SP33 AV preamp

Skip to content

Product Overview

The SP33 is a finely engineered, easy-to-use audio and video processor, complete with excellent system expansion flexibility and the promise of astonishing sound and picture resolution for years to come. Match the SP33 with the Primare A30.7 UFPD power amplifier for the ultimate statement of home entertainment luxury from Primare.

With a comprehensive array of digital and analogue connections: low-noise balanced audio inputs and outputs, HDMI inputs and outputs, a Zone 2 output for performance in a second room, and IR and RS232 connections for the highest possible automation flexibility, the SP33 will integrate easily with any high quality installation. It gives you the opportunity for powerful custom configuration in your home environment, allowing you to personalise operation and to optimise the performance of your system. 

Almost every parameter can be user defined using new onscreen menus and the C24 remote supplied. Assign a name to any input and associate it with any audio and video source. Surround format, trigger activation and input sensitivity may be specified for each input, and surround formats – including Dolby TrueHD or DTS-HD Master Audio – custom-set for level, speaker type, crossover frequency, delay and bass configuration. In addition, a 250mS global delay system with dedicated DSP is incorporated in order to achieve the best possible picture-to-sound synchronisation. The SP33’s new 4KVM video circuitry features 4K and 3D video pass-through, with matrix switching for six HDMI inputs and two ARC assignable HDMI outputs for perfect performance from a choice of two displays.

Note: the 4KVM video module was developed primarily to partner our upscaling to 4K universal disc player BD32 MKII. The 4KVM design was initiated before the release of HDMI 2.0a specifications. Those specifications demand a higher clock speed necessary for HDR switching than the chip in the 4KVM is able to provide. As a result, 4KVM will work with most, if not all, sources that allow for turning HDR off and with only minor limitations on playback specifications as seen below:

– 24Hz 4:4:4 4096 x 2160 DCI
– 24/25/30Hz 4:4:4 3840 x 2160 4K UHD
– 50/60Hz 4:2:0 3840 x 2160 4K UHD

    SP33: Germany’s online AV mag i-fidelity loves the SP33/A30.7 system

    Germany’s online AV mag i-fidelity loves the SP33/A30.7 system. Marking the system as ‘superb’ for sound quality and ‘very good’ in almost every other category reviewer Raphael Vogt says: “With the SP33 and A30.7 duo Primare offers a surround pre/power amp combo with an almost classical appearance; a perfect, massive workmanship and a pleasantly purist no-frills design. Here the sound and build quality are absolutely brought into focus… Sound wise the combo presents a muscular body and a steady imaging that is virtually palpable and intimately close at the highest level.”
