There are a few options as well. The case can be ordered in black, in a resin hardened case for more challenging environments, and you can choose a solid LED light over a blinking one to indicate high speed transfer. Mine was requested with a solid LED. Intonta designed the Isolator for a number of applications, including:
Set Up & Listening
The Intona was used in the main system between a Bryston BDP-2 server and BDA-3 DAC. An iFI Gemini USB cable ran from the BDP-2 into the Intona, then a Wireworld Platinum Starlight 7 USB cable ran from the Intona into the BDA-3. That was it. The intona is hub powered, so no other considerations came into play. After that I picked up my iPad Air and selected music, as I would any other day.
ConclusionI admit to previously not being totally in love with USB audio. It always sounded fine for a while, then inevitably I would notice an artifice that became annoying. AES/EBU seemed to sound more natural to my ears. But in the past year or so, with devices like the iFI iUSB 3.0 and others, and with properly terminated and spec’d USB cables, I no longer feel it is a compromise. To be fair, DAC designers have greatly improved their USB inputs and and there are more and more devices coming to market with higher quality USB outputs.
Ultimately, you want your source and DAC to communicate with a clean signal path, but you do not want the source to pass on any jitter, noise, or other artifacts which will detract from musical enjoyment. The Intona High Speed USB Isolator is a device that does exactly that by creating a new USB stream and isolating your source and DAC from each other. I can’t think of a single negative about the Intona device. Without a doubt it improved the sound of my system, not just changed it. While it is not as cheap as several other similar devices, it is made in Germany and does not require a power supply.
Highly, highly recommended.
