Custom HiFi Cables Ltd.



Exciting news from CHC Towers! We are releasing not one, but two new PSU products! Enter the Mini ARC6 DC4 PSU and the DC4 Lite PSU - we've listened to our clients, taken their feedback on board and come up with some great new PSU configurations to fill the gaps in our existing product line-up. We can now offer DC4 technology at a significantly reduced price! The Mini ARC6 DC4 is essentially an ARC6 DC4 in a smaller case with a few minor simplifications, and the DC4 Lite is a dual-output PSU that is a hybrid of our DC3 and DC4 architectures.


A note for any of our international clients based in North America or in the EU - Custom HiFi Cables' DC3 and DC4 PSUs (and some other selected PSUs) can be manufactured by one of our partners based in the US and the EU, this has several advantages for you - being able to pay in your local currency instead of converting to GBP, no import tax, no potential customs issues... you get your PSU cheaper and quicker! Another advantage is that your waiting time will typically be shorter than placing an order with us here in the UK - CHC UK's waiting list is currently short but it's expected to grow quickly quite soon. If you'd like to place an order for a PSU, then please just email us as usual at and let us know which country you're in, which PSU you're interested in etc and we can take your enquiry forward from there.


Dr Sean Jacobs of Custom HiFi Cables is going to the North West Audio Show on 18-19th June! He will be showcasing a selection of ARC6 DC4 level PSUs as well as power and audio cables. He will be exhibiting in partnership with Hamnett's Vintage HiFi and Avondale Audio, in room 146. Hope to see you there!


We are delighted to announce that thanks to all of our clients who have purchased from us in April, we managed to raise a total of £1359.40 for the Tabletochki Charity Foundation! Thank you all for your help!


We are shocked and saddened by the ongoing abhorrent and senseless war in Ukraine. Millions of Ukrainians now face unimaginable tragedies as their sense of peace and security is challenged. The most vulnerable victims of this war are the children, therefore we decided to support a cause that helps children with cancer in the Ukrainian war zone.

5% of our total turnover during April will be donated to the Tabletochki Charity Foundation.

Needless to say we unequivocally condemn the Russian government's actions against the Ukrainian people, and to this end we have stopped trading with clients within Russia indefinitely.


CLEARANCE SECTION HAS BEEN UPDATED! Including an upgraded NAC92/Flatcap/2xNAP90 system


The ARC6 upgrade for the DC4 PSU has now been officially released - this can be fitted to existing DC4 PSUs as well as new builds. We have also released an unregulated PSU, which also uses the new ARC6 module and is specifically designed for ATX convertors, such as those made by Taiko Audio and others.

EXCITING NEWS! Dr. Sean Jacobs has made the DC3 and DC4 PSU modules available for DIY use - the range comprises the DC3 regulator module, DC4 regulator module, DC3 rectifier-capacitor module, DC4 rectifier-capacitor module, the Current Boost module and the HCX (high current rectifier) module. The ARC6 DC4 module is not included however. You can make enquiries/place an order by emailing us in the normal way, and the preliminary list of modules is available to view here: DC3/DC4 DIY modules 


We are now taking orders again, following our recent break due to bereavement. We do currently have a number of existing orders to be completed, but please do email if you are thinking of placing an order and we will do our best to fit you in to the build schedule.


CHC is VAT registered, effective from today. The website has been updated to show VAT-inclusive prices. There have been some ex-VAT price reductions in many cases. For any clients outside the UK, you will not be charged VAT. Please email if you would like confirmation of prices.



We have also created a new product page for the specific DC4 model to suit the Chord DAVE DAC, you can see it here:

DC4 (and DC3) PSUs can now be ordered directly from our US-based business partner! This service is currently only available to clients based in North America, and should offer reduced waiting times and lower shipping costs, plus the ability to pay in USD. Prices have been added to the DC3 and DC4 PSU webpages, to order just send us an email as per usual.


Yes, the website looks a little different right now! I've migrated to the latest Google Sites layout, please do bear with me while I sort out page formatting, colour schemes, links etc. Use the left-hand menu to navigate the product pages. Stacked pages can be navigated by clicking on the up/down arrow to open/close the hidden lists of product pages (clicking the text itself doesn't navigate the menu).


A few recent additions to the clearance section - a 2.1m set of speaker cables and some other things.


The DC2 PSU is now discontinued - we do still have around 10-12 DC2 PCBs in stock though, these are available as assembled and tested boards for DIYers to make their own PSUs around (case and transformer are required plus sundry items). Please contact us for details.


The COVID-19 state of partial lockdown continues - however, at CHC it is 100% business as usual, as we are a home-based business anyway. Couriers and the postal service are working almost normally at present as well, although an extra few days allowance for international deliveries may be needed for some countries. Email us with an enquiry if you would like up-to-date information.


Exciting news, we have expanded our range of DIY kits/modules and parts - good news when you are stuck at home and bored! The products range from ready-built modules to blank PCBs that you solder yourself - Upgraded voltage regulator modules, our valve-hybrid headphone amplifier and a remote-controlled passive preamplifier kit are all on offer. The DC2 PSU circuit board is also now available (website to be updated with this). See the new kits now here: DIY Parts


Today, on the 9th anniversary of the founding of CHC, we are pleased to announce our new ULTIMATE PSU - the DC4! You can read about it here: DC4 Power Supply


As of November 2019, the reputation of Custom HiFi Cables Ltd. has grown to a point where demand for my products is constantly high. As most of you know, I build everything myself to custom order, and as a small UK business I also wish to remain below the VAT registration threshold, which also limits me in terms of the value of orders I can take each year (although believe me, this threshold is high enough to keep me very busy almost all of the time!). As word of my work and my reputation has spread throughout the industry and around the world, I now find myself at a crossroads - do I expand the business, buy/let some larger premises and employ several staff to help me meet the demand, and take on all the risk and stress that this entails, or do I stay as I am and limit the orders that I can take? There is a third option that I am hoping can one day come to fruition though...

As many of you know, I work in partnership with Innuos, who build the superb Zen, Zenith and Statement music servers, which have all been incredibly highly praised by the hifi press. I design the PSUs for all Innuos equipment, which has given a significant boost in the audio performance of their servers and also to their sales figures. It's an incredibly mutually beneficial relationship and am interested in working with several other hifi companies in the future in a similar manner, whereby I supply my PSU designs under licence and the manufacturer can then build and distribute their upgraded products, thereby allowing my designs to reach many more clients.

If you represent a hifi manufacturer who may be interested in working with me, then please do get in touch and I would be very happy to discuss a potential working relationship.


Welcome to the online home of Custom Hifi Cables Ltd. Recent news items are announced on this front page, for our product pages you can navigate using the left-hand menus.

We offer a very reasonable 5 year warranty on all of our products, because we're so confident in the high quality of our construction and design.

All of our DC3 and Naim PSUs use version 2.1 of our fabled CHC-REG regulator modules. Clients claim that these PSUs outperform the equivalent DR-specification PSUs from Naim and other manufacturers, so contact us today to ask for more details or a demo.

We offer a comprehensive Naim Audio Servicing and Upgrades service, for almost all of your Naim Audio servicing needs. We will also willingly upgrade the equipment above and beyond its original specification to further improve its performance, if desired. We also offer a complete range of replacement Naim PSUs, which offer significant upgrade for a fraction of the price of even a second-hand Naim PSU (which would come with no warranty of course and would need a service anyway).


Our company was established in 2010 in order to sell high quality hi-fi cables and power supplies at extremely competitive prices, which we are able to offer through exclusively selling online and also developing and manufacturing all of our own products in-house. As a result, our products are pretty much unbeatable for the money - we challenge you to find better products at a similar price!

What sets us apart from the other cable and PSU companies is that we are extremely happy to customise any of our products to your exact personalised requirements, whether it is simply making a cable to a precise length or designing a complete power supply and interconnect solution for your whole system.

You can use the left-hand menu to view more information about us, our contact details, and of course our full range of cables, PSUs and hi-fi accessories. All of these products can be customised - the most popular customisation options are listed on the right-hand side of each product page, along with prices, but if there is something you need that you can't find then please email us and we will be happy to help as much as possible and quote for customised products.
