"I recently managed to knock my NAGRA CDC CD player off the top of its equipment rack. After initial investigations on what to do, I was pointed in the direction of Anthony Sallis of Coherent Systems who manage servicing and repair on behalf of Padood who distribute Nagra in the UK. The machine was dropped off at Coherent Systems on a Saturday morning where we also listened to a very enjoyable state-of-the-art yet affordable system that Tony was playing. Early the following week Tony phoned with an assessment of what could be done, and by the Thursday the work was complete and the Nagra was being soak tested after having been repaired, cleaned and serviced. The standard of the work and the attention to detail at Coherent Systems is absolutely first-rate. What could have been a costly repair bill simply wasn't, the rates for the work were very reasonable, couple that with friendly, professional service in a welcoming location and you have easy to recommend service.

Yes I'm delighted with the speaker leads performance, they have certainly "filled out" during the time I've had them. One thing that has surprised me is their musicality but not at the expense of detail. Certainly an excellent match with the Avalon / Vitus as you said they would be. The extra length has allowed me to get near perfect positioning and the high ceiling in our barn conversion has also aided an all round improvement. My system is in a place I didn't think possible, you have played a significant part in that.

It’s a refreshing change these days to phone a company in search of a quotation and instead find yourself talking to someone who is very obviously knowledgable and passionate about their line of business. Tony Sallis is just such an individual. I first contacted Coherent Systems to enquire about a factory upgrade to the motor for a Mk I Oracle Delphi, but our conversation flew off on several interesting tangents and it became apparent that audio equipment and music is much more than just Tony’s day job. After our chat, Tony promptly emailed me with a set of options for my motor upgrade, including the use of some perfectly serviceable parts that had previously been removed from other Delphis (a Mk III and a Mk V) during their upgrades. A deal was struck for what I consider a very reasonable price, and the required parts arrived the next day, just as Tony had described them, and extremely well packed. So far, so good; 10/10 for customer service, but the story doesn’t end there. How many other hifi specialists are happy to field dumb questions via telephone in the evening, a couple of hours after closing time? And how many are happy to sit on the end of a phone with a power supply and multimeter, describing the pinout to a perplexed customer? Not many, I’m guessing. However Tony is just such a specialist, and well worth seeking out. The kind of kit Coherent Systems deal in is not cheap, but whether you’re looking to spend a considerable sum on upgrades, or whether you’re simply looking for some basic maintenance essentials and advice, you’ll be greeted by the same combination of dedication, enthusiasm, and professionalism.
