The Legend Returns
A decade after the original captivated listeners worldwide, Auris Audio proudly presents the Fortino 6550 – 10th Anniversary Edition.
Faithful to its roots yet re-engineered for the future, this amplifier embodies the perfect harmony between tradition and innovation.
Modern Craftsmanship, Timeless Soul
The new Fortino remains true to the elegant design language that made it iconic, while introducing subtle yet significant refinements:
- 5” OLED display with dual VU meters, tube-life monitoring, and intuitive menu navigation
- Balanced (XLR) input for purer signal transmission
- Upgraded power supply for greater dynamic stability and ultra-low noise floor
- Extended frequency response through newly developed output transformers
- Precision CNC-machined aluminum chassis, now resting on custom rubber damped stands to minimize external vibrations
Every detail is designed to elevate both form and function — the Fortino now looks as good as it sounds.
The Power of 6550 — Refined
Driven by four 6550 output tubes in push-pull / ultralinear configuration and four ECC82 drivers, Fortino delivers 50 watts per channel of pure musical authority.
Its auto-biasing circuit ensures perfect tube balance, extended lifespan, and effortless reliability — letting you focus on music, not maintenance.
“Auris builds well, and builds heavy. Reassuringly heavy. The Fortino looks better in real life — and sounds even better.”

From intimate jazz ensembles to complex orchestral recordings, the Fortino remains stable, composed, and captivating.
