Vincent Audio SV-737MK Hybrid Stereo Integrated Amplifier

Vincent SV-737MK: The Flagship Hybrid, Now Ready for Your TV

The Vincent SV-737MK is the updated version of Vincent's flagship hybrid stereo integrated amplifier. A tube preamp stage feeds a high-power transistor amplifier, delivering 180 watts per channel into 8 ohms and 300 watts into 4 ohms, with the first 10 watts per channel into 8 ohms in Class A.

Based on customer feedback, Vincent reworked the connections. An HDMI ARC input replaces the old Wi-Fi module, so your TV plugs straight in, and a dedicated pre out and Main In input replace the earlier jumper links. Inside, the proven circuitry carries over. It comes in Black or Silver.

Five Tubes in the Preamp and Power Supply

The preamp uses two gain blocks with a switchable tone control. 6N2P double-triode tubes handle voltage amplification, and two 6N1P tubes with high-current cathodes serve as the driver and buffer stages. The high-voltage supply, adopted from Vincent's SA-T7 MK preamp, pairs an 85A2 voltage reference tube with a solid-state regulator for a low-noise, virtually hum-free supply. A lit front window shows the tubes, and the remote dims or turns off the light.

A Power Stage Built From the SV-237MKII

The power section is based on Vincent's SV-237MKII, with an optimized input cascode circuit for better transient response into complex speaker loads and more output power. Vincent says the combination with the tube preamp gives a sound reminiscent of high-quality single-ended triode amplifiers, with far more power.

Built-In DAC, HDMI ARC, Bluetooth and a Headphone Jack

A built-in D/A converter takes two optical, two coaxial and one HDMI ARC input. Bluetooth streams from your phone or tablet. On the front, a 6.3 mm headphone jack drives headphones from 32 to 600 ohms and switches the speakers off while you listen.

How the SV-737MK Fits Your System

The SV-737MK is a complete stereo amplifier: connect your sources and speakers, and you are ready to play. Speaker A and B buttons let you run one pair, the other, or both. One pair can be 4 ohms or higher; when you run two pairs together, every speaker must be 8 ohms or higher.

The Main In input (RCA) bypasses the preamp, so a home theater processor can use the SV-737MK to power your front left and right speakers. A pre out can feed a second amplifier, a record out feeds a recorder at a fixed level, and two 12V power-control outputs switch other components on and off with the amp.

What it will not do: there is no phono input, no XLR balanced input, and no Wi-Fi or network streaming. Its HDMI ARC input does not support CEC, so your TV remote will not change its volume.

Who Is This Integrated Amplifier Best For?

• Listeners who want tubes and power — a tube preamp with 300 watts per channel into 4 ohms.
• Music and TV in one room — HDMI ARC and optical inputs bring in TV sound.
• Home theater fans — the Main In input lets a processor drive your front speakers.
• Headphone listeners — a front 6.3 mm jack for headphones from 32 to 600 ohms.
• Not for — anyone who needs a built-in phono stage, balanced XLR inputs or network streaming.

How Does It Connect to Your System?

• Connect your speakers to the Speaker A terminals (and Speaker B for a second pair). The terminals accept 4 mm banana plugs, spade lugs or bare wire.
• Plug analog sources into the five RCA inputs.
• Connect a TV to the HDMI ARC or an optical input, and other digital sources to the coaxial or optical inputs. Use the ANALOG/DIGITAL button to switch between analog and digital inputs.
• Screw on the included Bluetooth antenna, select the S3/BT input and pair your device with "Vincent".
• Leave about 5 cm (2 in) of open space around the amp for airflow, and place it on a rack shelf rather than stacking other gear on it.

Pairs Well With

Complete your system:

• Floorstanding speakers — put 180 watts per channel to work.
• Phono preamplifiers — to add a turntable on a line input.
• Headphones — any pair from 32 to 600 ohms works with the front jack.
• Speaker cables — banana or spade terminations fit the terminals.
• Audio racks — a sturdy shelf with room to breathe.

Frequently Asked Questions

What changed from the original SV-737?

The connections. HDMI ARC replaces the Wi-Fi module, and a dedicated pre out and Main In input replace the jumper links between the preamp and power amp sections. Vincent kept the proven circuitry.

Which tubes does it use?

Two 6N1P, two 6N2P and one 85A2.

Can I connect my TV?

Yes, through the HDMI ARC input or an optical input. The HDMI ARC input does not support CEC, so use the Vincent remote for volume.

Can I turn off the tone controls?

Yes. With the TONE button released, the bass and treble controls are bypassed.

Does it turn itself off?

Yes. It switches off after about 15 minutes without use. You can turn this off with the AUTO switch on the back panel.

What comes in the box?

The amplifier, a power cable, a remote control, a Bluetooth antenna, a 3.5 mm power-control cable, an optical (Toslink) cable and the manual.
