Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Vincent's designs utilize a hybrid approach, often pairing vacuum tubes in the preamplifier stage with solid-state components in the output stage, seeking to combine sonic warmth with reliable power delivery.
- Vincent Audio often employs a separate, custom-made linear power supply in a second chassis, rather than a switch-mode "wall-wart," even in more affordable models.
- Many Vincent products include tone controls, which can be bypassed, offering flexibility in tailoring the sound to different recordings and listening environments.
- The brand's components frequently incorporate a built-in DAC, offering a convenient all-in-one solution for digital sources.

Our summary
Product Strengths
- Ultra-low noise with remarkably quiet backgrounds and effortless transparency
- Delivers Al Harewood's delicate brush work with an outstanding balance of brush "edge" and "swish"
- Clear and distinct sound, with a soundstage that is tall, wide, and deep
- Natural and matter-of-fact nature, one that doesn't feel processed or constrained in any particular way
- The V10 is a highly musical phonostage that resolves fine details, honors tonal colors, and allows the dynamic life in music to breathe at levels that belie the unit's modest price
Product Considerations
- Adjustments to capacitance, gain, and impedance are accomplished by means of a bank of DIP switches on the rear panel, which can be a bit confusing
- The instruction manual states it's possible to set impedance "freely between 50 and 550 ohms" and add 6 addition dB of gain, but to do so contact your Hegel dealer for more information
- Not as versatile as the PS Audio Stellar
- The V10 does not try to mask physical imperfections on the record
Comparisons (according to reviewers)
- Vs Simaudio MOON by Simaudio 610LP—the Hegel V10 performs so well in comparison to the much more expensive 610LP as to be encouraging
- Vs Aurorasound VIDA Prima—the Hegel V10 seemed to pull out more detail than the VIDA Prima
- Vs Aqvox Phono 2 Ci—V10 allows one to easily explore the musicians' context and intent better
- Vs Rega Aria 3—the V10 betters it by quite a way, showing how the Hegel has a more incisive and detailed nature
Takeaway: The Hegel V10 is a great sounding, well-made phono stage that produces the 3D, of both the music and the space behind it, while honoring the purity and simplicity of the recording. It has connectivity and configurability as well.
