If ever Aristotle’s adage: “the whole is greater than the sum of its parts” is applicable in audio, it applies to AP20. And, given the quality and quantity of parts in this equation, that’s saying a lot. AP20 delivers unprecedented audio performance from an integrated amplifier. It includes the world’s best Class D amp modules in a dual-mono configuration, an analog R2R relay-based volume control and preamp section, Aurender’s best DAC, a master clock input, a headphone output, a suite of digital and analog inputs and outputs, and the most sophisticated linear power supply block Aurender has ever deployed. The result? An audio component that paints every musical timbre with full-bodied realism. With a delicate touch that’s backed up by enormous headroom for transients and dynamic swings, AP20 drives even the most demanding speaker loads and casts a soundstage that is both expansive and laser-focused. All of this performance, with the heart of an Aurender. Other integrated amplifier solutions on the market may offer support for app-controlled streaming, but in nearly every case, the user experience, library management, and software playback engine are an afterthought requiring third-party software and hardware to get the job done. In AP20’s case, more than 10 years of industry-leading experience has made Aurender the digital source component of choice in the world’s finest audio systems. Now, that same holistic digital playback engine and user experience is available from an integrated amplifier that completely removes the need for more components and cables. There’s Class D, and then there’s ridiculously good Class D. AP20 utilizes the finest amplifier modules available. Designed by renowned engineer Bruno Putzeys, the Purifi Eigentakt 1ET400A amplifier is free of digital harshness, edginess, and grain. Featuring impressive specifications that are reflected in its extraordinary audio performance, AP20’s dual-mono amplifier section represents the state-of-the-art of Class D amp technology. In any system, the quality of the audio presentation is significantly impacted by the volume control mechanism of the preamplifier. Remarkably, AP20 employs an analog-domain volume control based on an R2R stepped-attenuator system. Volume control of this quality is utterly uncommon in digitally-equipped integrated amps, and it is a major reason why AP20 provides such a natural, open sound. AP20’s OCXO based precision clock generation system incorporates a Field-Programmable Gate Array (FPGA) with sub 100fs jitter-reducing clock generator to precisely time digital audio data transmissions and minimize jitter to below negligible levels. The AP20 provides a suite of analog inputs including 1X balanced XLR and 2X single-ended RCA, offering an ideal solution for integrating external analog sources into your audio system. Vinyl enthusiasts can connect their phono stage to an available analog input and enjoy pure analog pass-through without any A/D conversion in the signal path. AP20’s high-quality balanced XLR output allows the user to feed subwoofers with line-level input (XLR-to-RCA adapters may be required in some cases). Users are supposed to select the “XLR + Speaker” option in the Aurender app, which enables both XLR and speaker outputs simultaneously to augment bass. Although AP20 is equipped with an extremely precise OCXO clock system, jitter can be minimized further by connecting a 10MHz Master Clock signal generator such as Aurender’s MC10.
Since 2010, Aurender has been an industry leader in digital source components – taking the computer out of “computer audio.”By continually pushing the boundaries of technology in terms of a streamlined user experience and no-compromise audio performance, Aurender’s core goal is simple: to combine exceptional hardware engineering with a software suite that is specifically optimized to take maximum advantage of the hardware at hand. By applying a traditional audiophile component-based design concept to a modern digital solution, Aurender delivers an utterly transparent audio presentation unlike any other.The Aurender ecosystem delivers superior performance, stability, and reliability by maintaining complete control of the hardware and software, requiring no third-party software or external hardware.Aurender’s approach to building a personal music library preserves the experience of actively collecting by aggregating streaming music services with locally stored files on a platform that is not only searchable, but browseable as well.
