Power regeneration is a big thing among most serious audiophiles, but is quietly all but ignored in the UK. IsoTek’s EVO3 Mosaic Genesis is on a one‑regenerator mission to prove us Limeys wrong.

The AC power (or ‘mains’ as we like to call it) is reasonably good across much of the UK. However, ‘reasonably good’ is not in many audiophile vocabularies, and power conditioning and regeneration are starting to be taken seriously here, thanks in no small part to the work of IsoTek. The EVO3 Mosaic Genesis is a hybrid, with feet in both camps, pulling together some of the technology from IsoTek’s top EVO3 Genesis ‘generator’ and Super Titan conditioner.

A power regenerator essentially takes the waveform of your AC mains, references it against a built-in sine-wave generator, then amplifies that signal to deliver a synchronous, DC-offset-free, 230V AC power, with a voltage variation of just a few per cent. This last point is more important than people often consider: given the best guarantee you can get from the power companies in the UK is 230V is +10% to –6%, which brings the UK in line with EU mains harmonisation legislation, although many power companies still work to the older 240V ±6% standard by default. This variation in power can prove problematic, and with increased demand and competition forcing cost-cutting, the likelihood that the UK retains its ‘reasonably good’ mains is called into question.

The EVO3 Mosaic Genesis regenerator uses a Class AB amplifier and heavy-weight transformer delivering a 230V ±2% voltage (fed from a 20A IEC input), to five power sockets – three for low‑power source components or preamps, and two high‑current SuperTitan derived direct‑coupled outputs for power amps. If in doubt (say, an integrated amp), go with the higher‑power outptu sockets. With EVO3, IsoTek developed a technology called KERP (Kirchoff’s Equal Resistance Path) for equal resistance and power delivery to all outlets. To minimise the chance of noise from the original mains leaking into the regenerated power, copper foil acts a shield between primary and secondary windings on the transformer. The internal wiring uses IsoTek’s new UP‑OCC (Ultra Pure Ohno Continuous Cast) high purity copper solid core internal wire, which is silver‑plated before being insulated with Teflon.

IsoTek’s EVO3 Mosaic Genesis also features 100,000A of instantaneous protection, and a series of voltage‑dependent resistors to protect against AC power spikes – this not only protects devices plugged into the EVO3 Mosaic Genesis, but also prevents the regenerator from acting like a big, expensive fuse in times of crisis.
