Ferrum Audio – Wandla HP Dac with Headphone Amplifier

“With Dynamic Digital Filtering, DDF in short, digital filter maker Signalyst, famous for their HQPlayer app created filters exclusively for Ferrum. At the introduction WANDLA HP will feature two special filter options. We will engage with our community to make new filters available, one by one. Doing this we create a new community of digital filter specialists by interaction with us and their WANDLA’s, in search of the best possible, tailor-made sound. This is truly unique to Ferrum, to the category of DA converters and to the hifi community in general.” Marcin Hamerla Founder and CEO HEM

Unique output cable design: two wires delivering the power and two wires providing the feedback to ensure flat voltage at every moment. We named this technique Ferrum Power Link (FPL) and it eliminates the harmful effects of the cable’s resistance effectively improving transient response. The current delivery speed at the powered device’s input is significantly improved.

WANDLA HP comes with a carefully selected DC power adapter. To get the most out of WANDLA HP you can connect it with HYPSOS using our proprietary Ferrum Power Link DC power cable. This FPL cable can be ordered separately.

Fully Balanced HP amplifier
WANDLA HP offers a fully balanced, composite IC headphone amplifier design, fine tuned for WANDLA HP.

Powerful
WANDLA HP’s headphone amplifier can output a hefty 3.5 Watts at 50 Ω (balanced).

Dynamic
WANDLA HP’s headphone amplifier has an impressive dynamic range of 122 dB.

Tomorrow’s High-End Audio Today
WANDLA HP leads the way for tomorrow’s high-end, offering flagship audio quality at an unprecedented price level.

Finely tuned DA conversion
WANDLA HP is the latest exemple of Ferrum’s digital know-how and our in-house-developed analogue audio and electrical technology. The ESS Sabre ES9038PRO combined with Ferrum’s advanced new current-to-voltage (I/V) converter compares to units many times its price.

SERCE
Digital audio system module – Our optimized ARM chip offers the shortest signal path possible, making 5 chips redundant. Includes MQA decoder/renderer and digital filter selection.

Dynamic Digital Filtering
WANDLA HP has a selection of digital filters specially prepared for Ferrum by renowned filter-maker HQ Player. More will follow with future updates after interaction with WANDLA users

Optimized Digital inputs
Specially programmed USB, and tuned coaxial and optical S/PDIF, AES, ARC (TV) and I2S ports, optimized for audio.

Proprietary amplification
Fully balanced modified IC pre-amplifier, fine-tuned for WANDLA HP.

Truly Balanced
Whole signal path is truly balanced inside WANDLA HP. Even when using RCA inputs, the signal is converted to balanced on the input first active stage.

Ease of use
Newly developed hi-res touch screen with intuitive UX that is a dream to operate, including remote control.

Enhanced transparency
The whole design is focused on a balanced and very transparent sound signature, making listening fatigue a thing of the past.

Made for HYPSOS
WANDLA HP performs beautifully right out of the box, but you can take its performance above and beyond when pairing it with HYPSOS. Using the proprietary Ferrum Power Link (FPL) connection with 4T voltage sensing, both components will perform to their absolute maximum, unleashing unheard-of musicality.
