The advantages of storing and utilizing a music library as audio files rather than on optical discs are widely recognized, making further persuasion unnecessary. A significant development supporting this shift has been the introduction of files encoded in the original DSD format, along with compatible playback devices, which have rendered high-resolution SACD discs largely obsolete. While these players were once considered costly, they are now becoming more common in affordable packages and mini-systems, often replacing traditional optical disc players.
A notable example of this system is the Pioneer P2-K. Similar to its counterpart, the P1-K, it features a pair of two-way speakers along with two separate units: a source and a stereo receiver. However, instead of a traditional CD player, this model incorporates a network file player that supports high-resolution streaming audio, among other capabilities. The receiver and speakers in both systems are identical.
The front panels of both the receiver and player are crafted from anodized aluminum, giving them a robust appearance. A significant portion of the player’s front panel, approximately one-third, is dedicated to a 3.5-inch color LCD display. This display provides information about the currently playing file, album artwork, and a list of files and folders. However, the display can only show four lines at a time, which may hinder navigation through extensive collections, requiring users to scroll through the list multiple times to find a specific artist or album. For a compact component, this limitation is understandable, and it is often more practical to use a smartphone or tablet for navigation, which will be discussed further.
The front panel features a color display along with standard playback control buttons and a USB port. On the rear panel, you will find an analog output via RCA connectors, a digital optical output, and an Ethernet RJ-45 port. However, it lacks a USB type B port for direct computer connection, meaning it cannot function as a high-end DAC like the Pioneer N-50 model. Nevertheless, it is designed for different purposes and offers a wide range of capabilities.
In contrast to the Pioneer N-50, this player can connect to a local network through a DLNA server using Wi-Fi, supported by two antenna connectors located on the back panel. This greatly enhances installation flexibility, as there is no need to run a twisted pair cable or invest in additional Wi-Fi adapters. The data transfer rate, utilizing the 802.11n standard, is sufficient to stream even the largest files seamlessly. The player supports various formats, including DSD, AIFF, Apple Lossless, FLAC, and WAV, with specifications up to 192 kHz/24 bit, in addition to standard formats like MP3, WMA, and AAC. It can play these formats both over the network and directly from external drives and USB flash drives, with the exception of DSD files, which can only be played from external USB drives.
The system allows users to play files directly from Apple mobile devices, such as iPhones and iPads, when connected via USB or AirPlay. Additionally, it supports playback from any device using Bluetooth with aptX protocol, ensuring optimal audio quality for this interface.
As previously noted, playback and navigation through the music library can be managed via the front panel display; however, this method may not be the most user-friendly. A more efficient approach is to utilize a smartphone or tablet running either Android or iOS, provided that a free application is installed beforehand. While older models faced some challenges in this regard, recent firmware updates have significantly improved functionality. The display provides ample information, allowing users to locate their desired albums more quickly.
The system performs exceptionally well with this source. Additionally, to enhance the overall experience, consider experimenting with the connection between the player and the receiver. The receiver is equipped with both analog inputs and two digital options: optical and coaxial, allowing it to function as an external DAC for the player.
The compact Pioneer SX-P01 receiver features proprietary Class D3 amplification modules, which are also found in the company’s higher-end AV receivers. This design ensures high efficiency, delivering dynamic and powerful sound while consuming only 48 W from the power supply, as stated by the manufacturer. The digital-to-analog conversion is managed by AK4588VQ chips from Asahi Kasei Microsystems, which support a digital stream of 24 bit / 192 kHz. The device’s switching panel includes two pairs of screw-type acoustic terminals, and there is an option to enhance the system’s bass response by connecting an active subwoofer.
The included universal remote allows for control over both the player and the receiver. When the volume is kept at a reasonable level, the Pioneer P2-K delivers a comfortable and detailed audio experience. The system produces a clean and accurate soundstage, with precise placement of sound sources. Although the absence of a subwoofer means the bass lacks overwhelming power, it remains well-defined and responsive. The two components are well-matched, with the amplifier setting achievable expectations for the speakers and clearly delineating their operational range. Additionally, the versatility of the Pioneer P2-K is noteworthy, as it performs admirably across various musical genres.
