A fantastic power amplifier perfected.

The SP-331MK is an enhancement of the power amplifier SP-331, which upgrades it by higher quality inputs at the rear and dual speaker outputs, which can be switched on and off individually. Featuring an additional vacuum tube over the former model, the SP-331MK perfects the hybrid valve/solid-state amplification method. One of the most popular features of the SP-331MK is the revered "Class A Mode", which offers an exceptional "no compromise" sonic performance.

Class A Mode

The SP-331MK can be operated in Class A mode. Outputting 10W of power per channel in this mode, it has a crystal clear sonic characteristic and completely eliminates harmonic distortions. This mode is enabled by the large storage condenser batteries which provide sufficient power reserves. This allows the Class A circuitry of the unit to provide a faithful deep bass and clean, airy trebles. 

Beyond 10W the amplifier switches to Class AB mode, which offers a lot more power, but is a little less controlled. 

The Best of Two Worlds

The SP-331MK, with its hybrid design, combines the advantages of both vacuum tube and transistor amplification. Valve amplification provides the classic warm tone that audio enthusiasts crave. Combined with transistor solid-state technology, the result is a power amp that is efficient in terms of power consumption, and in sound is timelessly rich. This is a main amplifier with little competition and one that never loses control when working with even the most demanding of loads.

Featured in the SP-331MK are two 6N16 tubes and a large 12AU7 tube for its 'Class A' output. This combines with twelve Toshiba output transistors per channel give this main amplifier all the power and grace you need in your high-end system.

A power amplifier that meets modern AV needs musty be powerful yet delicate. Capable of reproducing everything from airy voice and acoustic instruments to the strength and punch of a huge musical piece. Hear the warm, inviting tones across all dynamic levels.

High Power

The SP-331MK boasts a power delivery of 150 watts per channel at 8 ohms, and a huge 300 watts per channel at 4 ohms. This means that even with the most demanding of Hi-Fi speakers, this power amp can not only handle it, but will bring out your speakers' potential. Whether you're playing dynamic orchestral arrangements, explosive film soundtracks or listening to music on CD or record, the SP-331 is the powerhouse your system deserves.

Minimalistic Design

With its hybrid construction of valves and transistors, the SP-331MK has a lot going on under the hood. However, with your system's visual aesthetic in mind, the exterior of this unit is sleek and minimal.

A stereo preamplifier, such as Vincent's SA-31 or SA-31MK (shown left) is the perfect match for the SP-331MK. Combine this unit with the CD players, tuners and other components from their product range, you can build the most diverse, perfectly harmonious sound system.
