Works like a charm!

Perfect galvanic isolation of USB signals thanks to an ultralow coupling in the range of a few pF...great product, indeed!

Small dac

Small Dac, very nice sound. The accompanying app is less user friendly. Sadly Apple Music is not supported. But I guess that is Apple’s doing😢

High quality, excellent functionality, and sleek design.

I experienced frequent interference from my PC when using the WooAudio WA7 Fireflies USB DAC, usually triggered by GPU activity. The Neutron HiFi™ Isolator has completely resolved these issues. It's a great product, combining excellent functionality with sleek design.

Excellent accessory

I have no idea why no other manufacturer thought of that as carrying mobile and usb amp in the same pocket (these are MOBILE) devices inevitably leads to one or the other being scratched or chipped!
Excellent idea to have something like that and excellent, precise execution!

Stunning

Best USB dongle that I owned so far (compared to Dragonfly black, red and purple, tanchjim space, hiby r3, creative x-fi, akliam pd5).
In SE it beats the sound of my Hiby R4 in balanced mode (!) and most of my desktop amps when it comes to pure SQ.

HiFi Isolator

Works as it should. Be sure connect to the CPU with the arrow indicating the correct of the data.

I love it - Very high quality product !

It is smaller than expected, barely gets warm and the sound quality is exceptional. Due to its low power consumption it even works with my iPhone 14 flawlessly.
The true strength of this device is its DSPs though. I have tried a few devices with EQ and DSP before (Fiio KA17 for example) and they fall short when it comes to the transparancy and quality of the signal processing that the Neutron DAC has.
The PEQ and Crossfeed DSP are really well implemented. I cant tell a difference to any good implementations on the market.
Unlike with the Fiio which distorts and changes the sound in a bad and very artificial sounding way.

It really shows that the developer is very experienced with signal processing.
I am very curious how this tiny gem further improves throughout its lifecycle.
