Ashly's all-new proprietary D-MAX technology brings together smart and cutting-edge amplifier design, a brand-new ultrafast switching power supply with silicon carbide semiconductors and diodes, and intelligent power management to deliver ultimate efficiency.

• When current and voltage are exactly in phase, current demand is reduced and efficiency increased. Dynamic Power Factor Correction tracks current continuously to maintain accurate monitoring and control.
• Silicon carbide semiconductors boost both speed and efficiency and are significantly faster than the old-school pure silicon of the past.
• Traditional silicon semiconductors don’t shut off instantly. They have a lag time called Switching Loss, leading to a residual tail current. From an audio-quality standpoint, this makes for a sloppier, less precise sound; from an efficiency standpoint it sucks up unnecessary power.
• Instead, Ashly is pioneering the use of silicon carbide semiconductors. They have unique electrical characteristics that render them able to switch on and off far faster than conventional silicon. The result is an amplifier design that’s faster (has better audio fidelity) and is more efficient.

• Power amplifiers need cooling. In most amps, heat-reducing airflow takes a convoluted path in and around internal components. Front-to-back, back-to-front, or side-to-side, those nice perforated grilles look simple until you look inside the amp and see the helter-skelter airflow.
• Ashly didn’t want cooling air to just wander around inside the EcoTour chassis, so it came up with its unique SailFlow architecture, which directs internal airflow strictly over the areas that generate the most heat, rather than arbitrarily over the whole amp. This keeps the already highly efficient EcoTour Series even cooler and assures reliable, stable operation, even under heavy loads.
