Musical Fidelity P170 Power Amplifier
Knowing the other repairer like the Getitfixed which they destroyed this power amp when they returned it to me. Thankfully AudioJSRepairs which is Mr John to the rescue! Mr John completely remodified and improved this power amp significantly. I am listening now and to my surprised, the details, botom end to mid and highs expanded […]
Repair/upgrade
Great job. My vinyl has taken a farther step on the way to perfection. Highly recommended service, glad I decided to send my amplifier (musical fidelity A3.2cr dual mono) for repair and stage one upgrade.
Transformed Goldmund
John has just completed a startlingly successful repair and upgrade on my classic and much sought-after Goldmund Mimesis 9. It is now able once more to run rings around current power amp references. I have nothing but praise for his work and technical insight; you can safely leave your beloved high-end gear in his hands, […]
Nu Vista 800
It’s been a year now since getting my NV 08 repaired and upgraded to stage two. I’ve deliberately given the amp plenty of time to settle in as I did now want to give a “false” report. My initial impressions were not that great to be honest . Yes , the amp certainly was better […]
Musical Fidelity M6Si
Just want to share my opinion with the upgrade of my amp – Musical Fidelity M6Si. First of all – John Sampson is a brilliant tech-guy, he knows the MF products in details and knows their weakness. After contacting John we clarified the upgrade – 10-15 emails and I decide to make upgrade Stage 3. […]
More musical
I got in touch with John for repair of my CD player which had stopped providing an audio output and decided to go for the Stage 1 upgrade at the same time. I’m very pleased with the improvement in sound quality. Although I’ve long appreciated the Musical Fidelity sound, the combination with my PMC speakers […]
Bought back to life
John is an ex MF service engineer, I worked for the company during the latter years and I’ve always been a fan of MF kit. With the sale of the company I was unsure how legacy products could be serviced and repaired. I knew of John’s work and how highly regarded his work is seen. […]
Musical Fidelity NuVista 800
Upgrade done in an extremely professional manner. All Capacitors replaced op-amps internal cabling and speaker binding posts replaced. The first thing I noticed was that the sound is so much smoother; sounding much more like a single ended amplifier. The smoother sound is not at the expense of information; far from it. I can now […]
A5 CD and A5CR pre
John completed a Stage 2 upgrade on my A5 CR Pre, I was using a Croft Micro 25R pre, sounded good but presented a vague and inconsistent soundstage. John assured my that the upgraded pre would bring everything into focus.. he was SO right. Next stage was to upgrade my aging A5 CD to Stage […]
Musical Fidelity Fully Balanced Pre
You switch on the amp you’ve cherished for 11 years and after a moment it turns off and you have that sinking feeling. You take it to the local highly respected repairers and you are told that the main transformer has failed and they cannot get a replacement. You then dredge from the back of […]
