cyrus one hd amplifier
The new Cyrus One HD amplifier improves on many areas over the successful One amplifier. The circuitry and phono stage are improved, and the amplifier now uses Cyrus' 4th generation Hybrid Class D amplification, originally developed for the powerful all-in-one Lyric. Digital inputs have been added, including an asynchronous USB input, and Bluetooth gets a boost - aptX HD allows the wireless streaming of high definition audio from suitable devices.
As if the One amplifier wasn't good enough already...
The addition of a high quality, useable DAC for the Cyrus One HD opens up its flexibility and versatility. For this, Cyrus have chosen an ESS Sabre DAC.
The ESS Sabre DAC is capable of decoding any digital material up to 32bit/192kHz, as well as DSD128. The addition of this DAC allows digital inputs - the asynchronous USB input is perfect for the likes of Innuos media servers, and the optical and coaxial digital inputs are ideal for media boxes from the likes of Sky or Virgin, or media streamers like Sonos or Bluesound.
The Cyrus One HD amplifier uses a linear power supply with a large toroidal transformer to supply its 4th generation Hybrid Class D amplification, resulting in a powerful, low distortion amplifier with a very low noise floor, capable of a genuine 100wpc into 6ohms.
Speaker Impedance Detection (SID) is a useful feature which first appeared on the all-in-one Cyrus Lyric. On powering up, the amplifier detects the impedance of the connected loudspeakers and adjusts its output response accordingly to match the electrical load of the loudspeakers. This feature ensures you to get the best out of any loudspeakers you choose to pair with the Cyrus One HD, greatly reducing speaker matching issues.
All firmware updates can be performed by simply connecting the Cyrus One HD to a PC via USB.
It is capable of driving demanding, high impedance, high quality headphones without the need for a stand alone headphone amplifier, which is highly unusual for an amplifier at its modest price point.
The full power of the Cyrus One HD amplifier is directed to the headphone output when headphones are used, making the Cyrus One HD an extremely capable, powerful, high voltage headphone amplifier.
The Cyrus One HD amplifier provides three analogue inputs, as well as a high quality MM phono stage, which is now isolated to its own dedicated circuit board. Digitally, there are optical and coaxial digital inputs, and an asynchronous USB input. As well as a pair of analogue pre-outputs for adding additional amplification or a subwoofer, the Cyrus One HD also provides an AV bypass input.
As well as a pair of analogue pre-outputs for adding additional amplification or connecting to a subwoofer, the Cyrus One HD also has a dedicated AV connection, the fixed level of which can be adjusted via the free Android/IOS app. This Bluetooth based app also allows set up and basic control of inputs, balance, and volume, all without the need for 'line of sight' needed for conventional remote controls.
