What is Coherence Technology™?

Russ has been a big fan of electromagnetic field stabilisers (Coherence Technology) since we started selling the original QRT Quantum Symphony back in 2006.

Not really a mains filter or conditioner in the traditional sense, these ‘enhancers’ are small boxes designed to sit close to your system and reduce the effect of stray electromagnetic fields. The manufacturers tell us that by generating their own, lower-frequency field, the devices effectively ‘tune’ the RF noise to improve fidelity. Our own listening tests proved to us how effective they are.

The original manufacturers of Quantum Symphony sold their business about 10 years ago, but we were pleased to find a related product, the Clarity Pro, which offered a similar approach. We’ve had very many enthusiastic users (including Russ) of the Clarity Pro until it was discontinued earlier in the year. So imagine our delight when the original manufacturer of the Symphony contacted us to say he had set up a new company to offer two new, completely re-designed Symphony models!

Enhancers like these work on the principle of ‘coils’ to generate their fields – they are the part of the component that does the work. There are two new Symphony models – the standard Symphony which features four coils, and the Symphony Pro which has six (by contrast, both versions of the older Clarity Pro had just three). The electronics are mounted in compact cases which can sit anywhere in the listening room, though we like to have them positioned close to the system, and preferably behind. Each unit comes with an antenna that can optionally be used to adjust and strengthen the effect.

We had very good results with the units on test. The music was calmer, there was more information and it was easier and more enjoyable to listen to. Both units made the sound richer, more like a live performance – there was simply more access to the music. We liked the effect of the Symphony; and we loved the effect with the Symphony Pro!

Using the Symphony Pro

Symphonies address the problem of mains noise in a different way to our other conditioners and filters and work very well in conjunction with our existing Silencers, Purifiers, Clarity Mains Units and Zapperators – and those from other manufacturers too. They also work well with our Balanced Mains Units if you have these.

The Symphony Pro comes fitted with a higher-quaility, internal power supply and get-you-going mains cable - we'd recommend upgrading this to our yellO Power mains cable for even better performance N.B. you will need to use this with a Cloverleaf Adaptor.




Start by placing the Symphony Pro in a central location within your Hi-Fi. Once connected and powered up, have a good listening session. Then experiment by adding the antenna.

Using the antenna is optional but recommended and there are a couple of suggested ways the antenna can be fitted in your system. The first is to fix it to the wall behind your system, if the wall is close enough; the second is to split the wire into two (it pulls apart) and drape it horizontally over speaker cables – one half over one speaker cable and the other.

"Subtle, But Worth It!"
I am lucky to have a high end system which creates awesome music. However, having read reviews about Add Powr, I had to try the Symphony Pro and yes, I'm pleased I did. Even more musical detail is forthcoming and money well spent.
I'll have to try another now by my NAS and switch!

"Transformation, Or How I Discovered A “New” Piece Of Equipment"
I occasionally wonder if I am too generous with my reviews of the equipment I buy from RAA and whether it is worth the asking price. However, I am usually confounded.
Suddenly, live broadcasts (HD quality) became “present” with more space and air around instruments, precise locations of soloist and wind players and just a total feeling of involvement. The experience with CDs is proving to be much the same (thank goodness). The colours on my monitor are richer, clearer and have more depth (when I tested by switching off the Pro, colours immediately became duller. So yes, expensive but worth every penny - a “new” piece of equipment that increases your appreciation of what you already have
