I sent John my M6si when the power supply blew, and am so glad to have found him. The whole process was swift and seamless. Within a week of sending my amp in it was on its way back to me after John had not only repaired but also upgraded the power supply. To be honest I hadn’t expected, even considered, the improvement in sound that would result, but from the very first track I put on, Stehl Auf by Ellen Allien, it was plain John had worked wonders.
In this day and age it is refreshing to find a business that simply and without fuss, just does the job and does it well.
