Why noise reduction? The second is very heavily compressed, the first cleaner. What EQ did you use in the end? Personally it sounds very radio compressed now – so it is LOUD – all through, including bits that should perhaps be quieter. All your versions sound different, but not really better? You are treating it like an error being concealed when you just need a bit of eq and maybe a little compression – you seem to just pull settings out of the ether?
