Astell&Kern unleashes the KANN ULTRA to reach new heights of sonic performance

Introducing the KANN ULTRA, Astell&Kern’s most powerful digital audio player to date. The first player in the brand’s award-winning KANN series of players to feature Octa-core processors, the KANN Ultra can reach new sonic heights with DAR technology, an upgraded DAC and Triple Output while delivering the most seamless user experience possible. 

Key Features

Next-Generation Octa-Core processor brings significant performance improvements. Featuring the latest flagship DAC from ESS, delivering a richer, more expansive sound with advanced modulation. Triple Output Mode to deliver natural, detailed sound when connected to demanding headphones. 

Separate amplifier/sound design for the Headphone Out, Line Out and Pre-Out ports to provide the optimal sound for each Digital Audio Remaster (DAR) technology. Dedicated Pre-Out delivers sound through a specially designed Pre-Out amplifier. Exclusive Line Out mode outputs the sound directly from the DAC bypassing the amplifier.

With the new internal design, the audio circuitry is separated from the processors – which include CPU, memory and wireless connection components – and is equipped with a dedicated shield to minimise heat and noise from the processor.

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.

James F.

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!

Guy H.

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.
