Time/Process of Hooking up New Equipment

Does anyone else ever felt this way?  My new amp arrived with cables and I want to wait until the weekend to hook it up.  I don't want to rush through it after work when it is dark and I am tired - almost rushing to get through it.  I want to make it a longer event and have time to listen to my existing system, then do the work to hook it up (a bit of a pain) and then rest and have time to listen to the new amp.  Maybe stretch out the fun and be fresh on a Saturday morning.  What is everyone's timing / process for installing new gear and the before and after listening?
