Nice question. I am just wondering if anyone will disclose their current killer acquisition hacks. Moreover, the question heavily depends on your business, so is it B2B, B2C, online, app, bot, etc.?
However, a good read on this which tackles all ways of user acquisition/Marketing is 'Traction' from the DuckDuckGo founder. It's not an exciting book but gives an ok overview.
You could also just start with the channel which seems most obvious, set up analytics from day one and iterate over and over. With this approach you should get a good feeling if your acquisition strategy works and if yes you should optimize. Otherwise move on to the next channel.
Edit: When you search for Traction on Amazon.com there's also another one on #1 (good Amazon search hack from another other author btw) which is not the mentioned book (the one I mean is blue-ish)
