DAC Upgrade

Sorry that it has taken so long to get this testimonial up, following an excellent repair job in July. My cherished DAC had died and so I contacted John to discuss getting it fixed. John set out the options and I decided to have it upgraded. The result was superb: better defined bass, a huge […]

CD & Amp Upgrade

My father and I have been hifi enthusiasts for years visiting the hifi shows and listing to the mega bucks systems, I first found out about John whilst searching online for someone to fix my fathers Musical Fidelity Nuvista M3 amplifier, after reading all the good press John has I pointed my father in his […]

CD repair and upgrade

Hopefully audiophiles are driven by the desire to get closer to the recorded music when they upgrade equipment. Sometimes these new purchases are significant and the difference is immediately audible. I recall the joy of realising that NAD could do something with amplifiers that Clive Sinclair couldn’t; that a Gyrodec got more from vinyl than […]

CD Repair

The Power Supply Caps in this Player were found to be in poor condition and John replaced them with Mundorfs. Before I bought this player, I read the review by Roy Gregory who gave it the thumbs up. However, his only significant criticism related to a softness in the bass when compared to the very […]

follow up upgrades

After having my X-P100 pre-amp updated by John- (testimonial Jan 8 2014 MF’s loss) I contacted John and consulted him about a heavy thump coming from my left hand speaker, if I ever had any reason to switch the amplifiers off and on again. He advised me to have my amps looked at a.s.a.p., so, […]

Exceptional improvement.

The moment the amp was switched on, I was totally surprised with the sound, not only it sound completely different but totally fantastic. The sound stage is so much wider now and airy that you do not actually know that the sound is coming out from the speakers in front of you. The sound was […]

Exceptional Service

Really lost for words….the upgrades to my X-A50 mono blocks and X-P100 have resulted in a stunning overall improvement in clarity, definition and musical ‘naturalness’. The originals were fine indeed but John’s interventions have taken this sweet little trio into a different league. Wonderful guy to deal with also….! Highly recommended.

Musical Fidelity XAS100

Incredible. Don’t sell your classic Musical Fidelity separates. Send them to JS, you will well impressed with the results. I was thinking of selling to upgrade. I have definitely re considered after hearing the difference and will be supplying JS with more work in the future.
