It's not better for the amp. It's not worse, either, it just doesn't matter to the amp as long as it's set up for the same levels that you're giving it. The SQ can be better; with a larger amplitude input, the effects of any interference you might be getting would be less, lowering the noise floor. If you don't have interference issues, it's not going to matter at all.
