Chord Electronics a British HiFi manufacture, develop award-winning proprietary processes without compromise; technology at the apogee of its game. They are unapologetically unique: they don’t follow convention, they provide extraordinary sound and a mechanical design to suit your lifestyle.

As with all Chord Electronics products, their avionics heritage inspires only the highest quality: all of their products start life as a single billet of aircraft-grade aluminium. This is just one of the hundreds of processes that help shape their multi-award-winning devices; the same standards, care and attention run through the production of all of Chord electronics units.

When you place an order for a device in the Table Top range and above, your purchase is assigned to an engineer who will begin the process of curating each individual component before carefully crafting the unit to the highest standards. Only once it has passed numerous measured and listening tests, will it qualify for a Chord Electronics name badge. Naturally, this is a bespoke process that takes time, however, during your products’ build, you are more than welcome to ask your retailer any questions that you may have.

The Chord Electronics ULTIMA mono power amplifiers have been conceived for the very finest high-end audio systems, those which by their very nature, tend to have the most demanding and most difficult-to-drive large loudspeakers. They deliver unsurpassed power delivery and are capable of effortlessly driving any speaker.

ULTIMA is the company’s most accomplished amplifier in its 30-year history and one that draws on Chord Electronics’ three decades of proprietary-technology amplifier manufacturing. It features an all-new circuit topology, the first completely new design since those early days. The new dual-feed forward error-correction amplifier technology is a progression of Dr Malcolm J Hawksford’s (emeritus professor at Essex University) technical paper, refined by Bob Cordell of Bell Labs.

ULTIMA contains Chord Electronics’ next-generation amplifier tech, a design which features Cordell’s advanced dual-feedforward error-correction topology, plus John Franks’ own advanced concepts in ultra-high-frequency power supplies.

The ULTIMA mono amplifier unit has an incredible 64 proprietary MOSFET power devices that demand the most advanced and refined drive circuitry, suitably devoid of sound-degrading components. The drive circuitry features an ultra-low-distortion, high-voltage amplifier operating at very high speed: 300 volts-per-microsecond technologies with advanced feed-forward and feedback compensation techniques.

ULTIMA is incredibly powerful and offers 780 watts into 8 ohms, 1,400 watts into 4 ohms and 2,500 watts into 2 ohms. ULTIMA’s peak output current exceeds 500 amps, an extremely high current differentiated by the speed at which the dynamic peaks can be delivered, bringing astonishing dynamics, fidelity and unrivalled musicality.

ULTIMA is truly an unprecedented amplifier design with exceptional performance and is one of the most advanced hi-fi amplifiers in the world.

Testimonials

Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.

The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.

It’s now two weeks since I bought home my new system and I wanted to say thanks again for all your help, advice and guidance, not to mention cups of tea. I now have a system that meets all my requirements and sounds fantastic. Special thanks to Jon, who I hope is on the road to recovery from his operation and to Roger, who helped me finalise my choice. The Rega Saturn, Hegel H190V and Dali Rubicon 2 is undoubtedly the best system I have ever owned.
