I recently brought a vintage (30 year + old) Pioneer class-A power amp in to Pyramid Audio for repair. Considering the age of the unit and scarcity of factory parts, I was surprised and delighted that they were able to restore the unit to better-than-new specifications, and at such a reasonable cost and turnaround time. I wouldn't hesitate to recommend them.
Pros: Courteous service, good turnaround time and reasonable cost.
Cons: None I can think of.
