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,
further elevating its noise-busting abilities 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 ‘SuperSpeed’ USB 3.0 standard, as well as USB 2.0 for
backwards compatibility, and incorporate high-quality gold-plated connectors for
optimal signal transfer.
As well as plugging an iSilencer+ into the active USB output between computer and
DAC, more iSilencer+ ‘sticks’ can be plugged into spare USB ports to further reduce
radiated EMI. Each time the number of units (and therefore the number ANC II
circuits) is doubled, noise reduction capability also doubles. And the iSilencer+ can
be used between external hard drives and music servers, too.
The precise effect of the iSilencer+ on sound quality varies from system to system;
typically, one can expect to hear more clarity, greater dynamic extension and
sharper leading edges, making the music sound more vivid and open.
