Hello All, I will be using my Home Theater System in the UK for the first time. I have a Yamaha RX-2080 receiver which can switch from 120v to 240v making it Dual Voltage. However, my Klipsch speakers range from 300-600 watts and they are plugged directly into the receiver for power. I want to ensure that I will not blow my speakers the minute I plug them in and turn up the sound. Can anyone tell me if that would happen? I plan to by a power converter just in case. Thanks in advance! Nelson
