This is currently my bedroom system. I enjoy listening to music and watching movies with it, but I would like to upgrade over time. I would say my usage is 70% music/30% tv/movies. I mostly listen to jazz, contemporary Christian, southern gospel, and classical.
I am currently in the process of upgrading my interconnects and speaker wire to Audioquest.
Upgrades I am currently considering:
Speakers: Bowers and Wilkins CM1 or 685.
Subwoofer: Polk Audio PSW111 or Definitive Technology ProSub 800.
As of today, I have installed a pair of Audioquest Cinnamon 1m HDMI cables in my system. While I have not tried to do immediate comparisons yet, I am pleased so far with the sound.
