My nerd cave. Happy to talk merits and limitations of system. Always thinking about better sound, without lamenting the way things are now. New room in 2023 with 2 sheets of 5/8" sheetorck with Green Glue in between, suspended off of rubber connectors to aluminum hat channel, plus 2 layers of rock wool. All outlets sealed with putty. 10/2 line to power amp, dedicated circuit for electronics.
