No sound difference. How can I state that?
Open your Windows calculator (or Mac, or Linux).
Type 750 / 500. You get 1.5 right? Now press the "log" button, you get 0.17.
Now press * 10 - you get 1.7. There is 1.7 dB difference between those two amps. A level that you'll go "I think I hear it"... Get to 3 dB and you'll know there's a volume difference, but it won't be much. Get to 8 to 10 dB and you'll hear it as twice as loud.
Bottom line, unless you're talking about a ratio of 2 or more in terms of power, it's really not an issue. Go with the smaller amp (you'll have the same sonics), save the cash, space, weight, and power draw.
