You know, the small things that can save you a lot of money. I’ll start:
You can get “hospital” powercables that are completely shielded for 20 bucks or so.
You can get anti vibration pucks for washing machines instead of spending 10 times that on the same product which is just labeled as “speaker pucks” instead.
You can get a 14 day trial of Dirac live to Calibrate your Stereo system and up to 8 channels of home theater speakers for free and Save the outcome, you can also get that 14 day trial for every email you have so for future calibrations use another email…https://www.dirac.com/online-store/dirac-live-room-correction-suite/
