M3 Nu Vista Amp
Thanks John. The amp sounds so much better now. And I appreciate too your recommendation for the turntable and for upgrading the phono stage in preparation. Now enjoying all my old vinyl - puts CDs to shame.
Power Amplifier upgrade
5 years ago John upgraded the capacitors in my amps to help them drive my Thiel 2.4 speakers, the improvement was amazing. John has recently completed the final stage upgrade by replacing the transformers and adding even more capacitors. The impact has been transformational. They sound so much more powerful, I have depths of bass I could not ever imaging from the Thiels and so much more detail. The amps, which also used to heat the room are now cold in operation so I assume are far more efficient. I can't recommend John's upgrade service highly enough.
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
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.
Delighted with the difference A308
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.
