[QUOTE="Bob Lee, post: 98395, member: 4707"] Re: Power Feeder and Voltage Drop Upgrading the power distro to reduce voltage sag is good but unless the lack of performance you noticed was due to premature clipping, you won't improve the amps' performance. It's an oddly common misconception that mains voltage controls a power amp's gain--and therefore the loudness. Mains voltage does directly influence the supply rail voltages in most power amps, and therefore the voltage at which the amp clips. IOW, voltage sag will cut into headroom but unless it's so bad that it causes the amp to shut down or otherwise behave strangely, it won't affect the amp outputs. I concur with those who have suggested that the likely core issue is insufficient "rig for the gig" and resulting power compression. [/QUOTE]
