I am using a dedicated (separate breaker) 20 AMP wall outlet >>> Emotiva CMX-2 >>> Panamax MR4300 >>> all audio and video equipment. Well within your $800 budget.
Recommendation for a power conditioner
I've never used a power conditioner before and thought now is the time, even if for nothing more than cord management. I'd be plugging a JL sub, an LG OLED set, a Classe CAV-500 amp, Classe Sigma processor, and Oppo 4K player into the unit. I'd like to keep it to around $800, whether new or used. Any suggestions? Thanks!
