Amazing Transformation
I have had my amplifier from new, so over 20 years. The input selector had been playing up for some time, but not only that, it had begun to sound lacklustre. Only one thing for it. I spoke to John, who explained my problems were common for the age of the amplifier. He explained about […]
Audio Magician
Bought used around 15 years ago, my amp of maybe 25 yrs had started to hiss and crackle. John took it in to look over, diagnosis worn out. Got it back this weekend, totally transformed! Immediately sounded impressive, now after only 15 hours of the recommended 30-40 running in it sounds fantastic. Much greater depth, […]
You Work Out the Maths!
So, after many years of owning the Nu Vistas, the long dormant upgrade bug was kicking in and off I went to a local respected Hi-Fi shop to see and hear the latest offerings. As soon as the store knew what I had, the staff nearly screamed at me to keep the Nu Vistas and […]
Transformed Amp
The latest upgrade from JS Audio is to my KW750 power amp and was a Stage 1 plus WBT terminals plus 1kW Audio Grade transformers. Now that the amp has had some time to “run-in” the difference is substantial with improved dynamics, transparency and clarity. Sound stage is bigger and better defined and music just […]
A3CR Pre and Power Amplifiers
I have owned my amps for 20 years and love the MF sound. I was considering purchasing the new M6 pre/power but after several exchanges with John, elected to get mine rebuilt and upgraded. They have been running a couple of months now, together with a new Rega P10 and all I can say is […]
Nu Vista 3D CR CD Player upgrade
JS Audio previously upgraded my MF A300 amp that still sounds fantastic so had John do a Stage 2 upgrade on my CD Player including new valves. Initially It sounded better and had greater detail but 4 months on and time to run in the improvement is another level. The separation of instruments, soundstage, detail […]
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 […]
