Clarity Pro 2.0

  • Field generator
  • Coherence Technology™
  • Fully user adjustable
  • Brand new circuit design
  • Supplier power supply upgrade

The new Clarity Pro 2.0 is one of a family of products termed ‘field generators’. Not a mains filter or conditioner, these field generators are designed to sit close to your system and radiate a pre-programmed field to reduce the effect of stray electromagnetic fields. We’ve been big fans of these since Russ first heard the original QRT Quantum Symphony at the Consumer Electronics Show (CES) in Las Vegas in 2006, and we added it to the range later that year.

Fast forward a number of years, QRT was then replaced by an a new, updated and more effective design - this time produced in conjunction with ourselves - the hugely successful Clarity Pro. Component supply shortages, however, led to a break in production that saw us re-introducing an update on the original Quantum Symphony, the new Symphony and Symphony Pro.

Last year, however, the core designers of the Clarity Pro contacted us to say that they were working on prototypes for a new generation of field stabilisers. They had designed a new circuit and made changes to the internal software that, they told us, resulted in a stronger, more powerful unit. We were intrigued and worked with them on the design (we were involved at this prototyping stage), to fine tune the circuit.

The new design of the circuit board is a little larger than the original Clarity Pro, so we manufactured a new, custom-designed ABS case. Clarity Pro 2.0 is powered by a separate power supply – a ‘wall-wart’ type, 12V DC supply is included or, for best performance, Clarity Pro 2.0 can be supplied with one of our Supplier DC power supplies.

Clarity Pro 2.0 in use

Using the new Clarity Pro 2.0 couldn’t be easier. It’s designed to work in conjunction with any existing mains filters – it doesn’t replace them.

The key to using it is its position. Ideally, sit it close to your components – a spare shelf on your Hi-Fi rack is ideal, but it can also be put on top of components if there’s room. There’s no harm in positioning it behind or just to the side of your rack if there isn’t room on your shelves.

A single control knob is provided on the front of the unit to adjust the strength of the effect. The pattern and duration of the field is preprogrammed, use the area control to set its strength.

We found that one Clarity Pro 2.0 is sufficient for almost all systems – unlike the older Clarity Pro, there’s no additional benefit to be had from using more than one unit.

Advanced Features

There is a comprehensive number of adjustable parameters available to fine tune the Clarity Pro 2.0. As well as the obvious external Area Control knob, there is also a bank of internal dip swiches which allow you tune your Clarity Pro 2.0 to your personal taste.

About the technology

Not a mains filter or enhancer, the Clarity Pro 2.0 is a field generator that has the effect of stabilising electromagnetic fields. The designers explain that it does this via their proprietary Coherence Technology™ modules – these are the components that generate the field in a specific pattern and duration. The strength of the field generated can be adjusted with the control on the front of the unit.

Overall Impressions

The Clarity units have the subjective effect of ‘calming’ the overall musical presentation and the new Clarity Pro 2.0 is no exception. On receiving the first prototype, Russ thought it a major improvement over the older Clarity Pro and Symphony models. As well as providing a calmer atmosphere, meaning that the music is more relaxing and enjoyable to listen to, he found that the improvements to the musicality – the increased appreciation of rhythm and timing – are what really stood out. Another benefit was with recordings that had previously sounded ‘fierce’, making them less harsh and, again, more enjoyable to listen to.

While the Area Control can be adjusted once and left, Russ found that some recordings benefitted from a stronger field (i.e. they benefitted from being ‘turned up’), while others sounded best with it turned down. Trust your ears – if it sounds better, then it is better!

Yes, I recommend this product.
"Far, far greater improvement than expected; quite amazing!"
Plug it in and simply put it near the Hi Fi? It doesn’t sit across the mains or do any filtering or smoothing. Bonkers! So bonkers, in fact, it just had to be tried!

Bearing in mind the Russ Andrews 60 day guarantee, the order was placed. It came with the standard wall--wart power supply and was placed in the middle of my equipment. I set the control knob in the middle, as suggested.

My equipment is all valve with a record player as the source. It already sounded pretty good so, although I was hoping for an improvement, I wasn’t expecting much.

Well, how wrong can you be?!

With the Clarity switched on the system sounded fresher, more alive, faster and easier to listen to. The soundstage became more defined, with more space round the instruments. Bass became tighter and more tuneful, allowing everything else to come through more clearly. There was also a significant increase in the front-to-back stereo imaging.

Quite amazing!

When the Clarity was turned off the sound returned to its previous presentation. Very good, but not as open and real.

Next step was to try the dedicated 12v supply from Russ Andrews. Again, the 60 day guarantee persuaded me to give it a go.

With the Supplier in place the Clarity didn’t do anything different, just loads more of what it was doing before. The Supplier was not going back!

I have no idea how it does what it does. But then I’ve no idea how the AbZorbers, Purifiers and other gizmos in my system work. All I’m interested in is how it sounds.

I’m very pleased with the hugely positive effect the Clarity has had on my system. Listening to music is now an even greater pleasure.

If you haven’t got one, give it a go! You won’t know how good your system can sound until you try it.
