If you have a voltmeter you might try checking the outlets voltage both with and without your audio system powered up. If the powered up voltage is more than a couple of volts lower than when powered down, it's possible that either the outlet is defective or that your electrician inadvertantly didn't tighten a terminal tight enough, cracked a conductor or outlet component or tightened the terminal around some insulation instead of bare conductor. If there is an indicated problem it may be potentially hazardous enough that the breaker should be turned off until the problem is corrected.
Fancy Audio Electrical Outlet Causing Problems?
After having an electrician install a modified electrical outlet purchased from Bolder Cables the sound of my audio system has waned. It sounds lifeless, limp, like it's trying to get up but can't. No pop, no zing, no excitement. Is it possible that this outlet is causing a reduction in the quality of the sound? The components: McIntosh MA6500 integrated amp, Rega Jupiter CDP and Tannoy speakers. I've messed around with different component, cables, etc and the sound still sounds lifeless. Ideas appreciated.
