Isotek EV03 Solus
Positioned between the entry-level Sirius and highly acclaimed Aquarius in IsoTek’s range, the EVO3 Solus builds upon the design of the outgoing GII Solus by incorporating a number of technologies trickled down from the company’s top-end power conditioning units. Up to six audio components may be connected, delivering a cost-effective way to significantly upgrade the sound quality of every source and amp component in a hi-fi system.
Mains noise can be broken down into two types. The first is differential noise, which is typically caused by switching – everything from a light switch to the switch-mode power supplies used in common domestic appliances. The second is common mode noise, which emanates from a point source, such as a radio transmitter. These noise types are complete opposites, yet they exist side by side and arrive in the home via live and neutral mains cables.
IsoTek has enhanced a number of key circuits to ensure the EVO3 Solus tackles both differential and common mode noise with even greater effectiveness than the GII model it replaces. The sophisticated delta filter network has been significantly improved, while newly devised individual differential filtering is applied to each of the unit’s six outputs, preventing cross-contamination between connected audio components.
IsoTek’s proprietary K.E.R.P. and Polaris-X technologies are also integrated into the design. K.E.R.P. (Kirchoff’s Equal Resistance Path) equalises resistance across all outlets, thereby increasing the effectiveness of the internal filter networks. Polaris-X ensures that the electrons take the easiest route, thus reducing crosstalk and improving component-from-component isolation.
In addition to improved filtering, the EVO3 Solus delivers greater protection against spikes and surges in the mains supply, with 22,500A of instantaneous, repeatable protection on tap. In contrast to inferior designs, a full 10 amps of current can be drawn at any time, delivering power of up 2300VA with unrestricted transient ability – this is especially important for power amplifiers. Silver-plated oxygen-free copper wiring is used throughout, while the unit’s sturdy rack-width aluminium casing ensures it is built to last.
The system diagram below illustrates the various processes as electricity travels from a wall socket through the EVO3 Solus, to each of the six individually filtered outlets.
With advanced, proprietary technologies delivering class-leading mains filtering, the new EVO3 Solus is a superbly cost-effective way to enhance and safeguard any high-quality audio system
