Audiolab 9000P Stereo / Monoblock Power Amplifier at Vinyl Sound Toronto Canada

The 9000P is the flagship dedicated power amplifier from Audiolab (Cambridge, United Kingdom), available at Vinyl Sound in Toronto, Canada. Designed as the natural power amplification partner for the 9000Q preamplifier — and Audiolab's first standalone power amplifier in eight years — the 9000P delivers a genuine 100W per channel into 8 ohms (160W into 4 ohms) in stereo mode, or 300W into 8 ohms (380W into 4 ohms) in bridged monoblock configuration. Built around Audiolab's signature CFB (Complementary Feedback) Class AB topology, a maximum output current of 15A, and both balanced XLR and unbalanced RCA inputs, the 9000P offers a versatile, high-headroom amplification platform suited to demanding loudspeakers, high-current applications, and biamplified system architectures. It matches the 9000A's 100W output rating exactly, making it the precision power complement to the 9000Q in a full separates system.

CFB Class AB Power Stage and Dual Operating Modes

The 9000P's discrete Class AB power stage uses Audiolab's CFB (Complementary Feedback) topology — the same circuit architecture deployed in the 9000A and 7000A integrated amplifiers — ensuring superior linearity and exceptional thermal stability by maintaining idle current independently of output transistor temperature. The result is consistent, low-distortion performance across all listening levels and operating temperatures, with THD measuring below 0.002% at 1kHz throughout the power range. Maximum output current of 15A — matching the 9000A — provides ample headroom for driving low-impedance and reactive loudspeaker loads. The bridged monoblock mode converts the 9000P from a stereo amplifier into a single-channel monoblock delivering 300W into 8 ohms and 380W into 4 ohms, following the success of Audiolab's acclaimed 8300MB monoblock power amplifier. This makes a pair of 9000P units a compelling choice for listeners who require substantially higher power — 600W total into 8 ohms — for large room installations or power-hungry loudspeakers such as those from Wharfedale, Klipsch, or KEF.

Flexible Connectivity and System Integration

The 9000P accepts both unbalanced RCA and balanced XLR analogue inputs, with separate gain settings — 29dB via RCA and 23dB via XLR — allowing precise level matching to any preamplifier or integrated amplifier's preamp output. Input impedance of 10k ohms is compatible with all standard preamplifier output stages. A 12V trigger input enables automated power sequencing from the 9000Q preamplifier's trigger output, so the entire 9000 series system powers on and off as a single unit without manual intervention. The 9000P can be used in three distinct system roles: as a dedicated stereo power amplifier partnered with the 9000Q, as an add-on power amplifier connected to the 9000A's preamp output in Pre-Power mode for a full separates upgrade, or in bridged mono configuration — deploying a single 9000P per channel — for reference-level monoblock performance. The chassis dimensions and finish match the 9000Q and other 9000 series components precisely, maintaining the visual coherence of a stacked system.

Key Features

• 100W Per Channel into 8 Ohms, 160W into 4 Ohms (Stereo): Discrete Class AB power stage with CFB topology and 15A maximum output current, matching the 9000A's rated output for like-for-like system pairing with the 9000Q.
• 300W into 8 Ohms, 380W into 4 Ohms (Bridged Mono): Built-in bridged monoblock mode converts the 9000P into a single-channel power amplifier for high-power applications, large rooms, or biamplified loudspeaker systems.
• CFB (Complementary Feedback) Topology: Audiolab's proven Class AB circuit architecture maintains idle current independently of output transistor temperature for superior linearity, thermal stability, and consistent low-distortion performance.
• 15A Maximum Output Current: Matches the 9000A and provides ample current delivery for driving low-impedance and reactive loudspeaker loads without clipping or compression at high listening levels.
• Balanced XLR and Unbalanced RCA Inputs: Accepts both single-ended and balanced signals from any preamplifier, with separate gain figures (29dB RCA, 23dB XLR) for precise level matching.
• THD below 0.002% at 1kHz: Vanishingly low distortion throughout the power range, consistent with the 9000 series' reference-level performance specification.
• SNR above 112dB (A-weighted): A very low noise floor that preserves the full resolution of upstream DAC and streaming sources including the 9000N and 9000Q.
• 12V Trigger Input: Enables automated power sequencing from the 9000Q preamplifier's trigger output for seamless one-touch system operation.
• Three System Roles: Stereo power amplifier with 9000Q, add-on power amplifier via the 9000A's preamp output, or bridged monoblock for high-power mono duty — one chassis covers all configurations.
• Matched 9000 Series Aesthetics: Identical chassis width and height to the 9000Q and 9000A for a visually aligned stacked system in black or silver finish.
• Frequency Response 20Hz to 20kHz (+/- 0.3dB): Full audible bandwidth performance with consistent output across the entire frequency range.

Frequently Asked Questions

What is the Audiolab 9000P?

The Audiolab 9000P is the flagship dedicated power amplifier from Audiolab (Cambridge, UK), delivering 100W per channel into 8 ohms and 160W per channel into 4 ohms in stereo mode, or 300W into 8 ohms in bridged monoblock configuration. It uses a discrete Class AB power stage with CFB (Complementary Feedback) topology, accepts both RCA and XLR inputs, and includes a 12V trigger input for automated system power sequencing.

How does the Audiolab 9000P compare to the Audiolab 9000A?

The 9000A is a full integrated amplifier combining preamplifier, DAC, phono stage, headphone amplifier, and 100W power stage in one chassis. The 9000P is a dedicated power amplifier only — no DAC, no preamp section, no phono stage — designed to be driven by a separate preamplifier such as the 9000Q. Both deliver the same 100W per channel into 8 ohms via the same CFB Class AB topology and 15A maximum output current. The key advantages of the 9000P are bridged monoblock capability (300W mono) and the potential for higher performance through dedicated component specialization when paired with the 9000Q.

What is bridged monoblock mode and when should I use it?

In bridged mono mode, both channels of the 9000P are combined to drive a single loudspeaker, effectively doubling the available voltage swing. The 9000P delivers 300W into 8 ohms and 380W into 4 ohms in this configuration — three times the stereo per-channel output. A pair of 9000P units in bridged mono mode provides 600W total into 8 ohms for large room installations, very inefficient loudspeakers, or systems where maximum headroom and dynamic range are priorities. Each bridged 9000P drives one channel, so two units are required for stereo monoblock operation.

Can the Audiolab 9000P be used with the Audiolab 9000A?

Yes. The 9000A's Pre-Power mode disconnects its internal power stage and routes the signal to its PRE Amplifier Out socket. Connecting that output to the 9000P's RCA or XLR input creates a pre/power system using the 9000A's preamplifier, DAC, phono stage, and headphone amplifier alongside the 9000P's dedicated power stage. This is a practical upgrade path for existing 9000A owners who want higher power or the option of bridged mono operation without replacing the entire amplifier.

What loudspeakers work best with the Audiolab 9000P?

In stereo mode at 100W per channel into 8 ohms, the 9000P drives the vast majority of floorstanding and standmount loudspeakers with authority. Its 15A maximum output current makes it particularly well suited to low-impedance and reactive designs. In bridged mono mode at 300W into 8 ohms, it becomes a practical choice for large room applications, very low-sensitivity loudspeakers, or high-power designs from manufacturers such as Wharfedale, KEF, Bowers and Wilkins, or Klipsch that benefit from substantial current and headroom reserves.

How does the Audiolab 9000P compare to the Parasound A21+?

The Parasound A21+ delivers 300W per channel into 8 ohms in stereo from a single chassis, using a high-bias Class A/AB design with a heavier power supply. The Audiolab 9000P delivers 100W per channel stereo or 300W mono from a more compact and lighter chassis, relying on CFB topology for linearity and thermal stability rather than high idle current. The A21+ is the stronger choice for listeners who need sustained high-power stereo output from one unit; the 9000P is better suited to those who prioritize system integration within the 9000 series or who want bridged mono capability with the option to expand to two units.
