theatre integration will find the P20 a more purposeful choice, while those seeking an all-in-one solution would look to a Hegel integrated such as the H95 or H150.

Can the Hegel P20 be used in a home theatre setup?

Yes, the P20 includes a dedicated Home Theatre input that fixes the gain at a high, constant line level. This allows an AV processor or surround receiver to take over volume control for the front left and right channels, making the P20 a transparent pass-through within a hybrid two-channel and home cinema system without any additional configuration.

What is the Silicon Germanium transistor technology in the P20?

Silicon Germanium is a semiconductor material that offers higher electron mobility than standard silicon, enabling transistors to operate with lower noise and faster switching at audio frequencies. Hegel used Silicon Germanium transistors in the P20 to push the noise floor well below what conventional audio transistors can achieve, along with high-frequency components originally designed outside the audio industry — an approach that results in the P20's exceptionally high signal-to-noise ratio and low distortion figures.

Does the Hegel P20 come with a remote control?

Yes, the P20 includes the Hegel RC8 remote control as standard. The RC8 is machined from a single block of anodized aluminum, matching the finish of the P20 itself, and provides volume, source selection, and mute control. It also functions as a computer playback controller when a Hegel DAC or amplifier is connected via USB or network.

What power amplifier pairs well with the Hegel P20?

The P20 is designed to partner naturally with Hegel's own power amplifiers such as the H20 or H30A, sharing the same Norwegian design philosophy and balanced XLR connectivity, but its standard XLR and RCA outputs make it compatible with any quality power amplifier. The balanced output with its 130 dB-plus SNR is particularly suited to low-noise power amplifiers where the preamplifier's dynamic range would otherwise be the limiting factor.

Where can I buy the Hegel P20 in Buffalo, NY or the USA?

The Hegel P20 is available at Vinyl Sound in Buffalo, NY — an authorized Hegel dealer serving audiophiles across Western New York and the United States. The team at Vinyl Sound can demonstrate the P20 in a full Hegel separates context alongside compatible power amplifiers and source components.
