Primare SC15 Prisma Preamp: Elevating Your Audio Experience

I. Introduction

The Primare SC15 Prisma Preamp is a noteworthy addition to the 15 series, offering a compact design and advanced features to enhance your audio setup. As a crucial component in any home theater or high-fidelity audio system, a preamp plays a pivotal role in signal processing and routing, ultimately influencing the quality of the audio output. In this review, we'll delve into the design, connectivity, audio performance, and user experience of the Primare SC15 Prisma Preamp to help you make an informed decision for your audio needs.

II. Design and Build Quality

The SC15 Prisma's compact form factor and elegant design make it well-suited for modern living spaces where space is a premium. Constructed with a black aluminum case and a thick cast-metal faceplate available in black and titanium finishes, the preamp exudes a sense of sophistication and sturdiness. The front panel features a small OLED display and intuitive pushbuttons for standby mode and source selection, ensuring ease of use. On the rear panel, the preamp offers an array of connectivity options including analog and digital inputs, USB ports, Ethernet, and Wi-Fi and Bluetooth antennas, catering to diverse audio sources and streaming preferences. The overall aesthetic appeal and user-friendliness of the design make it a seamless addition to any audio setup.

III. Connectivity and Streaming Capabilities

Equipped with Prisma technology, the SC15 Prisma Preamp seamlessly integrates network music player functionality, allowing for effortless streaming from various services and applications. Its support for Apple AirPlay, Chromecast Built-in, Spotify Connect, and DLNA/UPnP ensures compatibility with popular streaming platforms, while the inclusion of Bluetooth, Ethernet, and dual-band Wi-Fi with 802.11ac support offers versatile wireless connectivity options. The future firmware update for wireless audio transmission to WiSA speakers further enhances its flexibility in multi-room setups. Additionally, the USB Type-B connection for improved sound quality from PC or Mac and Chromecast Built-in and AirPlay support for multi-zone playback elevate its streaming capabilities, catering to audiophiles and casual listeners alike.

IV. Audio Performance

The SC15 Prisma Preamp boasts a high-quality DAC chip, the AKM AK4490, supporting up to 32-bit/384kHz PCM and DSD5.6/128, ensuring exceptional digital to analog conversion performance. The inclusion of Class D amplifiers (Hypex UcD) delivering 60 watts per channel, combined with the switching power supply, provides a solid foundation for audio reproduction. Notably, the preamp utilizes Continuous Soundfield Sampling (CSS) to optimize speaker performance based on the room's acoustics, and the room correction process, utilizing the built-in microphone of an Apple iPhone 6S or newer or the dedicated Zen mic (sold separately), further tailors the audio output to the environment. However, it's important to note that the room correction process needs to be redone if speaker placement is changed, which may inconvenience some users.

V. Control and User Experience

The SC15 Prisma Preamp offers convenient control options, including the supplied remote control and the Prisma app, ensuring seamless system control and customization. While the Prisma app provides a user-friendly interface for managing setup menus and music playback, some user feedback highlights the need for further refinement, particularly in the software interface and performance. Occasional glitches reported with music playback and switching between streaming sources also warrant attention for a smoother user experience.

VI. Pros and Cons

The SC15 Prisma Preamp offers a myriad of strengths, including its compact size, versatile connectivity options, support for high-resolution audio formats, and future WiSA support. However, its lack of a phono stage and headphone output, occasional software glitches, and the need for additional refinement in the Prisma app pose as notable limitations. Additionally, the limited power output due to the absence of an internal power amp section may impact its suitability for larger setups.

VII. Final Thoughts

In conclusion, the Primare SC15 Prisma Preamp presents a compelling option for audiophiles seeking a versatile and compact preamp with advanced streaming capabilities. Its high-quality DAC chip, multi-room/multi-zone functionality, and compatibility with popular streaming services make it a valuable addition to any audio setup. However, potential buyers should consider its limitations, including the need for further software refinement and the absence of certain features like a phono stage and headphone output. Overall, the SC15 Prisma Preamp offers a blend of elegance, versatility, and advanced audio features, making it a worthy consideration for those seeking a premium audio experience.

Recommendations for Potential Buyers

If you prioritize compact design, versatile connectivity options, and advanced streaming capabilities in a preamp, the Primare SC15 Prisma Preamp is a compelling choice. However, if you require features such as a phono stage or headphone output, or prioritize a polished software interface, it's advisable to explore alternative options to ensure your audio setup aligns with your specific needs and preferences.
