Primare SPA25 Prisma Home Cinema Integrated Amplifier at Vinyl Sound Buffalo, NY USA

The SPA25 Prisma is a multi-channel home cinema integrated amplifier and processor from Primare (Malmö, Sweden), available at Vinyl Sound in Buffalo, NY, USA. Combining 9 channels of Hypex Class D amplification with 11-channel Dolby Atmos and DTS:X processing, built-in Dirac Live room correction, dual ESS ES9026PRO 8-channel DACs, eARC HDMI, and the full Prisma network streaming platform, the SPA25 Prisma is the most powerful and versatile home cinema integrated amplifier Primare has ever produced. Awarded EISA Best AV Receiver 2023-2024, it delivers 145W per channel into 8Ω, rising to 290W per channel when bi-amping the main stereo pair.

9-Channel Hypex Class D Amplification and Dual ESS DAC Architecture

The SPA25 Prisma houses nine channels of energy-efficient Hypex Class D amplification driven by an adaptive power supply that delivers power on demand. Each channel produces 90W into 8Ω continuously, with the adaptive supply enabling 145W into 8Ω and 250W into 4Ω when pushed. Bi-amping the Front Left and Right channels unlocks 290W into 8Ω per speaker. At the heart of the conversion stage sit dual ESS ES9026PRO 8-channel DAC chips, configured so that four conversion channels are dedicated exclusively to the front left and right outputs — a circuit topology that delivers significantly improved stereo performance compared to a standard multi-channel allocation. The USB-B input enables high-resolution USB DAC functionality for two-channel listening.

Dirac Live Room Correction and System Configuration Flexibility

Dirac Live is built in as standard, correcting not only frequency response but also phase and arrival time simultaneously — expanding the listening sweet spot, tightening bass, improving voice intelligibility, and sharpening stereo imaging in both two-channel and multi-channel modes. Seventeen customisable input presets and five speaker setup presets accommodate virtually any combination of digital, analog, and video inputs across any room layout. Front L, Front R, and Centre RCA outputs allow seamless integration of external power amplifiers for those channels, and with the addition of a stereo power amplifier, configurations up to 7.1.4 are achievable.

Prisma Network Streaming Platform

The integrated Prisma network player provides access to major streaming services including Tidal HiFi, Qobuz, and Spotify Connect (HiFi Ready), alongside multi-room and multi-zone control managed from the Prisma app. AirPlay 2, Bluetooth, and Chromecast built-in are supported natively. Prisma Radio is embedded for direct radio access, and network-connected hard drives are fully supported for local library playback. Roon Ready certification is available via a future firmware update. The SPA25 Prisma is the first Primare model to include the new PRISMA Universal IR Remote — backlit, compatible with every current and past Primare model, and supporting OTA firmware updates.

Frequently Asked Questions

What is the Primare SPA25 Prisma?

The Primare SPA25 Prisma is a 9-channel home cinema integrated amplifier and processor from Primare (Sweden) with 145W per channel into 8Ω, 11-channel Dolby Atmos and DTS:X processing, Dirac Live room correction, dual ESS ES9026PRO DACs, 4 HDMI 2.0b inputs with eARC, and the Prisma network streaming platform. Unlike a traditional AV receiver, it uses Hypex Class D amplification and a dedicated DAC allocation for the stereo front channels, reflecting its audiophile design heritage.

How does the Primare SPA25 Prisma compare to the Arcam AVR31?

The Primare SPA25 Prisma and Arcam AVR31 are both premium multi-channel integrated amplifiers, but they differ in power, amplifier topology, and streaming integration. The SPA25 Prisma uses Hypex Class D amplification at 145W per channel, while the AVR31 uses Class G at 120W per channel. Both units use Dirac Live for room correction and support 11-channel Atmos and DTS:X. The SPA25 Prisma adds the Prisma multi-room streaming platform with AirPlay 2, Chromecast built-in, and Spotify Connect natively, and its bi-amp mode delivers up to 290W into 8Ω per speaker on the front pair — a significant power advantage for larger rooms and harder-to-drive speakers.

How does the Primare SPA25 Prisma compare to the Denon AVC-X6700H?

The Primare SPA25 Prisma and Denon AVC-X6700H both target the upper-tier home cinema amplifier segment with 11-channel processing and built-in streaming. The AVC-X6700H uses conventional linear amplification at 140W per channel and Audyssey MultEQ XT32 room correction. The SPA25 Prisma counters with Hypex Class D amplification, Dirac Live (which corrects phase and time-domain as well as frequency), and the dedicated four-channel DAC allocation for the front stereo pair. The SPA25 Prisma's Prisma streaming platform also offers multiroom functionality and higher-resolution streaming capabilities beyond what Denon's HEOS platform provides.

What is Hypex Class D amplification?

Hypex Class D is a high-efficiency switching amplifier topology developed by Hypex Electronics (Netherlands) and used in audiophile-grade equipment for its combination of low distortion, high power output, and low heat generation. Unlike conventional Class A or Class AB designs, Class D switches the output transistors at very high frequency, recovering energy that would otherwise be lost as heat. In the SPA25 Prisma, the adaptive Hypex power supply delivers current on demand rather than continuously, allowing the amplifier to achieve high peak outputs while remaining energy-efficient during normal listening levels.

Can the Primare SPA25 Prisma power a 7.1.4 Atmos system on its own?

The SPA25 Prisma's 9 built-in amplification channels support configurations including 5.1.4 and 7.1.2 natively, and 5.1.2 with bi-amped front speakers. A full 7.1.4 configuration requires the addition of a stereo power amplifier for the front left and right channels, freeing the internal amplifier channels to cover all seven surround and height positions. The Front L and Front R RCA outputs on the back panel are provided specifically for this purpose.

Does the Primare SPA25 Prisma support Roon?

Roon Ready certification for the SPA25 Prisma is available via a future firmware update. Tidal HiFi and Qobuz direct streaming are also being added via firmware. The unit natively supports AirPlay 2, Chromecast built-in, Bluetooth, and Spotify Connect from day one, allowing Roon users to stream via AirPlay 2 in the interim.
