Coherent Systems Consultancy, Sale and service

I've know Tony for a couple of years. I originally inquired about a Mutec MC3+ and a Ref 10 with a dealer in the North of England, where I live. Tony (Tony is the distributor for Mutec) joined him at my house, a drive of around 250 miles for him. He listened to my system and made some recommendations, some of which were either cheap, or free. He also introduced me to his Coherent cables, for Mains, Digital and Speakers. I bought the MC3+ and Ref 10, and Tony left me with some cables to try at my leisure. After a couple of weeks of trying different cables I chose to buy 5 of the 6D digital (BNC) version. (I also tried the free recommendations and every one improved the sound quality.) These cables are musical, with superb sound stage capabilities and lovely bass. They really are the nicest sounding cables I have found so far, for digital and clock data. Recently I managed to cause a little bit of damage to two of the cable plugs. Tony asked me to return them and he got straight on the case and has turned them around very quickly. So, would I recommend Tony and Coherent systems? Yes, without a show of a doubt. His knowledge is superb, he is a lovely guy who will go out of his way to help the customer and his after-sales service is first class. Like me, many will go and buy what they think is the best available, only to become dissatisfied with the sound quality months later. (For me it was Linn, Naim, Wilson Benesch etc etc as well as some very exotic cable names). They will upgraded and upgrade but never find that sound they are looking for. With a bit of luck, again like me, they will eventually find Tony.

Coherent Systems international sales and service

Buying audio equipment from half way around the world.

I recently inquired about a TAD cd player that I saw on Coherent's website and after a few emails chatting with Tony a purchase was organised.
My reservations about shipping and packaging were answered before I could even ask the questions. The entire packaging and shipping process was fantastic I’m so glad good old fashioned principles and care still exist.

Was equally impressed with the product knowledge and advice I was offered, an absolute pleasure to do business with Tony.

I would without hesitation recommend Coherent Systems as a company to deal with regardless of where you are in the world.

Thank you Tony.

Coherent Systems sales,service and advice

Tony is highly knowledgeable. I received very good advice regarding purchase of accessories as well as repairs. Not someone who is interested in just shifting boxes. Genuine person. Coherent cables are brilliant. Highly recommended. Thanks ?

John C. Coherent sales and upgrade service

I recently tried the Mutec MC 3+ for a week and really liked what the improvements in sound quality
Tony kept me informed as due to lock-down and Brexit the shipping was delayed. I asked Tony to look at improving the unit so a stage 1 modification was initiated.
It took a few days to hear what the Mutec MC3+ is capable of but even straight away I could hear more depth detail and bass. Very happy with the speedy service and the best thing I can say is listening to music without a ounce of fatigue.

Paul Downs Coherent Sales and service

I have just upgraded my MCRU to Coherent Systems 5D mains cables completing the loom.
The difference they have made has astounded me, there is more of everything, increased weight to the bass, but a lot tighter sound, reducing the boomyiness by a great amount.
Vocals are much more present and clear with a whole extra level of space around them.
Sound stage is enormous and musicality is flowing much more easily.
Great purchase, very happy as always. Tony was as helpful as ever. He’s a great guy to deal with and someone I’d call a good friend, thank you.

Richard Edwards Coherent BD cabling and service

I have been a Coherent customer for a decade and would not think of turning elsewhere. In that time my home audio listening experience has been totally transformed by Coherent products and service. My latest purchase is two BD power cables for my active speakers thus completing an entire BD weave powering my system. The detail and sense of acoustical space is breathtaking. The colour and passion in the music is almost tangible and deeply engrossing. It is almost as good as attending a live music event.
I cannot recommend the expertise and service Tony provides highly enough. Thank you.

Coherent RTZ grounding products, sale and service

I recently had the idea of grounding my audio system and noticed that Coherent audio
were advertising various options and after speaking to Tony Sallis at Coherent, I was advised to try his RTZ(return to Zero) grounding blocks and cables.
But first I wanted to listen to a few more options from Tony's website, such as the Vertex Pico system and he also had a pre-owned Entreq Silver Tellus.

Tony very kindly allowed me to borrow these items over a few weeks so I could get a handle on how they perform, so after hearing the Vertex / Entreq and RTZ systems I was under no illusions what was best for my system.
The Entreq was good in the upper mid and the Vertex good in the Bass but my word the RTZ outstanding in all areas of the audio spectrum, although like all these grounding devices they take a week or two to perform at their best as they need time to dump all of that EMI/RF rubbish thats sitting around in our audio systems distorting the sound.

I have been very pleased with Coherent's going the extra mile type of service and have ended up with a big improvement in sound.

Thank you Tony

Coherent Systems Sales and service

I have been using the services of Coherent Systems (Tony) for a couple of years now.
For the person who wants the best advice and, more importantly, the best sound they can achieve for their budget, I couldn’t recommend them highly enough.

My HiFi system has been transformed with the addition of some Coherent cables, Quadral Galan speakers, Belles Aria integrated amp and then, more recently, a Mutec MC-3 USB digital re-clocker. The last item is simply not the kind of component that I knew existed, let alone realised I just had to have. It typifies why you need a dealer of this experience and knowledge.

If you want to get off the merry-go-round of buying untested mega bargains on Ebay and the like, and actually use your hard earned cash on building a high quality music replay system that really works, then Coherent Systems is a dealer you should try.

Coherent RTZ grounding products
I have a very simple system:
• Nova Fidelity X45
• Belles IA-01
• various Coherent Systems interconnects, speaker and mains cables
that I have bought from Coherent Systems over the years.
I was curious to find out what other improvements I could make to my system and Tony suggested trying out a RTZ grounding box with some grounding cables.
Tony loaned me a RTZ1 ground box plus a plethora of grounding cables (RCA, XLR, USB connectors) to try out.
After a few weeks of demoing the various combinations, I ended up buying a RTZ1 grounding box plus 4 CR3 grounding cables (2 to the Nova Fidelity and 2 to the Belles).
I have a 4K TV. It will display 720p, 1080p and 2160p (4K).
As you step up through the resolutions, more detail becomes apparent and there is a greater sense of realism.
The changes I have experienced (and quite noticeably with the grounding box and cables) in the audio system are along a similar path.
I don’t know if the lower noise floor is solely responsible, but the improvements are all along the lines of:
• more detail
• clearer sound-stage
• naturalness and ease
which all leads to greater involvement with the music.
As an aside, all the above means that I can also enjoy music through the system at low volume levels (if required) as everything is preserved.
Tony’s breadth and knowledge of audio and electronics is quite incredible. He goes beyond the standard approach of simply supplying equipment and digs deeply into the why/how of what makes things tick.
There is no pressure to buy. Simply try it out and make up your own mind whether it works for you or not.
