“Its cool too!” What is ProPlugin on about? The Nano iDSD LE! “The sound profile is quite clean. The sound is sweet and detailed.

“The Nano iOne is a welcoming and versatile device with excellent reproduction…the transmitter itself is in an elegant box made of aluminium profile enclosed by from panels.”...

May 24, 2017 Mark R Wietstock I read all the reviews, and thought a LONG time before buying this gizmo. I recently bought a very IN-expensive remote-controlled, DC-powered MP3 player that runs songs from a USB drive or SD card. It’s a convenient little device, but unfortunately, it also transmits a lot of “jitter” into the audio as it reads Continue Reading...

April 23, 2017 denti alligtor Does exactly what it’s supposed to do. I had a ground loop issue over USB. My options were to remove the ground on my amp (which is unsafe) or to get a USB ground isolator. This worked! Plus, it came SUPER fast directly from the manufacturer with a nice little note, too....

November 29, 2016 Brian I was skeptical of this finally solving an issue that I’ve had, which is finding a DAP or DAC/ that wouldn’t hiss using my Ultimate Ears Reference Monitors.
