Dedicated circuit

I agree that dedicated circuits make a difference, but I disagree that quality cables are then unnecessary. My experience is that having a dedicated circuit actually enhances the effectiveness of power cords and conditioners.

I have two dedicated circuits, one for my amps and a separate one for my front end. I agree w/ Brauser that far from obviating the effectiveness of power cords and conditioners, their effect is more noticeable. Good luck.

I have three circuits, one at 20A for each monoblock and another for front end stuff. IMO, this is the biggest bang for the buck on the power side of things and way ahead of fancy cords, outlets and conditioners. Another popular upgrade is a whole house surge protector, which I do not yet have.

I had a dedicated 20a circuit installed with a Porter Port receptacle.I noticed a slight difference but not as big a difference as when I added a nice power cord to my amp a year later.
