Cyrus 8

Given a top quality source the Cyrus 8 will paint a truly 3 dimensional acoustic picture with stunningly focused staging of images. Over the last 20 years Cyrus has learned to tune each section of the musical range accurately, so today the Cyrus 8 is able to faithfully recreate the subtle balance between length of single notes and tonal balance. For more than a year we continued to tune the Cyrus 8’s sophisticated circuitry until we are satisfied that important low level musical information is transferred accurately to the listener. Only once this is correctly balanced can the amp provide the precise sense of timing and rhythm upon which much of music’s magic is based. Accurate interplay between musicians is based on subliminal information and is absolutely vital to the overall success of the system performance. It is this ability of Cyrus to finely balance circuitry throughout our systems that makes our components sing.

The Cyrus 8 was we believe a significant step forward in integrated amplifier design and will form a valuable and long-lasting cornerstone for your system.   Further Information The previous Cyrus 7 amplifier carved an enviable reputation in our industry for delivering first-class sound quality from within its compact, stylish Cyrus chassis. The ‘impossible’ brief for the Cyrus 8 amplifier was to take this formula even further, with more output power, higher output current, better power supply rejection, improved PSX-R upgrade and more sophistication in the control system. In the process of upgrading these performance ideals it was also appropriate to review the sound performance of the amplifier to establish the sound signature of the ‘8 series’ of products. Higher output power – They said it couldn’t be done! The Cyrus 8 delivered the most power yet from our chassis. Despite the power amplifier delivering a true 70W+70W RMS power into 8 ohms, no compromises have been made elsewhere in the amplifer. True to the Cyrus tradition the chassis also houses a traditionally designed power supply featuring an oversize 330VA power transformer and extra-large electrolytic reservoir capacitors.

The performance gains in the Cyrus 8 have been possible through new higher efficiency power amplifier circuitry, new thermal management techniques and a higher current output stage. High efficiency power amplifier – Dual charge pumps and linear post-regulators increase the voltage and stabilise the power supply available for the voltage amplifier stage, eliminating any trace of power supply ripple and noise, with no sag under load. The extra headroom that this provides swings the current amplifier further towards its rails, giving a full 70W 8 ohm performance. Higher current output stage – When driving real music into a real loudspeaker load, massive currents are demanded from a power amplifier stage. For the Cyrus 8 our designers have effectively doubled the peak current capability of the power amplifier and halved its output impedance to enable a far greater transfer of energy from the power supply into difficult speaker loads.

Audiophile component specification – In the Cyrus 8 particular attention has been paid to every single signal processing component within the preamplifier stage. Both active and passive components were selected without budgetary compromise and through exhaustive listening tests, delivering an unprecedented level of transparency to the sound. The same scrutiny has been applied to the selection of components in the Pre-Out signal path, essential where the Cyrus 8 is included in a bi-amplified system. Competent audio engineers will immediately recognise the quality which has been invested ‘under the hood’ of this amplifier. Advanced thermal management – New thermal measurement techniques are employed by the computer control system of the Cyrus 8 to intelligently control the outer skin temperature of the casting, maximising the thermal performance available to the amplifier in any environment.
