Vincent Audio SV-500MK Stereo Integrated Amplifier

The Hybrid Classic, Updated for Today

The Vincent SV-500MK carries forward what made the original SV-500 a favorite. A tube preamp stage feeds a solid-state power section. That is the hybrid part. The chassis around it is compact and nicely machined.

Three tubes handle the preamp duties. One is a 12AX7. The other two are 6N1. Vincent biases them conservatively, which works out to roughly a decade of service before they need attention.

Fifty Watts a Side, Eighty Into 4 Ohms

The power section is rated at 50 watts per channel into 8 ohms. Into 4 ohms it delivers 80 watts. Preamp and record outputs sit on the back panel. If you already own a separate power amp, the SV-500MK can work as a standalone tube preamp.

Headphones and Tone, Without Leaving the Chair

A headphone jack sits on the front panel with its own independent control. When the speakers need to stay quiet, the SV-500MK doubles as a personal listening station. Bass and treble controls handle simple tone-shaping from where you are sitting.

Stream, Plug In a TV, Skip the Soundbar

The MK update brings the SV-500 current. A Burr-Brown PCM5102 DAC now decodes digital sources. It handles up to 24-bit/192kHz over coaxial or optical. Bluetooth 5.0 adds wireless streaming on top of that.

An HDMI input with ARC joins them. Your television can send audio straight to the amplifier. No separate soundbar or receiver is required. Two RCA inputs round out the analog side.

What Reviewers Are Saying

Dean Seislove reviewed the SV-500MK for Positive Feedback on April 7, 2025. He called the amplifier's Bluetooth performance "exceptional" and "very impressive," hearing "loveliness where other DACs might expose its harshness."

He also praised the amplifier's unexpected reserves of power. Turn it up and it offered "volume on demand" with music rising "with power and impact in proportion to the increased level," he wrote.

He liked the "warmth and filling" sound enough to say that if the stock tubes are responsible, "I would keep them right where they are." His verdict: "The SV-500MK delivers your money's worth and much more, whatever currency you prefer, and you can't ask for better than that. Highly recommended."

Who Is This Integrated Amplifier Best For?

• You want tube warmth in a compact footprint — a hybrid design that doesn't demand a full equipment rack.
• Your TV needs a serious amplifier — HDMI ARC connects a television directly, no soundbar needed.
• You stream from your phone often — Bluetooth 5.0 handles wireless sources with real fidelity, per reviewers.
• You listen on headphones sometimes — a front-panel jack with independent control is built in.
• If you need a phono input, the SV-500MK is line, digital, HDMI, and Bluetooth only — one of our phono preamplifiers adds that connection.

How Does It Connect to Your System?

Connect your speakers to the binding posts and your TV to the HDMI ARC input for one-cable sound. Two RCA sources fill the analog inputs, digital sources join by coaxial or optical, and your phone pairs over Bluetooth. If you already run a separate power amp, the preamp outputs let the SV-500MK work as a dedicated tube preamp instead.

Headphones plug into the front panel whenever the room needs to stay quiet.
