I just finished configuring a full 5.2.4 Atmos setup at home (Klipsch Reference Premiere + Onkyo) along with a TV much larger than should go in that room.
I no longer want to go to the movie theaters :)
But when considering I use it every day (netflix, spotify, 4 game consoles, 2 computers) it still costs much less than going to the theaters every other day for 2 years yet the experience is better; always got the best seat, no crowds, no commute, high-end quality :)
The way I think about it is in the long term. I'd rather have high-end stuff thats a one-cost expense I'm going to use for decades, than cheap stuff I constantly replace or upgrade. In the end I pay less and enjoy myself more on the way. I also set money aside when planning such purchases instead of using credit, while looking for sales in the meantime.
