John Sampson to the rescue!
We had our Nu-Vista M3 ‘Fine Tuned’ by Musical Fidelity a couple of years ago. However the channel selector became completely degraded and we contacted John to ask him to repair it and, in for a penny in for a pound, went for a general upgrade as well. What I didn’t really expect was for […]
Repair/upgrade
As with many audiophiles of my age a lot of kit has passed through these hands in an attempt to get what are usually small improvements in sound quality – often no improvement at all just a different presentation. In my youth I lusted after Sonus Faber speakers and when a pair of Guarneri Mementos […]
Nu Vista M3
I have had this amp playing now for a few months after the upgrade and i have to say i am very pleased .The overall presentation is much more natural sounding and the base is just so tight its amazing.I get the feeling that i am hearing into the music much much more and the […]
Tri-Vista 300 Upgrade
This was a heavy and expensive amp to ship to the UK from Canada for John to work on! It was worth the effort and cost though as the amp came back a better sounding unit compared to the original product. I always liked the Tri-Vista but it has been sitting in my second system. […]
MF KW Kit upgrade
I have been meaning to write this review for the past three years as john upgraded my full suite of Musical Fidelity KW gear. The result even three ears later still blows people away. Subsequent to to the upgrades I moved to Kenya and managed to damage the Power Amp due to crap power out […]
A3CR/A5CR Amps Upgrade
I sent my Musical Fidelity A5CR Pre Amp and pair of 10 year old A3CR Power Amps to join for his upgrade including terminal replacement expecting a small improvement (I’m a bit cynical due to the endless exaggeration when it comes to audio on the internet) but hoping to be pleasantly surprised. The difference was […]

Musical Fidelity F16 Power amp reincarnated
I bought this amp new many years ago, partnered with a MF F25 preamp. JS Audio transformed the F25 bringing improved timing and clarity , the bass although clearly tighter was let down by the power amp which was too ‘loose’ .I then bought the Gryphon Diablo a superb integrated and currently about £10k retail […]
New lease of life for my A3 amp
I’ve had my A3 power amp for some years and it occurred to me that replacing it to a similar standard, if ever that became necessary, would be costly. After seeing so many positive reviws of John’s work it seemed a safe bet to have him overhaul and upgrade my amp; I was not disappointed. […]
Musical Fidelity X-CAN v2
II purchased a used X-CAN v2 headphone amp, which turned out to be very sub standard. I contacted John and he recommended a full upgrade spec.After a couple of weeks amp was returned in tip top condition. the resulting sound quality in terms of detail and tone is quite superb,the service and communication from John […]
