The 3R dramatically improves the sound from digital audio computer files, music streaming services (like Spotify, iTunes, Tidal, etc.), even from low-res YouTube playbacks! Ideon Audio's 3R USB Revive connects between the digital output (host) and the Dac. It achieves excellent sound performance by uncovering lost detail, enhancing dynamics, re-clocking the signal using ultra-low jitter oscillators, and minimizing transmission losses. The 3R is a class leader, outperforming all competitors! It will be an easy sell in your store once a customer hears a demonstration, it's a significan't game changer in the USB audio market.
