X8 PowerBlock Professional

The X8 PowerBlock™ Professional stands in the middle of our range of high end US outlet blocks. A great all rounder for Hi-Fi and Home Cinema systems. Featuring eight Rhodium Wattgate™ sockets... in our opinion offers real improvements in sound and picture quality... will last a lifetime... and is a real talking point.





The X8 Professionalmodel features the well-regarded, high-performance Wattgate™ W381 RH evolution outlets; The best performing standard American sockets we've heard, specially treated with DeoxIT™ contact enhancer to maintain their performance and keep them free of oxidation (we use a special jig to get at the internal contacts).

Wattgate™ W381 RH evolution offer exceptional clamping pressure around plug pins for efficient contact and reduced impedance.







As standard, the X8 Professional block is wired with Kimber’s TCX cable. TCX is a heavy gauge copper cable, of the same quality as the individual wires woven together in our PowerKords™ but capable of handling higher currents.



Our X8 PowerBlocks™ are all fitted with our most sophisticated and powerful MegaClamp™ spike protection. We believe that spike activity on the mains supply can degrade the sound quality from your equipment (they can raise the background noise level in amplification circuits); remove them and in our opinion the sound is cleaner and clearer.

Our MegaClamp™ components were developed for use in the communications industry; we’ve found that they are the most effective way of absorbing spikes affecting your Hi-Fi or Home Cinema.


X8 PowerBlocks™ are fitted with a 10A IEC socket which allows you to choose the grade and length of cable you need to connect it to the wall socket. We recommend you opt for either the PowerKord-300™ or PowerKord-500™ for this application.





When choosing your mains cable, make sure you select the version with the 10A IEC connector. Click here to view PowerKords™.

PowerBlocks are made in UL-90-V0 ABS (a type of thermoplastic) which has been chosen specially for its sonic qualities (we’ve found that plastic extensions sound much better than metal extensions); durability; and the ability to resist shocks and high impacts. Additionally, the material is fire resistant and can be recycled.
