Regular power conditioners don’t allow for momentary spikes in current, so in dynamic moments you will find a lack of dynamics. Electrical noise from your house/neighborhood sources and noise generated from other audio devices can pollute the power going to your amplifiers..etc, so a quality power conditioner would be useful in providing clean power. If you want clean power and dynamics, then you must purchase very high cost conditioners/regenerators.
Shunyata claims that my conditioner can provide a momentary 30 amps into each of six channels and the conditioner combined with noise reduction power cables take care of line noise and the noise from audio components.
