Furman IT-Reference 16Ei Power Conditioner (HiFi-Plus 67)

The Furman IT-Reference 16E i is called a ‘discrete symmetrical AC power source’. It has eight isolated IEC sockets for low-level analogue, digital or video sources, four high current isolated sockets (three 10A, one 16A) for power amps and eight connectors for satellite or radio sources. And inside the box is enough dual-screen transformer action to make the damn thing weigh so much.

The IT-Reference 16E i has a soft-start. If your lights dim when powering up, you need one. Also, if you have anything with transformer hum (like using a product designed for 220v in the UK, where 240v is commonplace), the IT-Reference 16E i power conditioner is often an effective cure.

It doesn’t undermine the performance of connected equipment. There’s no sense of music sounding weedy and breathless in dynamic passages, although there is a small amount of the sound being slightly ‘pumped up’ when playing quiet passages. But, given the alternative is the quiet passages battling a less quiet noise floor, the times when the IT-Reference 16E i is called for, it’s a useful addition. At its best (or rather, when it’s most needed), it gives the midrange more freedom, the bass more impact and the treble less grit; not significantly, not like the difference from swapping from one pair of speakers to another, but enough to make its presence felt.

Living in suburban London though, the power conditioner did significantly improve the mains during key early evening moments (where every neighbour was watching TV, on that t’internet, listening to music or cooking) and that was a significant bonus. Even here, some products (mid-priced solid state electronics) needed the firm hand of the Furman more than others (valve amplifiers). And then, during those two heady days of high summer, we got some short on-again, off-again short, spiky power cuts (using semi-skilled mole people to attempt to fix Victorian water mains makes these brown outs irregular, but annual local events). With the Furman in place, no fuses blew in the system, and both light circuits tripped. The same thing happened a few months earlier. Both light circuits also tripped then, and two fuses blew in a very similar system. Anecdotal, of course… but that does suggest the Furman is adding a level of protection to products under its very heavy wing.

The Furman IT-Reference 16E i power conditioner might just be the real-world antidote to ‘foo’ mains products. When you need it, it does what it’s supposed to; when you don’t, it doesn’t get in the way. There are a lot of products that claim more and deliver less.
