My listening was focused on two particular aspects of performance. First, I approached the PowerQuest 303 as a potential solution to an audible problem with my system. Second I listened for any possible effect the unit had on the overall character of the system’s sound.

As a possible first for me, I must report on listening to my system without music playing. The baseline noise from my speakers was dramatically reduced once I introduced the PowerQuest 303 into the system. It’s a head-scratcher that an aging switch mode power supply with transformer issues would perform differently with a change in AC power. Even more, so that the hum from the ERCO DAC itself was slightly reduced. What is the root cause of this improvement? I do not know. But it was blatantly easy to compare without music playing. Just noise then less noise. This is a singular situation to be sure, but it illustrated to me that the PowerQuest 303 was doing something and that in my case that something was an improvement
