Using DIRECT battery power in all previous Ciúnas devices was a major step in addressing dynamically fluctuating noise. I believe that all voltage regulators, even the best ones, react with the circuit they are powering causing some noise instability - these batteries do not have such instability when supplying current to digital devices at high frequencies. This stability & ultra low noise battery power confers many audible improvements such as perceived increase in depth & solidity of sound stage, increased body to the sound, better timbre & perceptually louder - in a word more musicality.

 

Now using internal supercapacitors instead of batteries to power all devices 

See Technology for more in-depth information on components used. 

Isolating the USB signal carrying wires, thereby removing any common mode noise riding on these wires, further magnifies these same audible factors leading to even more realistic sound.

ISO-HUB Device

The ISO-HUB truly isolates & regenerates/reforms the USB signals before the input to the USB audio device - it is simply inserted before a USB audio device - a USB cable is connected between computer and ISO-HUB - USB cables can be plugged into it’s 4 USB ports, just like as USB hub works - to feed the isolated/reformed USB signal to any USB audio device plugged into the ports.

 

It consists of one USB input port & 4 X USB 2.0 high speed I/O ports that are both isolated & reclocked/reformed for best USB signal integrity.

Both sides of the USB isolator are DIRECTLY powered by a low noise, supercapacitor power for the very best signal integrity. Having tested this - supercapacitor power on the ‘dirty’ upstream side of the Silanna isolator sounds noticeably better than 5v USB power.

The importance of using the best possible power for recreating the signal with highest possible signal integrity, cannot be overstated - it is audibly significant. 

 

Supercapacitors are trickled charged when powered via a supplied charger PS. 

USE CASES

The 4 ports allow a number of USB DACs, USB to SPDIF converters or other USB audio devices to be plugged in. As an example a USB SSD or USB stick may be plugged in & audio files played from this.

 

Any device connected to the USB ports benefits from clean, reformatted, isolated USB signals.

 

ISO-SPDIF Device

 

The ISO-SPDIF consists of the above ISO-HUB technology combined with the Ciunas USB to SPDIF converter technology, implemented in one longer case (160mm in length). The USB to SPDIF converter used is the well-regarded Ciunas DDD converter.  This is the first truly isolated USB high speed USB-SPDIF to come to market. The input USB signal is isolated & reformed before entering the Amanero USB receiver & the I2S output signal is further reclocked by low jitter audio oscillators just as it enters the WM8805 SPDIF transceiver. This provides the cleanest SPDIF output signal possible. Along with this SPDIF output the ISO-SPDIF also has 3 USB isolated & reformed USB ports - the same as the ISO-HUB. This configuration allows for a number of different uses - it can be used as an isolated USB to SPDIF converter & it can be used as an isolated USB hub with 3 ports.

 

USE CASES

The ISO-SPDIF provides SPDIF output as well as USB output from a clean, isolated & reformatted USB input signal. It can be inserted between a computer & DAC which has USB or SPDIF inputs.

 

It can also can be used to provide a clean USB signal to another USB device. The rightmost USB port is already used for the SPDIF function so this should not be used.

 

Any device connected to the USB ports benefits from clean, reformatted, isolated USB signals as well as super clean 5V USB power.

As an example a USB SSD or USB stick may be plugged in & audio files played off this stick giving the the advantage of USB cleaning & reformatting of the USB signal

 

ISO-DAC Device

The ISO-DAC consists of the same ISO-HUB technology combined with a USB DAC (the very well reviewed Ciunas DAC) providing RCA analogue stereo outputs along with 3 USB isolated & reclocked ports. It comes in a single longer case (160mm in length) as the ISO-SPDIF above. Again, this is the first truly isolated USB high speed DAC to come to market. The input USB signal is isolated & reformed before entering the Amanero USB receiver & the I2S output signal is further reclocked by low jitter audio oscillators just as it enters the DAC chip. This provides the cleanest possible I2S signal to the DAc chip.

USE CASES

The ISO-DAC provides RCA analogue output as well as USB output from a clean, isolated & reformatted USB input signal. It can be inserted between a computer & preamplifier/amplifier. 

 

It can also can be used to provide a clean USB signal to another USB device. The rightmost USB port is already used for the SPDIF function so this should not be used.

 

Any device connected to the USB ports benefits from clean, reformatted, isolated USB signals as well as super clean 5V USB power.

 

As an example a USB SSD or USB stick may be plugged in & audio files played off this stick giving the the advantage of USB cleaning & reformatting of the USB signal

Battery ISO-PS Device

The battery ISO-PS is a battery power supply (case dimension: 4.72 x 1.69 x 3.07") using user-replaceable batteries delivering 5V & 7V outputs with continuous current output ratings of 2 Amps or more (but huge instantaneous current delivery headroom >120 Amps). The 7V output  is provided directly from the battery supply. The 5V supply is derived from a regulator driven directly by the 7V battery supply for the cleanest possible feed to the voltage regulator.

Supercapacitor ISO-PS Device

The supercapacitor ISO-PS is the latest PS device delivering isolated dual 5V outputs with continuous current output ratings of 3 Amps or more (but huge instantaneous current delivery headroom >120 Amps). The 5V output  is provided directly from the supercapacitors not through voltage regulators for the cleanest possible power source.

Other voltage outputs PSes are under development
