Mark Hodkinson Coherent Cabling, RTZ grounding systems and service

I contacted Tony, as I felt something was missing from my system… music !!

Having been living with Entreq cabling plus was also not happy with the large Entreq boxes and the amount of cables for grounding everything,
Decided to remove all the Entreq from my system I spoke to Tony about the way to go and my budget, a way forward was decided,
Tony arranged for 6D mains cable, 6d+ AES interconnect and 5D Speaker cable to be sent for evaluation in my system.
After a few days the system really started to open up. Over the next 2 weeks, the system was more dynamic, spacious and musical,
It was a total contrast to the lack lustre presentation of the Entreq kit.

It was decided to try one of Tony’s RTZ boxes and connections, had to wait a little while for Tony and his guys to make a new RTZ 2 mk2grounding box as they are all made in house, to Tony secret design. The RTZ 2 mk2 arrived with 5 ground cables (3 RTZ C1 & 2 RTZ C2), I connected the CD player first, and the changes started immediately, more separation, depth and dynamics. Next was the DAC board in my Amp, again more of the same. Then came the 2 connections to the Amp, wow that was a massive improvement. Finally the Streamer, all provided positive upgrade to the sound…..fast forward 2-3 weeks later and I swear that its still improving, the sound from my system is so much more enjoyable, and I’m back to listening to music not my system, and loving every minute of it.
The other great outcome is I have gone from 4 large Entreq boxes to one small half width discrete box, which outperforms all the others.

Dear Tony

Firstly, apologies for the extreme lateness of providing written feedback.

As you will recall, I was interested in the Mutec MC-3+ Smart clock USB, you had a demonstration device, and a loan was quickly arranged.

I imagine some people may be put off by the display, they shouldn’t be. The reality is that it is very easy to set up.

The first album I listened to was a poor recording. I wasn’t expecting overly much. However, even from cold a difference was immediately apparent. More albums followed, always with the same beneficial result. But, and let’s face it there’s always a but, the music got better and better.

For me, the best way I can describe it is that with the Mutec in situ, the music snapped into focus. It was easier to pick out and follow the various instruments and rhythms. Listening was so much more rewarding.

For me, the key test for any new piece of equipment is how does my system sound without it? Will I still be able listen to it? Well for me the answer was that my system was the poorer without it. Obviously I could still listen but it was significantly less rewarding. So I bought the Mutec and have not regretted it. My only regret is I should have bought one sooner.

Note that I tried the Mutec MC-3+ Smart clock USB interfaced between CD player, CD transport and a music server and a variety of DACs. Whichever combination was used, the Mutec always improved my listening experience.

Many thanks for all your help and advice. I really appreciate it.

Nigel Lester Coherent Systems 4D speaker cable and interconnect cables and service

Hi Tony,

What can I say, the transformation of my system is quite remarkable. I had been listening to some pieces of music for 50 years BUT I’ve never heard them like this before!!. Other than the bigger and deeper sound-stage and instrument separation It’s the shear musicality that is impressive. As you can tell I am very impressed, their great Tony.

Regards Nigel

Coherent Systems Cables Sales and Service

After contacting Tony for some advice regarding my long term system, Initially I tried some 6D speaker cable which I found to bring a greater sense of speed and transparency to the sound but it still wasn’t where I wanted it to be.

Tony was then kind enough to provide a balanced 6D interconnect and two power leads which instantly took everything to a level of musical enjoyment which I didn’t think the system was capable of. Swapping individual cables in an out only served to prove that the musical sum of the whole is indeed greater than the parts.

Coherent Systems, Service, Upgrades and sales

Coherent Systems came to the rescue when my Bel Canto Pre3 VBS needed a new power supply. A QP1 with a 4D d.c power cable specially terminated for the Pre3 was quickly supplied and was soon doing the business.
It is obvious Tony has lots of experience with the Bel Canto brand and soon discussions turned to improving the Pre 3.

The Pre3 was duly fully overhauled and certain critical components improved what was already the best solid state per-amplifier I have heard was taken to new levels. There was a noticeable increase in the detail you could hear but without any added artificial brightness to the sound.
Some 4D xlr cables were soon added and they proved to be the icing on the cake
Overall a great experience from Tony and the team.

Matthew Randall Belcanto Pre 3 servicing and upgrades

Recently had my somewhat poorly Bel Canto Pre3 pre amp serviced & tweaked by Tony & his team.
It’s been back in my system for a couple of weeks now & it’s definitely a WOW from me. It’s now sounding so much better in all areas...... cleaner, more linear, better separation bass detail & cymbals are sounding like cymbals again rather than the dustbin lids.

Tony’s communication throughout the process was first class.
I will definitely trust my Bel Canto DAC to Tony for work in the future. I would wholeheartedly recommend Tony & his team to anyone thinking of getting advice, work, or purchasing equipment from his portfolio.

Many thanks from a very satisfied customer, Matt.

Martin Schroder: Hovland HP 100 Pre-amplifier overhaul and upgrade

I contacted Coherent Systems by email out of the blue regarding a 20 year old Hovland Pre Amp that had some faults and issues that required technical electronic expertise to resolve.

I had not met or been in touch with Tony previously, but he was very welcoming and gave a clear timeline to investigate the issues. Once he had looked at the unit he detailed possible actions and associated costs, but with an emphasis on retaining the natural sound of the amplifier.

The amp was subsequently overhauled, capacitors replaced and a new stepped attenuator installed. The sound is very much improved, much more detailed with a wider and deeper sound-stage. We are very pleased with the outcome and It is absolutely obvious that Tony knows what he is doing! I am now in discussion with him over a pair of power amps.

Coherent 6D Xlr balanced analogue cables and service

Paul Hudson Coherent 6D Xlr analogue cable and service 23/3/31

Thank you for the cables they came earlier than expected; as you predicted it might.
So I have had a fun weekend listening. I'm actually surprised by the amount of improvement which has resulted from swapping just one balanced cable, which was already a quality item.
The music is now more holographic, fluid and richer sounding. Plus there is a much more natural purity to the high frequencies which now seem to hang in the air when a note has finished, a little approaching like which occurs a concert. I've never had this in a system before. I am looking forward to completing the set and getting coherent cables right the way through.
