The Vincent SV-237MK integrated amplifier is not too different from the previous version. For example, user requests were taken into account, and instead of USB, coaxial and optical connectors were installed, through which you can transfer files in quality up to 24 bit/192 kHz, and a headphone output appeared on the front panel. According to the developers, there is nothing else to change in this amplifier: “It’s difficult to make something better that is already excellent in its price category.” The preamplifier section uses two 6N1P tubes, and the relays and potentiometers inherited from its predecessor provide a good signal-to-noise ratio.

The integrated circuit produces 250 W per channel into 4 ohms, 150 W per channel into 8 ohms, and when operating in pure class A it is capable of delivering 10 watts into 8 ohms. Among the inputs, in addition to optical and coaxial, the device is equipped with four RCA, on the rear panel there are outputs for a preamplifier, a recorder, two 3.5 mm trigger jacks and four pairs of acoustic terminals.

Getting to know the inner world of the Vincent SV-237MK can bring true pleasure to an audio enthusiast. True, for this you will have to work a little with a screwdriver, freeing the top cover from many screws. In the center, a little closer to the rear wall of the case, there is a huge toroidal power transformer For Audio Low Noise, capable of delivering up to 5 kW of energy at its peak. To reduce interference to the signal blocks of the amplifier, it is covered with a solid steel screen. Actually, it is this transformer that is the most massive structural element, which must be taken into account when carrying the amplifier – its center of gravity is shifted to the rear.

The interior space is divided into compartments by continuous steel screens. Each functional block has its own compartment. PCB mounting is clean and tidy. Pre-amplification is concentrated directly behind the front panel. Power amplifiers are located along the side walls. Each channel is served by two complementary pairs of Sanken transistors – 2SC3519A / 2SA1386A. When working with speaker systems with a nominal impedance of 8 Ohms, the output stages up to a power of 10 W operate in pure class A, and with a further increase in volume, the amplifier smoothly switches to AB mode.

The strength of the Vincent SV-237MK is its incredible sound realism. While listening, you get the feeling that you are at a live concert. Moreover, this feeling is difficult to dissect into components – the components do not differ in outstanding localization of instruments on stage or special accuracy in conveying the acoustic features of the hall. Rather, on the contrary, music is perceived directly, without the influence of external factors. The sound canvas is drawn with confident and clear strokes. Without neglecting the smallest details and carefully conveying to the listener all the information included in the recording, the amplifier strictly follows the given course, without being distracted by particulars. This kind of character is more typical of professional equipment.
