In short, the Gizmo reduces noise and enhances musicality. I’ve been listening to LOTS of music lately. Analytically speaking, the Gizmo: increases truth of timbre; adds “air,” especially in the HF; extends the bass; provides more truthful mid-frequencies, adds body/density. I love this thing!
What is it? Kinda like a Majik (slightly smaller) with a built-in power cord. As for the internals, Dave will have to explain.
The longer story:
When system upgrades revealed grit in the high frequencies, a PIA Audio Majik solved the problem. In my system, the best integration of the Majik was powering the amp from its own dedicated circuit. The source is powered by an equi=tech (balanced power) from its own dedicated circuit. All variations were tested to come to this conclusion -- audio nervosa was fully engaged!
But the solution was temporary. My collection of noise killers also included a very nice parallel filter. The only downside of this filter is the time it requires to settle in after a power failure. During the summer months, there were many black out and brown outs. I spent the summer waiting for the filter to settle in.
Enter the Gizmo.
I pulled all the parallel filters in my system. It was obvious that the sound wasn’t what it had been. So, I did what any reasonable person would do – email Dave to explain and ask for a solution. That is right, I was able to communicate directly with a master of noise reduction who then built a solution!
Current setup:
Two dedicated circuits are used – one for the source and one for the amp. The Majik powers the amp and the linear power supply for the Touch. The Gizmo is plugged into the equi=tech; the source is plugged into the Gizmo.
Great stuff!

Back to the music…..
