was looking for system improvements that are low cost. It's a great idea for a thread!
"Things you can do for free that improve sound quality"
I'll start:
Connect speaker cable to biwirable speaker diagonally, + on bass, - on treble. Leave jumpers normal.
Choose vinyl, if available
Improve speaker placement for smoother bass response at listening position, like WASP, Master Set, Iron Chef, etc.
Take care of yourself. Music sounds better when you are happy! Protein, sleep, minerals, exercise, help others
Remove any unused, idle speakers from the room
Reduce noises in the room like fireplace rattles, HVAC vents
Tighten your recepticle screws and wirenuts all the way back to your service panel
Listen with a friend
What are your favorite free or really cheap tweaks?
