Cayin Jazz 100 Tube Integrated Amplifier Review: A Masterclass in Single-Ended Class A Warmth
Introduction to Our Cayin Jazz 100 Review
Welcome to our Cayin Jazz 100 Tube Integrated Amplifier Review, where we delve into the exquisite engineering and musical prowess of Cayin’s latest masterpiece. Designed around the legendary 805A power tube and operating in Single-Ended Class A, the Jazz 100 delivers 46 watts per channel of pure, musical power. Whether you’re a die-hard tube enthusiast or a vinyl aficionado seeking that perfect synergy, this integrated amplifier is poised to elevate your listening experience.

First Impressions and Design Craftsmanship
From the moment you unbox the Jazz 100, you’re struck by its hand-made construction and stunning anodised aluminium front plate. Fully vented chassis and point-to-point wiring underscore Cayin’s commitment to high-end build quality. Dual retro VU meters grace the face, rhythmically dancing with your music, while top-plate bias adjustment and hum balancer controls put fine-tuning at your fingertips.

Signature Sound and Performance
At the heart of the Jazz 100 are premium Mullard 6JC6 and 6SN7 voltage stages, a 6L6 driver section (user-swapable for EL34, KT88, KT90 and more), and dual 805A output tubes. Single-Ended Class A operation ensures zero-crossover distortion and an organic midrange bloom that audiophiles crave. Bass is taut and controlled, mids are lush and textured, and the treble soars with crystalline detail. Adjust the negative feedback (High/Low NFB switch) to tailor harmonic richness or tighten dynamics to suit your system and genre of choice.
Connectivity, Flexibility & Headphone Output
The Jazz 100 accommodates three line inputs plus hi-res Bluetooth 5.0 with aptX HD, LDAC and UAT support, decoded by the ES9018K2M Sabre32 DAC chipset for wireless streaming at its sonic best. Speaker outputs at 4 Ω and 8 Ω handle a wide range of speakers, and a robust headphone amplifier (16 Ω–300 Ω) allows late-night listening without disturbing the neighbours. All this power comes at a reasonable 410 W consumption, safeguarded by high-voltage fuses and a soft-start circuit for extended tube life.

Who Should Consider the Cayin Jazz 100?
- Tube purists craving Single-Ended Class A warmth and midrange clarity
- Enthusiasts who love to roll tubes—swap 6L6 for KT88, 6550 or EL34 to sculpt your signature sound
- Vinyl lovers seeking a robust, musical integrated amp with analogue charm and modern digital flexibility
- Headphone aficionados wanting a tube-driven headphone stage that can drive 16 Ω ear-cans through to 300 Ω planars
