Audiolab 8000P ()
Overview
Built as part of the company’s 8000 series, the 8000P was designed to pair with the Audiolab 8000Q preamplifier, sharing its clean, straight-line aesthetic with matching width and height. Unlike integrated models in the lineup, the 8000P strips away volume controls and front-panel circuitry to focus purely on amplification—offering a dedicated power stage for systems where precision and headroom mattered.
The 8000P sits within a broader family that includes the 8000M mono blocks, 8000T tuner, and 8000DAC, suggesting Audiolab positioned it as a modular component for system builders. While no official documentation outlines its competitive context, forum discussions indicate users considered it alongside the 8000M monos or earlier 8000A models, weighing cost, power, and channel separation.

Key Features
Dual-Mono Power Supply Design
The 8000P adopts separate power supply units for the left and right channels, a design choice aimed at minimizing crosstalk and ensuring stable current delivery under dynamic loads. This dual-mono approach was relatively uncommon at its price point and suggests a focus on channel separation and transient response. The result is a power stage capable of delivering over 40 amps of peak current, giving it authority with difficult speaker loads.
AB Class Amplification with Protection Circuit
Operating in AB class, the amplifier balances efficiency with low idle heat, making it suitable for extended listening sessions. A built-in electronic protection system guards against short circuits, overloads, and thermal runaway—critical for preserving both amplifier and speakers. While the circuit topology isn't detailed in available documentation, the measured THD of no more than 0.05% indicates tight control over harmonic artifacts.
Straight-Line Chassis and RF Intermodulation Mitigation
The 8000P follows Audiolab’s signature “straight line” design language, emphasizing symmetry and minimal front-panel clutter. Internally, sound quality is reportedly improved by eliminating AF/RF intermodulation, a design goal that implies careful shielding and layout to prevent high-frequency interference from degrading audio signals. The chassis, while not described in material terms, houses engineering focused on signal purity rather than cosmetic flair.
Collectibility & Value
Original pricing for the 8000P varied by market, with a Japanese RRP of ¥200,000 and a UK RRP of £600. Current market data is sparse, but a March 2026 listing on Reverb offered an 8000S preamp and 8000P power amp combo for $650. Individual units are occasionally described as "RARE" in listings, and forum users have noted examples as "lightly used," suggesting low attrition among surviving units. No widespread failure modes or maintenance issues are documented, though long-term reliability likely depends on capacitor health and power supply integrity.
