I recently purchased a Yamaha RXV2200 from etronics. Before purchasing I searches locally for some time (Washington, DC area) and came to the conclusion that the next best price was $1099 (as opposed to $848 from etronics) so I decided I'd order from them. Well, I'm happy to say the experience has been very satisfactory so far - it arrived promptly double-boxed. But here is where I have a question for everyone out there: The unit that was shipped to me from etronics was the general unit (not the US & Canada unit). As far as I can tell the only differences are the power cord is not detachable and there is a voltage selector switch on the back. Is this correct? Should I be concerned about this? Other than that the unit is in great shape. I dont think this is worth returning the unit over unless there is a difference in performance. Any advise or insight this group has I'd appriciate. Thanks!
