Vincent Audio SV-237MKII Hybrid Stereo Integrated Amplifier

Serious Power, Tube Character

The SV-237MKII is the muscle car of Vincent's hybrid lineup. A tube preamp stage feeds a serious solid-state amplifier section. That section is rated at 150 watts per channel into 8 ohms. Into 4 ohms it climbs to 250 watts.

A dedicated Class A mode delivers 10 watts per channel. Use it for late-night listening at low volume. That is where Class A's linearity matters most. The full-power mode stands ready for anything your speakers demand.

Where the Warmth Comes From

One 12AX7 and two 6N1P tubes shape the preamp stage. Vincent chose them for the naturalness and warmth they bring. They work on the signal first. Only then does it reach the transistor output section.

It is the same hybrid formula that runs through Vincent's lineup. Here it is scaled up for speakers that need real current behind them. Three RCA inputs, optical and coaxial digital inputs, and Bluetooth cover a full range of sources. Preamp and record outputs let you add a power amp or a recording device later.

Built Like the Reviews Suggest

At 45 pounds, the SV-237MKII carries real mass. The chassis is machined, and it comes in black or silver to match the rest of Vincent's tubeLine series. Dual speaker terminals per channel support bi-wiring. Two 3.5mm power-control jacks let it work with automation systems in a multi-component rack.

The limited US warranty covers two years parts and labor, with 90 days on the vacuum tubes, and applies to the original owner. Proof of purchase may be required. Save the original box and packaging to ensure safe transport if the unit ever needs service.

What Reviewers Are Saying

Craig Chase reviewed the SV-237MKII for Secrets of Home Theater and High Fidelity on February 19, 2024. He wrote that "Everything about the Vincent 237MK II is first class." His verdict: "Think of it as a five-star performer with a three-star price!"

Chase found it "can hold its own with a variety of high-end speakers." He worked hard to find a fault, and came up with one: "it only has two digital inputs."

Who Is This Integrated Amplifier Best For?

• You need real power with tube character — 150 watts per channel with a tube preamp stage shaping the sound.
• You listen quietly some nights, loudly on others — a dedicated Class A mode for low-volume listening, full power on tap otherwise.
• You're matching demanding speakers — reviewers paired it successfully with speakers well above its own price point.
• You want room to expand later — preamp and record outputs support adding a power amp or recorder down the road.
• If you need a phono input, the SV-237MKII is line, digital, and Bluetooth only — one of our phono preamplifiers adds that connection.

How Does It Connect to Your System?

Connect your speakers to either set of binding posts, using both for bi-wiring if your speakers support it. Three RCA sources fill the analog inputs, digital sources join by coaxial or optical, and your phone pairs over Bluetooth. The preamp and record outputs stand ready whenever you add a power amp or recording device.

Choose Class A for quiet evenings, full power for everything else.
