I have not had any problems in the US running a 220 Watt per channel power amp and preamp (designed for 50 Hz 220 V)with a step up transformer.
The current demand will be roughly double what it would normally use at 230 V, which may be higher than is recommended for your home. Check your amperage specifications for your house breaker. Also check what the input power requirements are for the power amp (user manual - how many watts does it consume). Power amps are like toasters or hair driers - they consume oodles of power, so you need to get an appropriately rated transformer and make sure you ground things properly (chassis) to prevent danger of electrocution in the event of malfunction.
Although it worked for me, I would not recommend this approach for saftey reasons. BTW, I have since changed my power amp and got rid of my step up transformer.
