Pioneer Quantifies Class D Power Savings

To dramatize the efficiency of its two Class D receiver models, Pioneer hooked up one of them to a meter that monitored power consumption in real time as compared to a Class AB model. At left is the Class D SC-57. At right is the Class AB VSX-1021-K. Though rated for more watts, the SC-57 sucked up less power. Pioneer also showed three new Blu-ray players ranging from $199-399 and made a point of saying they are built to last, unlike all too frequently disposable competitors.
