Russ Andrews got in touch to say they have introduced the new Symphony System Enhancers, which they say: “significantly improve the performance of any hifi or home cinema system, through the use of electromagnetic field stabiliser technology”.

Quantum Symphony

Manufactured by the same people behind the original Quantum Symphony, the new Symphony and Symphony Pro products are compact boxes that are designed to sit close to the hifi system to reduce the negative effects of stray electromagnetic fields. This is achieved, say the makers, through the generation of a low frequency field which effectively tunes the RF noise to improve audio fidelity.

Within the boxes are a number of coils, four in the Symphony and six in the Symphony Pro, which generate the ‘tuned’ fields. Their effect, say Russ Andrews, “is to positively change the performance of electrical devices, specifically affecting the quality of electrical signals, including audio and video, smoothing out the unwanted noise contained within electromagnetic signals and fields”.


The units should be plugged in and situated next to the hifi system. The included antenna can be attached and used to strengthen the effect of the unit, either by fastening it to the wall behind the hifi system or running it alongside the speaker cables. The Symphony is supplied with a ‘wall wart’ power supply and the Symphony Pro features an enhanced, internal power supply. Each unit can be used in conjunction with mains filters, such as the Russ Andrews Silencers, Purifiers, Zapperators and Balanced Mains Units.

Technical director and owner of the business, Russ Andrews, a fan of electromagnetic field stabilisers since the first QRT Quantum products, says of the new Symphony, “I was delighted when the original owners of the Quantum company contacted me to say they were relaunching and introducing these new products and I was incredibly pleased with the results they provided. The music was given a whole new dimension, it was calmer and there was more information present. A richer and wider soundstage emerged too, which was more cohesive, solid and musical. I certainly won’t be removing them from my own system!”


The Symphony costs £399 and the Symphony Pro is £799. Both come with the Russ Andrews 60 Day Home Trial with Money Back Guarantee.
