Интегральные усилители — Vincent SV-600

The SV-600 is a two-channel amplifier in the Solidline range from Vincent, pairing a transistor output stage with a fully balanced design and classic needle VU meters on its fascia that display output level in real time. Its initial watts come in class A before the amplifier moves beyond that region at higher output.

Key specs that matter

Vincent rates the SV-600 at 2 x 200 W into 8 ohm and 2 x 306 W into 4 ohm, with the first 2 x 10 W into 8 ohm in class A. Frequency response is 20 Hz to 20 kHz within plus or minus 0.5 dB, THD is below 0.1 percent and S/N is above 90 dB. Input sensitivity is 220 mV at an input impedance of 47 kohm. The chassis is 430 x 150 x 448 mm and weighs 21.9 kg, and maximum power consumption is 820 W. Buyers choose black or silver.

Engineering and use context

Connectivity is broad for a two-channel amplifier. Analogue inputs include five stereo RCA sources and one stereo XLR balanced input, plus two stereo main inputs that bypass the preamplifier section. Digital sources connect through one HDMI ARC input without CEC, one optical, one coaxial and Bluetooth. Outputs consist of one stereo pre out and four pairs of speaker terminals, which allow two sets of speakers or bi-wiring, together with two 3.5 mm power control jacks for switching linked Vincent components. The high maximum draw indicates a large power supply feeding the output stage, and the weight reflects the heavy transformer and heatsinks needed for the rating. Vincent pairs the SV-600 visually and functionally with the CD-600 CD player in the same range. Because the class A region is small, normal listening at modest level stays in class A while peaks draw on the full rated output. Its fully balanced layout carries audio in two opposite phases through the amplifier, which works naturally with the XLR input. The VU meters give a direct visual check of output level against the rating.

Pairing

The high low-impedance rating makes the SV-600 a candidate for low-sensitivity floorstanding speakers or large two-way designs that need current, while the balanced XLR input suits a source with balanced outputs. Through HDMI ARC a TV can share the system, and the main inputs allow an AV processor to use the power stage for the main stereo pair in a combined stereo and cinema setup.

Alternatives

The Vincent SV-737 is a hybrid integrated model with class A operation that places tubes in the signal path for those who prefer a hybrid design.
