Adagio 300B - Amplifier

Adagio 300B is Auris’ purest expression of classic triode performance — a single-ended 300B amplifier engineered for emotional realism, harmonic richness and a fluid, effortless musical presentation. It captures the essence of vintage tube magic, but with the mechanical precision and build discipline that define modern Auris engineering.

The heart of the Adagio 300B is its carefully matched 300B triodes, chosen for their natural midrange glow, three-dimensional imaging and refined micro-detail. The amplifier delivers a relaxed but deeply engaging sound signature: vocals gain presence, acoustic instruments feel lifelike, and the entire stage breathes with natural warmth and spatial openness.

Auris’ characteristic build quality is fully present. Solid wood panels provide resonance control, hand-finished leather adds structural stability, and a precision-machined aluminium chassis ensures long-term reliability. The internal architecture is kept intentionally short and clean, minimising signal loss and preserving the purity of the 300B topology.

Adagio 300B excels in high-efficiency loudspeaker systems and dedicated listening rooms where nuance, texture and intimacy matter more than brute power. It’s a reference piece for audiophiles who want analogue beauty at its most refined.

Within the Auris collection, Adagio 300B stands as the “emotional flagship” — crafted for timeless listening and perfectly aligned with the high-end experience YourAudio brings to the market.
