Aurender A20 vs AP20: Two Ways to Build a High-End Streaming System
High-end streaming systems no longer need to be built around a general-purpose computer.
Aurender's approach is to make the digital source a dedicated audio component, combining purpose-built hardware with the company's Conductor control software. The A20 and AP20 take that philosophy in two different directions.
The A20 is a network music server with analogue outputs, DAC and headphone section. The AP20 goes much further by adding a preamplifier and high-power integrated amplifier.
What the Aurender A20 Does
Aurender currently identifies the A20 as a Signature Analog Music Server.
The manufacturer specifies a dual-mono AKM4497 DAC architecture, balanced XLR and single-ended RCA analogue outputs, a dedicated USB audio output and coaxial/optical digital inputs.
The A20 also provides two user-installable 2.5-inch storage bays, allowing the owner to add HDD or SSD storage for a local music library.
Aurender specifies support for PCM up to 32-bit/768 kHz and DSD512 through the analogue-output DAC path. It uses an OCXO audio word clock, an 8.8-inch IPS front display and a double-isolated Gigabit LAN connection.
The practical attraction is consolidation: streamer, music library, DAC, variable output and headphone listening in one chassis.
What the AP20 Adds
The AP20 is an all-in-one music server and integrated amplifier.
Aurender specifies two Purifi 1ET400A Class D amplifier modules in dual-mono configuration, rated at 200 watts into 8 ohms and 350 watts into 4 ohms.
The AP20 also uses a dual-mono AKM4497 DAC, but adds an analogue relay-based R2R stepped attenuator for volume control, analogue inputs, speaker outputs and a balanced XLR auxiliary output.
Aurender states that the analogue inputs pass through without A/D conversion, which is particularly relevant for vinyl listeners connecting an external phono stage.
A20: Best When You Already Own Amplification
The A20 makes the most sense when the existing amplifier or pre/power combination is already a deliberate part of the system.
Its variable analogue outputs allow it to feed a preamplifier or, in suitable systems, operate with volume control into downstream amplification. The USB audio output also means the A20 can serve as a digital source for an external DAC if the system evolves later.
That makes it a flexible foundation for someone who wants Aurender's server and library ecosystem without replacing the amplifier.
AP20: Best When You Want Fewer Boxes
The AP20 is aimed at the listener who wants a much more integrated architecture.
Because the network player, storage platform, DAC, volume control and power amplifier are in one chassis, a complete system can be reduced to AP20 plus loudspeakers - with optional external analogue sources.
The amplifier specification is substantial enough to suit a much wider range of speakers than a low-powered integrated. Aurender's 200 W/8-ohm and 350 W/4-ohm ratings also make the AP20 a logical candidate for speakers that require meaningful power reserves.
Storage and Library Playback
Both products include two user-installable 2.5-inch storage compartments and a 480 GB NVMe SSD for system/cache duties according to Aurender's specifications.
Aurender's architecture uses caching playback: music is played from solid-state cache memory rather than continuously read from the original storage location during playback.
Both units also support external USB storage and NAS connectivity, while Aurender promotes internal storage as the preferred user experience.
Streaming Services and Control
Aurender integrates services including TIDAL, Qobuz and Internet Radio through its Conductor ecosystem, with Spotify Connect and AirPlay also listed by the manufacturer.
The point of a dedicated server is not only audio hardware. It is the integration of library management, streaming and control into a single platform.
For a high-end system, reliability and ease of use matter because a digital source that is frustrating to navigate will simply be used less often.
Connectivity Differences
The A20 provides both balanced XLR and single-ended RCA analogue outputs.
The AP20's main auxiliary analogue output is balanced XLR, and its analogue input set includes one balanced XLR input and two single-ended RCA inputs. Digital inputs include coaxial RCA, coaxial BNC and two optical/Toslink connections.
Aurender also equips the AP20 with a 10 MHz master-clock input.
FAQs
Does the Aurender A20 need an external DAC?
No. It includes a dual-mono AKM4497 DAC, although it also provides a dedicated USB digital output for an external DAC.
How much power does the AP20 produce?
Aurender rates it at 200 W into 8 ohms and 350 W into 4 ohms.
Can the AP20 accept a phono stage?
Yes. Aurender provides analogue inputs and states that analogue pass-through occurs without A/D conversion.
Can both models store music internally?
Yes. Both provide two user-installable 2.5-inch storage bays.
Conclusion
The A20 and AP20 are not simply two versions of the same streamer.
Choose the A20 when you want a serious digital source and DAC while retaining existing amplification. Choose the AP20 when you want Aurender's streaming platform, DAC, preamplification and 200-watt-per-channel amplification consolidated into one component.
Both show how a modern high-end streaming system can become easier to operate without treating the source as an afterthought.
