I am looking at buying a BeoSound 9000 CD unit, however, it is a European model 220 volts. My question is can I connect my current 120 volt (Penta) speakers up to this system? Will I get any feeback due to the voltage difference? Also can someone clarify if a model 2571 is a MKII or MKIII. In the product info section it shows MKIII as 2572 and above.

 Thanks

Ron
