Overview
Why X Blocks™

Designed by us from the ground up, X Blocks™ are the ideal choice for any level of system requiring up to 6 sockets (for bigger systems, choose our PowerBlocks™). From a small CD player / amplifier combination up to a high-end system, X Blocks™ allow your system to perform more efficiently and effectively.



X Blocks™ are hand built to exacting standards by our highly-skilled manufacturing team and are guaranteed* to provide a lifetime of listening enjoyment. They're compact, attractive and versatile: simply choose how many sockets you need, specify your mains cable, then sit back and enjoy better performance from your Hi-Fi or Home Cinema.


X Block™ features

  • 2, 4 or 6 UltraSockets™. X Blocks™ are fitted with our top-of-the-range power sockets to ensure the very best connection. UltraSockets™ have a very high build quality and for good measure, every UltraSocket™ is Deep Cryogenically Treated and treated with DeoxIT contact enhancer.

  • Kimber internal wiring. We only use Kimber’s high purity TCX copper cable for wiring X Blocks™. This ensures full performance is maintained throughout the block with minimum impedance – each socket is optimised so there’s no restriction on where high-power components can be plugged in.

  • Bespoke ABS anti-shatter casework. It would be easy to spend lots of money on a shiny aluminium box but we believe this adds nothing to the performance – arguably, it degrades it. We use ABS because of its combination of strength, rigidity and acoustic neutrality. It also keeps the pound-to-pleasure ratio low too!



  • Silencer™ filtration. Each X Block™ is fitted with our highly-rated Silencer™ mains filter to reduce mains noise interference. It works passively, meaning that it has none of the drawbacks of many other mains filters – drawbacks such as loss of musicality and reduced dynamic range. It’s broadband too, effective at filtering over a wide frequency range. For the techies amongst you, it is a 'passive differential and common mode inductorless non-resonant harmonic filter'!

  • SuperClamp™ spike and surge protection. Each X Block™ also benefits from SuperClamp™ spike and surge components. Not only do these offer protection for your system, they also bring sonic benefits by addressing minor spikes and surges that appear on the mains on a regular basis. In our opinion, these high voltage spikes can raise the background noise level in amplification circuits which is why it makes good sense to try and reduce them.

  • 10A IEC socket. X Blocks™ are fitted with a 10A IEC socket, allowing you to choose the level of mains cable you desire. We recommend a minimum of the PowerKord-100™

  • Not just for use with smaller systems.

    Even if you’ve a bigger system, there are a number of places where you could use X Blocks™. Run out of sockets in your PowerBlock™? Add more by daisy-chaining an X Block™ into the spare 16A on the end of your PowerBlock™.

    You could use it for plugging in sensitive sources such as a CD player or turntable, and connect your amplification into your existing block. Or you could use it for connecting your mains filters and conditioners – such as your AbZorber™ or Clarity Pro™, leaving your existing mains extension for your Hi-Fi components.

    What Hi-Fi magazine

    What Hi-Fi? Sound & Vision magazine reviewed our X6 Block as part of a group test in their September 2015 issue. And it's fair to say that they really liked it!

    They quickly found that the X6 Block was adept whatever source material they played, finding that it makes for "a more revealing and seamlessly integrated listen". They found that the enhanced performance was "tangible, with impeccable timing and smooth integration, allied to an expansive soundstage and rigorous stereo focus."

    Summing up, they couldn't find anything to say against it, concluding "By allowing your electronics to give their best, this mains block is worth every penny".

    Paul Rigby reviews the X6 Block on his website www.theaudiophileman.com.

    The review compares the X6 first with a standard high street extension and then with a competitors offering.

    "Turning from a basic, bog standard, High St. power block ... playing Dexter Gordon's I Was Doing All Right and plugging in the X6, the soundstage sprang to life with a layered complexity that immediately forced a smile" he says. And the improvements continued, especially in the musicality of the performance. Listening to Gordon's sax with the X6 brought more emotion to the music and "was a lot smoother" than before. The double bass, which had been "largely absent from the basic power block" now provided the "rhythmic foundation" for the track. In fact, he observes, "You could hear the nuance of the plucked strings for the first time"!

    The results were just as impressive when moving over to Rock, with a recording of The Who's My Wife: "The lead vocal was also now much more interesting with the double tracked effects providing intriguing layering and depth to the performance"

    Moving onto a harder test for the X6, Paul compares its performance with a competitors' extension block and the results were still impressive. "In comparison, the X6 provided a superior bottom end, a greater weight and heft to lower frequencies that enabled The Who track to really rock... With the [competitors] block, there was a touch of upper mid bloom on vocal crescendos. That was removed with the X6, giving the track a sense of maturity".

    In conclusion, he writes that the X6 Block "is packed with enhancing technologies that all add to the enhanced sound quality". The X6 gets a 'Groovy' Award.

    "Simply Excellent"
    As technology develops, and equipment starts to sound tired, its natural to want to upgrade HiFi components? To that end, I have started using Bluetooth technology, but there were obvious issues with timing. When you consider the cost of some of the new components, everything was far from satisfactory.

    I have an X4 power block and a number of Russ Andrews power cables on another system, which I swapped into my upgraded system. I think we all know the benefits of Russ Andrews products, but I was rather surprised (and pleased) to hear a resolution to the rather irksome timing issues.

    "Exceeds Expectations"
    The whole performance has been lifted: cleaner treble, better resolution with more detail, much improved soundstage, everything really I'd hoped for only more so. This review is based on an un-modified LP12 majik., Art stilletto 6 v3s speakers. a 1993 Exposure 7 pre-amp with Exposure 6 power supply, Power amp is a Roksan 2. With the addition of the X4 block my system is now noticeably out-performing the shop system on which I auditioned the speakersn and that included 4 and a half grand's worth of valve amp. I did splash out on a Powercord 100 with DCT to connect the X4 to the mains, this I guess is making a contribution to just how much improvement I'm getting. I'm enjoying my new sound so much that plans to upgrade system components are shifted to the back burner. And I'm only 4 days into burn in.

    "A great investment!..."
    In short: A well worthy investment indeed: Smooth, good depth/extended Bass, good seperation with a detailed sound whilst retaining warmth/not too clinical.
    Nothing to do with the sound, but high quality, very well made and aesthetically pleasing too!
    Definitely recommended.

    "Outstanding Product"
    I have been using a X4 block for several weeks and the improvements are amazing. Sweeter treble, stronger base lines, deeper soundstage. Instruments previously hinted at are now clearly present. This is an outstanding product.

    "Purchase X4 Block Andyellow Power Cord"
    I have recieved delivery of an x4 block and yellow power cord today having placed my order yesterday. Thats very good service. The items are now part of me cyrus and Neat system. I the improvement in sound was immediate and beyond my expectation. I have now decided not to buy a more expensive amp as the quality is so much improved.

    "Way Overdue Review!..."
    As per Review summary, this is a way overdue review!: I have had this X4 Block set up and running for nearly a year now, but because of various other experiments etc. etc have left it until now to leave feedback.
    In brief it definitely does (on my system anyway) give a richer, smoother and in places a more detailed sound.
    If you try it back to back with your existing extension block with material you know off by heart, I will be amazed if you do not hear the benefits it brings.
    I should add it is made well made and although not important sonically, is as a bonus aesthetically pleasing!

    "Wow"
    After building work I re-installed my Rega, Elicit R, RP6 and Saturn R & sat down to few disks. It didn't sound right and I suspected the cheap extension block I had to use. I treated myself to an X4 extension block. This arrived quickly and I eagerly spun a disk. Cymbals sounded sharper but I was initially disappointed and decided it needed running in. I opened a magazine but a few tracks later I was no longer reading the mag, I was listening to a snare drum. This was not synthesised as I swear I could hear different weights and placements of strikes plus a fabulously sharp crack on each strike - wow. I was captivated. I have played this album many times but have never appreciated this element with this quality. With some age related hearing loss & really bad Tinnitus, clarity & quality of sound is critical for me. I was already very pleased with my system but it has just got a lot better.
