Ferrum HYPSOS Single-Output Smart Universal Power Supply System at Vinyl Sound Buffalo, New York

The Ferrum HYPSOS Single Output is the original award-winning hybrid power supply system from Ferrum Audio (Warsaw, Poland), available at Vinyl Sound in Buffalo, New York. Winner of the EISA Best Product 2021-2022 Award, the HYPSOS redefines what an audiophile power supply can do by combining a linear and switching topology in a single chassis, with a continuously adjustable DC output from 5 to 30 V and a maximum continuous output power of 80 W at voltages above 13.3 V. Its proprietary 4T Sensing Design measures voltage directly at the load's internal power rail via the Ferrum Power Link cable, continuously correcting for cable resistance and transient current demands that standard DC supplies cannot address. The HYPSOS is compatible with the full range of Ferrum Audio components including the OOR, WANDLA, WANDLA HP, and ERCO Gen 2, and with hundreds of third-party audio devices across the 5 to 30 V operating range.

Hybrid Linear-Switching Topology

The HYPSOS's power conversion stage combines a linear transformer-based section with a switching regulator in a configuration that Ferrum terms a hybrid design. The linear section provides the low ripple, low noise floor, and absence of high-frequency switching interference that audiophile equipment demands, while the switching section contributes fast transient response and high efficiency that a pure linear design cannot match at this output power level. A two-stage EMI filter on the IEC C14 mains inlet provides pre-filtering of mains-borne interference before the conversion stage, further reducing the noise contribution to the DC output. The result is a supply with the noise characteristics of a linear design and the dynamic response of a switching design.

4T Sensing Design and Ferrum Power Link

The 4T Sensing Design is the technical core of the HYPSOS's performance advantage over standard power supplies. Most DC power supplies regulate voltage at their own output terminals, meaning the voltage actually reaching the load's power rails is lower than the set point due to resistance in the DC cable. Under dynamic current demands such as musical transients, this voltage sag worsens further as more current is drawn. The FPL cable's four conductors dedicate two to power delivery and two to a sensing circuit that reads voltage directly at the load's internal rail. The HYPSOS continuously compares the sensed voltage against the set point and adjusts its output to correct the difference in real time, ensuring flat voltage at the point of consumption regardless of cable resistance or current demand. Sweet Spot Tuning allows the set point to be adjusted on the fly during playback for direct comparison at different operating voltages.

Frequently Asked Questions

What is the Ferrum HYPSOS Single Output?

The Ferrum HYPSOS Single Output is a hybrid linear-switching audiophile power supply from Ferrum Audio in Warsaw, Poland. It delivers a continuously adjustable DC output from 5 to 30 V with 80 W maximum continuous output power, uses 4T Sensing Design via the Ferrum Power Link cable to regulate voltage at the load's internal rail rather than at the supply output, and won the EISA Best Product 2021-2022 Award. It is available at Vinyl Sound in Buffalo, New York, as a standalone unit and as an upgrade for the OOR, WANDLA, WANDLA HP, and ERCO Gen 2.

How does the HYPSOS compare to an iFi iPower Elite or Paul Hynes SR4?

The Ferrum HYPSOS, iFi iPower Elite, and Paul Hynes SR4 are all audiophile-grade external power supplies, but they differ significantly in topology and capability. The iFi iPower Elite is an active noise-cancelling switching supply with fixed output voltages, designed for compact low-power components. The Paul Hynes SR4 is a pure linear supply with fixed or semi-adjustable output voltage, known for very low noise but limited output current and no automated voltage sensing. The HYPSOS uniquely combines a hybrid linear-switching topology with a continuously adjustable 5 to 30 V output, 80 W maximum output power, and the 4T Sensing Design that neither the iPower Elite nor the SR4 offers. The HYPSOS also includes full system automation via trigger and Apple TV remote, which are absent from the competing products.

Does the HYPSOS Single Output include the Ferrum Power Link cable?

The HYPSOS ships with a DC power cable in the most commonly used connector size (5.5 x 2.5 mm or 5.5 x 2.1 mm). The Ferrum Power Link FPL cable required for 4T Sensing connection to OOR, WANDLA, WANDLA HP, or ERCO Gen 2 is a separate purchase. The FPL cable is available at Vinyl Sound Buffalo and is required to activate the 4T Sensing Design; without it, the HYPSOS operates as a conventional regulated DC supply via the standard barrel connector. Custom cable lengths are available to order.

What voltage should I set the HYPSOS to when using it with the Ferrum OOR or WANDLA?

Ferrum recommends 24 V as the starting operating voltage for both the OOR and WANDLA when connected via the HYPSOS. The safe adjustment range via FPL is 22 to 30 V. Sweet Spot Tuning allows the user to adjust voltage on the fly during playback in small increments to identify the level at which their specific unit sounds best in their system. Different units may respond differently to voltage variations due to component tolerances, and the optimal level may differ slightly between the OOR and WANDLA. For third-party components, consult the device's documentation for its rated DC input voltage before connecting the HYPSOS.

Can the HYPSOS Single Output power two components using a Ferrum Power Splitter?

Yes. The Ferrum Power Splitter accessory connects to the HYPSOS Single Output and provides two DC output cables for simultaneously powering two components at the same voltage. When using the Power Splitter, both connected devices must be compatible with the same operating voltage and combined power consumption must not exceed 80 W or 6 A. The 4T Sensing Design via FPL cable remains active on one output of the Power Splitter. Users who need two simultaneous outputs as a primary system configuration may prefer the HYPSOS Dual Output, which integrates dual output capability into the supply directly.

Is the HYPSOS software upgradeable?

Yes. The HYPSOS is designed as a software-controlled device with the minimum of hardware-dependent elements, specifically to allow future firmware updates to add features or improve performance over time. Updates are installed via the Ferrum Control App for PC and Mac. This design philosophy reflects Ferrum's broader commitment to long-term product support, as also demonstrated by the free WANDLA 2.0.0 firmware update for all WANDLA models.
