Description
WANDLA HP builds on the acclaimed WANDLA DAC/PREAMP by integrating a powerful, fully balanced headphone amplifier capable of delivering 3.5 W into 50 Ω. This makes it ideal for music lovers who want a single, elegant unit that handles both headphone and speaker listening without compromising on performance.
At the heart of WANDLA HP is Ferrum’s proprietary SERCE digital audio system. This ARM‑based platform processes all incoming digital data streams and replaces five separate chips, creating the shortest possible signal path for USB, ARC, I2S, coaxial and optical inputs. Combined with the ESS Sabre ES9038PRO DAC and Ferrum’s advanced current‑to‑voltage converter, the result is a level of transparency and musicality that rivals far more expensive systems.
Dynamic Digital Filtering, with filters specially prepared for WANDLA by Jussi Laako of HQ Player, gives users multiple high‑end filter options with more to come through future updates. The analogue stage benefits from Ferrum’s experience developing the acclaimed OOR amplifier, ensuring a balanced, fatigue‑free sound signature.
A newly developed high‑resolution touchscreen and intuitive interface make operation effortless. WANDLA HP includes six digital inputs, an unbalanced analogue input, balanced XLR and unbalanced RCA outputs, and dual DC power inputs. It performs beautifully with its included power supply, and reaches even higher levels when paired with Ferrum’s HYPSOS using the proprietary FPL connection.
