Now with more connectivity than ever
The latest Cyrus ONE HD now comes with both digital and analogue inputs, making it the ideal hub for all your home entertainment. With connections for your turntable, two line level sources, optical and coaxial digital, asynchronous USB and Bluetooth aptX HD, the Cyrus ONE HD takes it all in its stride.
Get the very best sound from your desktop or laptop
For the best sound quality from your desktop or laptop, connect via the asynchronous USB input. This bypasses your computer’s internal soundcard and in effect, ‘controls’ the output signal. This allows the best use to made of the Cyrus’s top quality digital circuitry, including the ESS 32-bit DAC. If you’re a fan of Hi-Res music then this is the best possible way to hear your music files.
Digital inputs – perfect for smart TV and music streaming devices
With both optical and coaxial digital inputs, you can use a wide range of digital sources with the ONE HD. Most TVs, set-top boxes, smart TV devices and Blu-ray players feature a digital output, meaning you get the benefit of this amp’s top quality sound with your AV components as well as your stereo ones.
Higher quality Bluetooth connectivity with aptX HD
With the latest aptX HD compatibility, the Cyrus ONE HD gives higher quality, wireless sound than ever. If you subscribe to streaming services such as Tidal and Qobuz, you’ll now enjoy true Hi-Res audio quality when streaming wirelessly.
Turntable input
Cyrus realise that many music lovers have a cherished vinyl collection as well as regularly using streaming services. For this reason, the ONE HD is fitted with a good quality MM (Moving Magnet) phono pre-amp. No extra boxes required for plug n’ play vinyl playback.
Enhanced headphone output
Rather than being an afterthought, the headphone output fitted to the ONE HD is a top quality device in its own right – rivalling some standalone headphone amps. With your headphones plugged in, a dedicated Class AB amplifier draws exclusive power from the large toroidal transformer, giving huge reserves of current. The result is the ONE HD drives pretty much any headphones and drives them with vigour.
Integrate with your AV
Featuring an AV loop, you can use the ONE HD as the front channel in your home cinema system. Alternatively, should you get the upgrade bug, a pre-out connection lets you add a larger and higher quality power amp at a later date.
4th Generation Class D
Using Cyrus’s fourth generation of Class D digital amplification, the ONE HD produces a precise sound that’s typical of this world-class brand. With 100 watts per channel on hand, this baby amp produces a sound that’s anything but small. A big ‘3D’ soundstage, effortless dynamics and musical precision are all hallmarks of this class-leading amp. What’s more, SID (Speaker Impendence Detection) calibration gets the optimum performance from a huge range of different speakers.
Control app
For total convenience, you can control all of the amp’s many functions via a free app. Available for both Apple iOS and Android, the app gives a smooth-acting and clear interface that’s especially handy if you’re streaming music from the same device.
Stylish and compact
Despite packing in a 100 watt amp and impressive connectivity, the Cyrus ONE HD is still one of the most compact amplifiers in its class. The ‘shoe box’ size makes it ideal for tighter spaces where traditional, full-size hi-fi simply won’t go. True to Cyrus products heritage, the minimalist design also gives a timeless style and long-term user pleasure.
Versatility and performance come together to make the Cyrus ONE HD an unbeatable amp.

Great sound, really great amp.
I needed a small(ish) amplifier to fit a fairly small cabinet. After months of reviews I was drawn to the cyrus one HD and it has blown me away. It's a jump up from my old Cambridge audio amp, and I was literally stunned at the difference. I have spent several evenings now sitting in front of my 15 year old mordant shorts wondering how the heck they sound so good. I've never heard them/an amp sound that good. I'm not a hi fi buff but I know my stuff, and I love the Cyrus. I'm supprised at how much I love Bluetooth as well. I wasn't expecting to use that function much, but I've been streaming so much from the phone. As the amp is tucked away I notice the signal can drop out a bit, but it still works well. The app controller worked better than I expected as well. Some reviews have knocked this, but it has worked well for me. I'm now in the process of upgrading my old speakers. The cyrus amp is quite powerful, which should give me a bit more choice in speakers. Looking forward to it.
Wish I did this years ago.

Superb sound, incredibly easy set up
Bought this last week, paired it with a Rega Planar 2 deck and some B&W speakers. Couldn't be happier playing LP's I had forgotten I had with such great sound. The Bluetooth Connecction is also a bonus to stream from the phone. Spotless service from Richer Sounds, delivered in a couple of days to a one hour slot.

I purchased my amplifier from Richard at Richer sounds Leicester store. I called Richard at the store a couple of times before making my purchase to discuss questions I had about the amplifier . Richard was more than happy to take the time to help and had good hifi knowledge. I received a great purchase deal and extended warranty package and delivery was made two days later spot on time. The Cyrus is a awesome sounding with lovely bass and clarity with plenty of punch. I am happy i chose Richer sounds for my purchase . This store gives me confidence to buy again . Thanks Richard.

Bought thr Cyrus as an upgrade to a Kenwood amp I'd had for years and to match Bowers and Wilkins speakers that I knew should deliver more detail. WOW did it ever, once set up and connected played Vinyl and CDs the difference in sound was instant, I was hearing details that I'd previously been unaware of, frequencies that I'd only heard at concerts/gigs, a soundstage that opened and I could pinpoint instruments. The only downside is that I think I need to upgrade my old Pioneer CD player

Capable, understated amp with smooth, subtle power
Okay first off -- slight confession, my hand was forced a bit when I bought this, because I needed a shoebox-sized amp with an in-built DAC (for limited rack space reasons). I'd always been intrigued by Cyrus... ever since they were launched by Mission in the 1980s. I have in the past owned amps by Rotel, Arcam and Naim. My last amp was a Naim Nait 1 - which I've always viewed as a legendary product, and whose "up front" sound I love. That was going to be a hard act to follow. I was prepared to be disappointed, having read the four star What HiFi review for the Cyrus One HD - but I needn't have worried because this amp is EXCELLENT. It's got a smooth, slightly laid back delivery which seems to have turned the What HiFi reviewer off, but I think to allow that to colour your thinking would be a BIG mistake. Yes this amp is not as "in-your-face" as some, but I find it totally beguiling and musically enjoyable. You need to replace the supplied cheapo power cable with something half decent (I am using one from the excellent Mains Cables R Us), and use some lively speaker cable, like Tellurium Q Black. What you get is a lovely, rich and yet sparkly sound, plenty of depth and terrific stereo imaging. The sense of pace and rhythm is also excellent and there is a deceptively powerful bass holding everything together. The in-built DAC gives as good a performance on the optical out from my TV as my previous set-up (Audiolab MDAC+ playing through Naim Nait 1). In fact, I do believe speech in TV programmes is marginally clearer with the Cyrus One HD. It picks up any music with just as much brio as my previous combination. The phono stage is also good -- it seemed a bit "flat" at first but after a few days of warming up/listening in has loosened up nicely. My impression of listening to this amp is exactly that... it has a pleasantly liquid quality, very free-rolling and easy on the ear. If you do a lot of listening this is the amp for you, because you will not get ear fatigue. It's one for those who want to curl up on the sofa and listen to a few albums. You may even find yourself bouncing around the room if it's dance music. The detail and musicality is there even at low volumes. If you want the "blow your socks off" kind of performance that the What HiFi reviewer seemed to crave, maybe look elsewhere. But if you are mature enough for a polished, highly musical performer - and are willing to invest in a decent power lead and speaker cables - this is a total winner. Four stars? Don't make me laugh - this is without a doubt a FAT FIVE STAR AMP, and in my humble opinion you cannot go wrong for under a grand. The engineers at Cyrus have pulled off something pretty special! Oh yeah and it looks totally classy too.

Great sound, great connectivity
I bought this as a replacement to my original Cyrus One and I'm very happy with it. The sound is excellent and the connectivity is great - playing music via bluetooth from my phone works very well. Also has phono input and a number of others. Bluetooth remote control app works very well too.

I bought this a month ago from Richer Sounds Manchester during lockdown.
I needed to replace my Arcam Alpha7r and discussed options with Paul over the phone.
The service and quality of advice was excellent.
I had had the Arcam for 20+ years so was a little hesitant making such a significant change. The One HD is simple to operate and looks elegant. It works very well with my Pro-Ject Classic TT and Dali speakers.
Sound is excellent.
Very happy with this purchase and service/advice received.
