Musical Fidelity

Item Repaired/upgraded: MF A3.2CR Integrated 

Yet another purchase off Ebay, with a noisy volume, not just noisy when the volume was touched, but extremely LOUD cracks through the speakers. Spoke with John about a repair initially and dropped the amp into his workshop, socially distanced and masked of course.
Spoke again with John as to the problem and was given a cost to repair, but decided to have the A3.2 upgraded and I am so glad that I made that decision.
The amp sounds superb even during its running in period.

Great service from John, many thanks


Power amp rebuild

Item Repaired/upgraded: Meridian 557 

A bit late with this review. A couple of years back I purchased a Meridian 557on Ebay for a reasonable price as there was an intermittent fault on one channel. When I ran the amp there was a variation between channels and so I searched for a specialist to repair the amp. Meridian did not want to know (seems to be a typical problem), so searching the web produced JSAudio as a go to. Spoke with John who detailed the problem I was seeing and what should be done to bring the amp up to date. Duly dropped the 557 into John's workshop for its complete rebuild and update.
When the amp was completed, it was duly plugged into my system and kept live for a week to "bed in". The results of John's work were astounding, the amp sounded so superb, no distortion, just beautiful sound, with LOTS of power.
Thanks John


Delighted with the difference A308

Item Repaired/upgraded: Musical Fidelity A308 Integrated 

I have been a audio enthusiast for about 10 years, as perhaps most chasing a sound that I am happy with. Plenty of speaker amplifier combinations have come and gone. My musical fidelity A308 Integrated came the closest but after John working his magic on my amplifier with his upgrade service the difference it has made has I believe got me to the place I have been chasing. I was shocked at the difference it has made to the same amplifier. Thank you John.

Item Repaired/upgraded: Elektra e100 

My 20 year old Elektra e100 was half dead with one channel completely gone and horrible static buildups and spiking threatening speaker safety, the amp was in desperate need of saving. My local MF repair company (local being within 50 miles) held on to it for over a year and was not able to fix it. I finally got it back and then found John at JS Audio Repairs. With John\'s history of working with Musical Fidelity devices, it was a job that was no problem for him. And just 10 weeks later and my amp is back now looking and sounding better than it ever did. I chose to have a complete refurb of the amp that cost me a less than I had been fearing and so wow, great job done, thank you John and to anyone reading this testimonial, I can only offer a big thumbs up from a very happy customer. Good job John. Thank you for your work and efforts sourcing the difficult to get hold of parts...


MUSE Model 300 repair & upgrade

Item Repaired/upgraded: MUSE Electronics Model 300 mono block amplifiers 

So glad I found John who was able to advise on repair and upgrade options for these old amps, they've been repaired twice before so I wanted to make sure they stand the test of time. Decided to go the whole hog which entailed:
- upgrading the toroidal transformers from 500VA to 1000VA (custom built and main cause for the delay)
- upgrading the smoothing caps from 4x10,000uF to 4x22,000uF in each amp
- upgraded the MOSEFETs to higher voltage modern Profusion devices ECF10N/P20s (6 pairs each amp)
- new binding posts, internal cabling replaced and sorted.

After many months with work delayed due to COVID impact on suppliers, they're back home. Its clear there is a LOT more dynamic range, lower noise floor, more details coming through, timbre of drums is richer etc. And the bass - I've never heard bass so deep and controlled before on my system. The overall signature from my ATC SCM40s is anything but lean - the amps now really show what these speakers can do and I expect they would drive the bigger SCM50s well. The original character of the amps (or lack therefore) is retained but with a lot more of everything.
While not cheap, the cost has been a great investment and I hope these amps will last many years to come, I am thoroughly enjoying them.
Thank you John!
