I apologise for asking a question that many have been asked before but I can't fins it on the forum search. Is it safe to assume the DAC+ will work with the A+ as well as the B+?
Not only does it work but you can take a micro sd card from a B+ and it will work as well. I don't like to boot into a desktop with a Pi and prefer to do all command line stuff which leaves you in a predicament with the A+. No ethernet and unless you hook to a USB hub with monitor, keyboard, wifi, and mouse you aren't configuring wifi.
If you have another Pi, configure your OS with Wi-Fi then just slap the micro sd card in your A+.
