@emergingsoul thank you. Where do I start? I'm a firefighter and I have a degree in architecture. I have a very active life as a firefighter, designing and building. I love music and this space gives me peace. I wanted it to reflect the countryside. The bison skull is from a local bison farm. All the wood with the exception of the floor was all sourced locally from my property and nearby farms.
Acoustically my room isn't acoustically correct but I intend on correcting what I can with ceiling panels I've been considering. Unfortunately I can't really do much of anything on the walls given the interior finishes. But I did utilize 300 year old beams and split logs to create diffusors. And I have Rockwool Safe and Sound behind 3 walls.
This room was never really meant to be perfect but over the last couple of years I've become increasingly interested in HiFi. And this is a problem because I'm now forever analyzing everything - components, spkrs, interconnects, power cords, USB cables. So where do you draw the line?
These forums have been educational and I've connected with some fine people.
