Hi Tom, I really enjoyed reading" logitech Z-2300 , last of the titans." I didn't realize how lucky I am to have one of these. Problem is I am moving to Sweden where the power is 230volts. My Z2300 is rated at 120. I really want to use it over there. Can I just buy a new power supply and install it? How easy is that, and where to get a power supply that would do it? I'm hoping you sell one, and can show me how to switch out. Lot to ask I know, but I really like these speakers.
Yes, another brand would work just fine, as long as the voltage, milliamps, and tip (positive, or negative assuming it's a standard round plug) You can find all of that information on your existing PS brick.
I would always recommend exhausting all options in finding one built by your manufacturer. The other thing you can buy, is a travel power convertor. That could get cost prohibitive though, they are not cheap.
