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?  


I just brought home an amplifier from the shop tonight. It's about 52 degrees outside. 70 in the house. I'll hook the amp up tomorrow. Condensation can fry things in a heartbeat. I take no chances and wait a day.

@toddsyr Giving components time to settle part of my reasoning for generally waiting until at least next day for first listening. Shipping and temperature certainly affect precision parts.

Today I pickedup my new audio ethernet swtich and linear power supply on the way home from my 5 hour hike this morning (13.5 miles).  I showered and drank some liquids before I installed it--30 minute delay.  was listening in 45 minutes from the time I walked in the door.
