It’s been some weeks since John performed the repair and upgrades to my Musical Fidelity A300cr Power Amplifier. Upgrading the power transformers has given the amplifier much more control and muscular grip over the music. One thing I noted in particular was the extra bass extension which is apparent. The sound stage has opened up and more expansive. John has certainly injected more life into this amplifier. On another note, the unit was returned in great condition ‚Äì it is always a relief to know that one’s hi-fi is well looked after and in good hands while it is away from home. It goes without saying that I would happily use this service again.
