Astonishing
In the audiophile world we talk about the law of diminishing returns; increasing investment for a marginal gain. When my MF A1000 came back from John there was nothing marginal about it. As soon as we powered it up for the first time the difference was astounding. I thought I already had a great amp […]
Craftmanship
“I admire the engineering skills and craftsmanship almost as much as I admire the sound of the Upgraded Graaf. It takes great skill knowledge and knowhow to do an upgrade on a piece of equipment. You can go to far and totally destroy the sound you loved so much. Having Knowledge and understanding of component’s […]
A300
Recently had JS Audio do a stage 2 upgrade on my 17 year old A300 integrated amplifier and the results are very impressive. Initially it sounded much more dynamic with far more detail and control and as it has run in continues to get better and better. It has brought to life a 3 way […]
MF X-Ray 24bit CD full upgrade – worth every penny!
My CD player had developed a fault that was tripping the mains. I discovered JS Audio repairs by searching for my fault, and gave John a ring. It is such a good CD player I opted for the full refurb/upgrade. Now I’ve been playing the renewed player for a couple of months, all I can […]
Excellent service and upgrade.
What can I say, this (previously tired) old amp sounds much better than I can ever remember. Better control at the bottom end, and the overall clarity and projection is stunning. I know John was impressed with the upgrade suffice to say I’m amazed at the transformation. I can’t recommend Johns upgrade and repair service […]

Amazing service and Upgrade!
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!” […]
Musical Fidelity X-series upgrades
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 […]
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 […]
