A little background
Let's face it - I probably take music a little too seriously. Some people enjoy it and others think it's a waste of money - I just say to each their own.
Probably more than you wanted to know about my hi-fi and music...
Hardware
If you really enjoy music, it makes sense to invest in a system that sounds good, or at least that's the way I defend these purchases. Overall, I've build my system around Squeezeboxes in different rooms and all my music stored (flac) on a NAS. If you're not familiar with Squeezeboxes, you can think of them as Sonos before Sonos was availble, or Roon before that was available. While there are advantages and disadvantages to all of the systems, I like that the server is open-source with a large community providing enhancements, and you can build your own hardware.
Right now, my system is composed of:Living Room
