PS Audio BHK mono擴大機

Instead of paralleling just the outputs and managing the feedback problem I previously described, he fashioned an entirely new topology that pairs every component, not just the outputs. So, for example, the input vacuum tubes are tied together acting as one. This is a technique I have seen used only in moving coil preamplifiers to lower noise. Many moving coil phono preamplifiers parallel multiple devices (usually transistors) together. Each time a new device is added, the noise floor drops. So, for example, adding one device in parallel drops the noise in half. But getting another such drop requires two more in parallel, then four more, then eight more and so on. But noise was not the main goal in BHK’s thinking, as the noise level of the amplifier is already extraordinarily low. Rather, sound quality was foremost on Bascom’s mind when pairing tubes, drivers and outputs together in a configuration new to power amplifiers.

嗯...為何？

二個零件不可能特性完全相同，多了路徑，訊號必然有時間差，聲音應該比較糊吧...
