Default power amp( arcam)

I have a p1000 power amp by arcam and it is buzzing/humming from the transformer. I have measured my vaults im my mains and it seems pretty constant of 247volts. Is this a little high? I believe that the amp is designed for 230v or that's what it states near the input connecton (iec), if it is high can my local provider reduce it? I beleive this is the problem as my r80 spot bulbs blow regulary as well. Thanks, any advice is greatful.
