Item Repaired/upgraded: Musical Fidelity A5 CR Power Amplifier 

My Musical Fidelity A5 CR Power Amplifier one day went "Pop!!!" and smoke started emitting from the unit! and tripped all the electric out in my house! I stupidly took the unit to a local repair guy (who has a shop!!!) who diagnosed fault as "Tordial Transformer gone, cant get parts, could maybe make one!" A costly lesson for me, he had taken the transformer out cutting it from the circuit board and unwrapping it! I then found John online and he rang back straight away. Even though John did not have the unit he seemed to know several things it would be straight away and said it was very unlikely to be the transformer. After reading the testimonials I decided to send the unit to John. Next day John called with a full diagnostic, quote and service/upgrades available with no hard sell, just professional information about what it may improve. I decided on full service/upgrade. 10 days later I had the unit back on my rack and looking like new! now that's service! I've left reviewing for several weeks as the sound has took a while to settle and has sounded better every day. Sound improvement from Johns expertise are a much larger than any upgrade Ii have added to my gear for less cost. Now just so musical, 3-D soundstage that is so detailed and lifelike it is quite spooky on certain records! The power, tightness and tunefulness of the bass and the depth of soundstage are massively improved. At times I feel like the bass goes through the floor, and I have my speakers spikes on concrete plinths! John Sampson Is a professional that obviously cares about his customers' and their hi-fi units and can service your components to function at their optimum (not held back by corners cut in manufacturing costs). I would have absolutely no hesitation in recommending John and am considering sending future units to him when funds allow! Go for it - you will not regret it!


Musical Fidelity X-series upgrades

Item Repaired/upgraded: Musical Fidelity X-T100 amp / X-Ray v8 cd player 

My Musical Fidelity X-T100 amp had developed a couple of issues - interference on one of the speaker outputs and a sometimes unresponsive channel select button. I wanted to get the unit repaired and having spoken to John I decided that it made sense to go for an upgrade at the same time.

John had already upgraded my matching X-Ray v8 series cd player a while back with great results, therefore I had no doubts about going ahead with the amplifier too.

I have had the unit back a few weeks now and I have to say I am stunned at how good it sounds. It would be very easy to be sceptical or put upgrades down to how it sounds to the listener's ear. But honestly the upgrade has really transformed the sound quality. These units always sounded good, but when listening now it's like chalk and cheese. The overall sound stage and depth of sound makes it a real pleasure to listen to. You can hear every detail and follow each instrument / voice as if they have been separated out and are performing live. The sound is far less cluttered and can be enjoyed at any volume. I have really achieved what I wanted - a superb sending little setup at a relatively modest cost.

My advice if you're considering an upgrade... go for it, you will be impressed, the detail is amazing !

My thanks to John for his expertise.

Item Repaired/upgraded: Studio T 

My 30 year old Studio T power amplifier developed an intermittent fault which proved difficult to nail down. Although the amp played well most of the time, John identified some instability and recommended a partial rebuild, at a very reasonable price. That work has now been done and has cured the fault while also improving the sound quality. I'm happy to recommend JS Audio, and will be putting more work John's way when funds permit.

Item Repaired/upgraded: A308 amplifier repair and upgrade 

If you care to read any of the glowing testamonials please note these people are not exaggerating. I had my A308 amp upgraded in February and the results are spectacular, I'm not going to go into any detail, other testimonials will explain improvements more eloquently than I. I plan to have my A308 CD player upgraded by John soon
