The USB Reinigen is a new high speed (480 Mbps) USB 2.0 isolator/re-clocker. 
It is based on the brand new Analog Devices ADUM 4165/4166 USB isolating re-clocking chips.

The main purpose for this device is to isolate and re-clock USB audio data between a digital source (such as a music server) and a digital-to-analogue converter (DAC) to maximise sound quality. 

 

Gieseler products are built to a high level of quality, and include a full two year parts and labour warranty. All parts are sourced from reputable suppliers such as Digikey, Element14, Mouser Electronics, and RS Components, to ensure parts meet our quality standards. Every unit is hand built in Australia by an experienced electronics audio technician.

 

Adding the USB Reinigen between a digital source and DAC is aimed at enhancing the sound quality in terms of separation, vocal body and general minimisation of digital edge or glare. High speed data is re-timed for jitter reduction using a low phase noise Seiko 24.0000 crystal.

 

Particular attention has been given to the internal power supplies as these are critical for optimal sound quality.  All regulators are ultra low noise & capacitors top quality Nichicon Fine Gold or Muse series.

 

The USB Reinigen also includes a double regulated 1 Amp USB A output connector, which often powers the USB input board on a DAC. The Reinigen provides a quality low noise regulated supply.  This can be very useful when connecting an external CD drive for ripping as not only does the drive receive ‘clean’ power but also the USB data is cleaned up.

 

Another  benefit from the  USB Reinigen apart from the the re-clocking is the fact that it provides full galvanic isolation between its two USB sockets.

What this means is there is no direct electrical connection between the USB sockets.

This is very beneficial when using  a laptop or streaming device that is powered by a switch mode PSU which most are.

With a switch mode PSU there is usually a small amount of mains leakage current that will flow along (& to) the DAC which will add noise.

By providing full galvanic isolation this leakage current path is broken & the leakage current is removed which is a good thing for audio.

This is achieved by using an extra internal EI core isolation power transformer.

It is more expensive but provides perfect low noise isolated power rather than the usual DC to DC converter which always contains some high frequency switching noise.
