IOT Electronic Allo Nirvana SMPS Designed to Power Audio Devices with The Lowest Noise. USA Plug Type

Adding this linear power supply to my music streaming device eliminated audible noise and now it performs with excellence.

Using on Allo digione signature player with very noticeable improvement to the sound. Also tried with Topping E30 DAC with excellent results!

I was using a mic that was connected to USB. Unfortunately, the power source was so noisy that it carried over into a 3.5mm patch cable from the microphone to a camera. I purchased this to see if it might reduce the noise. I did notice some drop in noise, perhaps 20-50% of the static was removed. Sadly, there was still too much static. So, I'm not sure if this is the application to which the vendor had in mind, but, alas, it wasn't good enough for my use.I would observe that the device has lovely build quality and lots of adapters. If you need a 5V power input source, via USB connector or other round style adapter, this is a handy (if somewhat large) tool to have around. I give this a 4 because it did do what was said and I liked the product.

I love the nirvana
