Musical Fidelity X-Power Power Conditioner Combines Surge Protection, EMI/RFI Filtering and DC Blocking

From a construction standpoint, the cylindrical aluminum enclosure is more than a visual callback to the X-Line. A single-piece extruded housing provides both mechanical rigidity and effective electromagnetic shielding, reducing the risk of the filter itself becoming an antenna for airborne noise. Internally, the separation of surge protection, HF suppression, and DC blocking into discrete stages suggests a modular mindset: each problem is addressed independently, rather than through a one-size-fits-all network. The DC-blocking circuit in particular speaks to a real-world issue many audiophiles encounter—toroidal transformers reacting badly to asymmetrical mains—without resorting to complex active solutions.

Seen in the broader context of Musical Fidelity’s recent products, the X-Power complements rather than replaces traditional power solutions. It aligns with a school of thought commonly voiced in forum discussions: clean up what actually matters in the mains, then get out of the way. By encouraging users to think in terms of dedicated supply paths—either for a single amplifier or for a carefully grouped front end—the X-Power reinforces a system-level approach to power that goes beyond accessory tweaking and into fundamental infrastructure planning.
