Balanced Power BMU-2500 | Factor One

The best way to extract the full potential Audio and Visual quality from any Hifi or Home Theatre system is to balance the mains. A Balanced Mains Unit (BMU) doesn’t provide the voltages to the equipment in a conventional manner. In an ordinary power supply, extension or direct wall connection...

I stumbled onto this exceptional small business in a review & so glad I did. After some insightful back & forth emails, I decided to have Dan build a custom 2500 watt,10 outlet, highly upgraded balanced mains unit. It is called BMU 2510se & it’s not even on the Factor One website yet. His passion for his work is contagious, as he kept me apprised of the build by sending me photos from his bench. Very nice touch Dan! The very first 2510se serial #0001 arrived in the States well-packed in tip top condition 2 weeks ago. As it settles in, I’m struck by the quiet confidence that it can handle anything you throw at it without breaking a sweat! Center image, which drifted a bit with the addition of the fabulous Heartsound Holostages, is once again well anchored. Soundstage is significantly deeper with layering & location of performers more defined. Highly revealing. Bass is huge! Had to back off the REL. After only a couple of weeks, it’s clear to me that the Balanced Power Factor One BMU 2510se is a thoughtful, capable, beautifully crafted & essential addition to my kit. Check ‘em out! More later…

Specs for Factor One BMU-2510se is a 10 socket version of our Award Winning BMU-2500. The SE or “Special Edition” in terms of this BMU-2510SE custom & takes the performance even further.


  • The heart of the BMU-2510SE is a bespoke carefully crafted, extremely tight tolerance balanced toroidal transformer with 4 layers of shielding. We work closely with the manufacturer to ensure that all of our transformers conform to our exacting standards and from one transformer to the next measurements fall within the smallest of margins making one transformer arguably identical to each and every consecutive build.
  • The input socket is a 20A Viborg Pure Copper with 5 layers of Gold Plating C20 type IEC for maximum line input conductivity.
  • Our inrush protection and soft-start circuit is cleverly built to slowly over a 4.5 second period allow the transformer to charge with any sudden fluctuations which can trip consumer units and harm connected equipment. The unique design means that once this process is completed a relay ‘click’ can be heard and the circuit then moves out of the way, not to interfere with the incoming power any longer.
  • Our DC removal circuitry is fast acting and allows for large amounts of DC to be shunted to ground. We use Mundorf Silver capacitors and resistors alongside high current Schokty diodes to ensure a reliable and transparent route to a clean pathway for the incoming live circuit to thrive, small notches in the waveform caused by the incoming DC are then intelligently rebuilt by additional circuitry on the fly to remove any residual distortion.
  • All PCB tracks are gold plated copper.
  • Custom produced gauge specific to our requirements Neotech UP-OCC in Teflon wiring is used across all input and output power lines. The specific gauge alleviates the bass bloom of thicker gauge cables along with loss of leading edge precision. In comparison to thinner gauge cabling our specific strand formula negates leanness of the upper bass, restricted dynamics and an over/emphasis on the top end - allowing for a more balanced and Coherant performance.
  • Heavily silver plated copper earth wire - the material allows for a very high-speed earthing solution with incredibly low resistance.
  • All wiring looms are starred, there is no series wiring anywhere.
  • A high conductivity Biborg Pure Vopper Gold Played earthing piston sits at the rear to allow other sources of grounding to all utilise the BMU-2510SE’s master ground point reference.
  • Alongside this reference ground is our own large grounding box with a massive 4.35kg of material in an ABS copper lined enclosure which feeds into the grounding system directly at its star point to condition and lower the noise floor even further.
  • Safety is paramount, so the rear panel switch is a dual circuit breaker capable of shutting down all the output sockets in the event of a short. This circuit breaker is an audiophile grade product which utilises gold traces and input output terminals with magnesium relays.
  • The Power Output Sockets are Viborg Pure Copper with 5 layers of 24ct Gold Plating to give an unimpeded low resistance, high conductivity output.
  • The chassis itself is made from CNC cut sheets of aircraft grade aluminium for its strength and inert abilities . This material is lined with a damping material to eliminate high-frequency resonances even further.
  • The feet on the underside are a version of our OMEX equipment supports. They are produced using an Aluminium Polymer Compound which fat exceeds the ability to remove resonances over a standard aluminium. Sandwiched between these layers is an array of ceramic balks to help dissipate vibration as heat.

More info on Factor One Balanced Power

Each of the models will supply a continuous 20 amps with absolute ease.

They also offer continuous 25 amp models. Anything after that becomes more custom due size and weight.


I have the very first custom BMU 2510se in the States. Word is getting around however!
