Why High Plate Voltage in 2A3 AMP?


Most of the designs I have seen, the plate voltage is about 300-320. However, I have seen few others that have plate voltage as high as 395.

This exceed the tube specification.
What is the pro/con of high plate voltage. My thinking is that it will kill the tube sooner.

The reason you see 300B preamps and not 2A3 preamps, is that low voltage gain is considered optimum for a good preamp...?
