If you listen at or arround 70db any speaker of your choice and not too late including typical dynamic full range, you'll be OK. I live in the apartment and none complained yet of my Aerial 10's powered by sunfire amp.
On weekends I sometimes crank it to 90dB and on weekdays music is only heard till 8:30pm. After that I don't want to disturb my macaw at his sleeping time otherwise 60dB is still good till 10...10:30pm. After 9pm I use headphones only.
Think, try and maybe you don't need to go through the struggle especially if it's all wife-acceptible...
