iFi says that the iSilencer+ and iDefender+ remove electrical noise that distorts the audio signal. The current versions, iSilencer3.0 and iDefender3.0, are being replaced by new, improved models – the iSilencer+ and iDefender+
The new thumb-size ‘sticks’ plug into a computer’s USB socket.
The new iSilencer+ sports several enhancements compared to the outgoing iSilencer3.0. The circuitry has been upgraded with the addition of low-ESR (Equivalent Series Resistance) Tantalum capacitors for input and output filtering, with a “10-fold increase in filtering capacitance”.
It is also available in more flavours of USB; while the iSIlencer3.0 is only available with USB. Type A connectors, the iSilencer+ comes in three versions to include the newer USB-C connector:
• USB-A to USB-A
• USB-C to USB-A
• USB-C to USB-C
All versions support the USB 3.0 standard, together with USB 2.0 for backwards compatibility, and incorporate gold-plated connectors.
As well as plugging an iSilencer+ into the active USB output between computer and DAC, more ‘sticks’ can be plugged into spare USB ports to further reduce radiated EMI.
The iDefender+ is specifically designed to tackle ground (or earth) loops. Like the iSilencer+, the iDefender+ upgrades the performance of the outgoing iDefender3.0 with the addition of low-ESR Tantalum capacitors for input and output filtering.
It, too, is available in three versions to suit the connected equipment – USB-A to USB-A, USB-C to USB-A, or USB-C to USB-C. Again, the USB 3.0 and USB 2.0 standards are supported and the connectors are gold plated.
The iFi iSilencer+ and iDefender+ are available from Amazon and other selected retailers now. Both products are priced at £49 each.
