Aurender AP20 Reference All-in-One Music Server, DAC & Integrated Amplifier

The Aurender AP20 combines a high-end music server and streamer, dual-mono DAC, analog preamplifier and 200-watt-per-channel integrated amplifier in one reference component. Its dual-mono Purifi Eigentakt amplification delivers 200W per channel into 8 ohms and 350W per channel into 4 ohms, backed by a full linear power supply using six toroidal transformers.

The AP20 also incorporates a dual-mono AKM AK4497 DAC, relay-based R2R analog volume control, OCXO precision clock, 10MHz master-clock input, balanced analog connectivity, headphone output and two user-installable music-storage bays. It is designed as a complete high-end system: add loudspeakers and a network connection. Aurender Music

200W Dual-Mono Purifi Eigentakt Amplification

The AP20 uses two Purifi 1ET400A Class D amplifier modules designed by Bruno Putzeys and implemented in a dual-mono configuration.

Rated output is:

• 200W per channel into 8Ω
• 350W per channel into 4Ω
• 0.003% THD from 20Hz–20kHz
• 800 damping factor
• <65μΩ output impedance at 1kHz

Speaker outputs use WBT nextgen pure-copper terminals. Aurender Music

Six-Toroidal Full Linear Power Supply

Rather than pairing its Class D output stages with conventional switch-mode supplies, Aurender built the AP20 around a fully linear power architecture with six discrete toroidal transformers.

Two 400VA transformers supply the left and right power-amplifier channels. Separate transformers supply the left and right audio boards, CPU and FPGA circuitry. Power-amplifier filtering totals 80,000µF—40,000µF per channel. Aurender Music

A supercapacitor-based internal UPS provides controlled shutdown protection during unexpected power loss.

Dual-Mono AKM AK4497 DAC

Digital conversion uses dual AKM AK4497 DACs in a dual-mono configuration.

The AP20 supports analog-output playback up to:

PCM: 32-bit / 768kHz
DSD: Native DSD512

The AP20 also includes onboard MQA full decoding. Aurender Music

Relay-Based R2R Analog Volume Control

Volume is controlled in the analog domain using a precision relay-based R2R resistor-ladder attenuator rather than relying on conventional digital attenuation.

Volume can be controlled from the front-panel rotary control, Aurender Conductor app or supplied IR remote. Aurender Music

OCXO Precision Clock & 10MHz Master Clock Input

The AP20 uses an OCXO-based precision clock system with FPGA processing and a sub-100-femtosecond jitter-reducing clock generator.

A dedicated rear-panel master-clock input also allows the AP20 to reference an external 10MHz clock such as the Aurender MC10 or MC20. Aurender Music

Analog Inputs with Pure Analog Pass-Through

External analog sources can be connected through:

1 × balanced XLR input
2 × stereo RCA inputs

The analog inputs use a pure analog pass-through path without analog-to-digital conversion, making the AP20 suitable for external phono stages and other premium analog sources. Aurender Music

Digital Inputs

External digital sources can use the AP20's internal DAC through:

• 1 × RCA coaxial S/PDIF
• 1 × BNC coaxial S/PDIF
• 2 × optical/Toslink

The digital inputs support signals up to 24-bit/192kHz. Aurender

Balanced XLR Auxiliary Output

A balanced XLR analog output can operate alongside the speaker outputs.

Selecting Speaker + XLR enables both simultaneously, allowing the balanced output to feed compatible powered subwoofers or other line-level equipment while the AP20 continues driving the main loudspeakers. Aurender Music

Dedicated Headphone Output

A front-panel 1/4-inch / 6.35mm headphone output provides dedicated headphone listening without requiring a separate headphone amplifier. Front-panel output selection switches between Speaker, Headphone and Speaker + XLR operation. Aurender

Aurender Music Server & Streaming Platform

The AP20 incorporates Aurender's complete music-server architecture rather than adding a third-party streaming module to an integrated amplifier.

It includes:

• Intel low-power quad-core processor
• 8GB RAM
• 480GB NVMe system and cache SSD
• Double-isolated Gigabit Ethernet
• Aurender caching playback engine
• Aurender Conductor software
• USB storage/NAS support
• Integrated streaming services
• Critical Listening Mode
• Supercapacitor UPS Aurender Music

Aurender's integrated services include TIDAL, Qobuz, Internet Radio, Spotify Connect and AirPlay. Aurender Music

Dual User-Installable Music Storage

Two accessible 2.5-inch HDD/SSD bays allow local music storage to be installed according to the size of the user's library.

Playback occurs from the AP20's solid-state cache rather than directly from the storage drive, separating music-library storage from active playback operations. Aurender Music

8.8-Inch Color Display

The machined-aluminum front panel incorporates an 8.8-inch 1920 × 480 IPS color display for album artwork, track information, playlists and system information. Aurender Music

Aurender AP20 Technical Specifications

Aurender's current product page lists the AP20 chassis at 16.93"W × 14.2"D × 5.9"H and 57.3 lb. However, Aurender's January 2026 hardware guide gives 16.93"W × 15.0"D × 6.3"H and 59.5 lb. Because the manufacturer's own current documents conflict, I would use the current product-page dimensions in Shopify and avoid mixing the two sets. Aurender Music

Aurender AP20 at The Grid HiFi

The Aurender AP20 eliminates multiple components without reducing the system to a conventional streaming amplifier. Music server, streamer, reference DAC, analog preamplifier and 350W-per-channel 4-ohm amplification are engineered within one chassis.

That makes the AP20 particularly compelling for a reference two-channel system where the goal is fewer components and cables without stepping down from serious high-end electronics.

The Grid HiFi can match the AP20 with appropriate loudspeakers, network architecture, internal SSD storage and external Aurender MC10 or MC20 master clock where applicable.

Order the Aurender AP20 from The Grid HiFi or call (713) 218-8120 for system matching and configuration.
