Rel Sub Loss of Sound

Great repair. Not an easy fault to find but John stuck with it to find the issue and eventually found it. Highly recommend his services.

Pioneer Receiver SX-980 lives on

Many thanks John for your excellent work on my 1979 Pioneer SX-980 Receiver. The Pioneer had begun to show it’s age and over time you don’t really notice the slow degradation in the sound. Along with some repairs and fixes required I was in two minds about what to do, buy new or refurbish the […]

Amazing

I previously owned a Musical Fidelity M6i Amplifier and this was good but after a few years the upgrade bug bit so I contacted John for advise on which Amplifier I should buy with a view to it being “the last Amplifier I would ever need to buy” John advised me to try and get […]

Musical Fidelity KW500

I had a fault on my amplifier, it had a crackle in one channel and I had heard that JS audio was the place to get repaired. I rang John and explained the fault and he was able to diagnose the problem over the phone and gave me a price for the repair immediately. The […]

Upgrade to NuVistya3D & kW550

I now know what those guys were going on about in HiFi+ so many years ago. Following a bit of to and fro I installed the upgraded kit and was reasonably impressed. But it didn’t blow me away. However, some months later now that it seems run in, yes I’m blown away. I could go […]

The depth of sound, seperation and clarity are all amazing. I never bother with reviews normally. I am now very tempted to […]

Simply The Best

I received an upgrade and repair to my Musical Fidelity A3 Integrated Amplifier in November 2014. As my husband accidentally broke the speaker terminal, I searched online for a repair specialist, and that’s when I came across this site. When reading the testimonials I decided that an upgrade would also be the way to go. […]

FANTASTIC UPGRADE

About 1.5 year ago I had my MF NuVista M3 amp repaired for the ‘source selector issue’ by a well known audio repair shop in the Netherlands. After 6 months the problem had returned. John told me he would be able to solve the issue and I decided to go for it and also upgrade […]

Simply Astonished !

I have always been extremely happy with the sound of my amplifier and as a reviewer (www.hifipig.com) I regularly come across many alternatives. However, when my amp dropped a channel I needed a repair fairly quickly and by someone I had full faith in. I had heard of John’s work but never had the need […]
