I thought I'd post the latest info regarding my initial 'transcontinental electrical dilemma' . . . anyway, in addition to hearing from Emotiva, I received a reply from both Denon & Samsung. This was Denon's emailed reply to my inquiry:
"Regarding your question, as long as the electrical in the home supports 120V, then it's safe to use the 4311 there. A 50 or 60 Hz cycle won't have an effect on the receiver."
As far as Samsung goes, I couldn't get them to reply to my emails to save my life; however, I spoke w/ Samsung tech reps (on two occasions) and they assured me that the cycle rate wouldn't 'likely' affect the TV . . . additionally, they referred to an internal circuit breaker that would be tripped before any damage would be done (one said that was the worst case scenario). . . I was told that 'likely' was the most definitive response they could give . . . (((Excuse the personal rant; but it's beyond me that a global company like Samsung would produce a higher end model, like the 8000 series, TV that isn't dual voltage . . . I have two lower end Sony TVs and both are dual voltage . . . anyway, go figure))).
In any case, I just wanted to post a follow-up in case anyone else would be in this situation . . .
