I received an upgrade and repair to my Musical Fidelity A3 Integrated Amplifier in November 2014. As my husband accidentally broke the speaker terminal, I searched online for a repair specialist, and that’s when I came across this site. When reading the testimonials I decided that an upgrade would also be the way to go. Since buying the A3 Integrated Amp & A3 CD player with Monitor Audio G20 Speakers I felt the sound just wasn’t as good as I had expected. I contacted John who advised on the cost of repairs and an upgrade. When I received it back I couldn’t wait to listen to it and boy was I impressed. I noticed a difference straight away which was a pleasant surprise. The sound was much richer and deeper and with a very punchy base and it has improved greatly since then. I’m a very happy lady and revel in the delight of listening to my cd collection each and every time I play it. My husband is so jealous that he is going to get his hi fi upgraded also. Thank you John for your expertise and for enhancing my music life.
