Plus, runners up prizes of a Polaris mains conditioner and Initium cables

Here's a conundrum that may well have a ring of familiarity about it to long-term HFC readers: you've spent years putting your beloved system together and are delighted by the perfection you've managed to achieve from your amp, turntable and speakers, but how do you go about squeezing out that extra last bit of quality without replacing the components you've fallen in love with?

Fortunately, help is at hand thanks to power specialist IsoTek, which has been focusing on maximising the potential of the mains supply delivered to our precious audio components since 2001. In the simplest of terms, the thinking is that by cleaning up the quality of the incoming electrical signal and performance enjoys a significant boost. Think of it as the fuel that's required to get the car running – if you want the best performance from a hot hatch or supercar, you need to ensure you're supplying the cleanest 'fuel' possible.

Enter, the Evo3 Sigmas – featuring the combination of IsoTek's Titan for power amplification and Nova for source equipment. It comes equipped with six mains sockets – two for high-current components such as power amplifiers and four for source equipment. Capable of handling 3,680W or 2,300W respectively, the Sigmas is perfectly equipped for dealing provides 108,000A of protection against surges, spikes and other electrical nastiness.

When we saw the Evo3 Sigmas in HFC 394, its inclusion brought about gains in bass performance with a sense of extra speed and agility. The soundstage opened up without losing any of the focus and our reviewer declared that the effect was uncannily like the strapline for Berocca vitamin tablets – my system, but on a really good day.

To get your hands on one, answer the simple question opposite and enter at: hifichoicemag.com. The first name pulled out of the hat will win IsoTek's £3,252 Evo3 Sigmas mains conditioner, the first runner up claims a £395 Evo3 Polaris powerblock and three further runners up take home a £90 masking it from external interference, audio with high-end power requirements and Evo3 Initium cable.
