I had a fault on my amplifier, it had a crackle in one channel and I had heard that JS audio was the place to get repaired. I rang John and explained the fault and he was able to diagnose the problem over the phone and gave me a price for the repair immediately.
The amplifier was sent to John to do the repair and while he had the amplifier apart, he contacted me to see if I wanted to do a upgrade at the same time. I was given a choice of upgrades and agreed to upgrade my amplifier. I got the amplifier back and let the amplifier run in for a few hours before I put some music on. Wow the crackle was gone and the music sounded so much more alive with the bass so tight and punchy, what a difference. I’ve been listening to my amplifier for a couple of weeks and I will be sending my amplifier back for the full monty upgrade which John assures me I will still have a further surprise after the next upgrade. I can’t wait to get it done, I have met John in person and he is a genuine person, I don’t think I would let anyone else touch my equipment. I fully recommend John and I’m happy to be contacted if you want a reference to his work.
