6 vs2 - Integrated Amplifier

The new Cyrus Integrated 6 vs2 integrated amplifier is a wonderful place to enter the Cyrus range of products. It is the perfect match for the award winning CD 6s and when partnered by a set of good quality loudspeakers will provide outstanding musical performance from surprisingly compact components. Because the Cyrus Integrated 6vs2 is based on the Cyrus Integrated 8 vs2, it can be fully upgraded to the higher specification model.

The new Cyrus Integrated 6 vs2 enjoys the same acoustic characteristic as the wider family of matching Cyrus components. Because we have engineered the range to be upgradeable and acoustically setup to match, you can upgrade from the Cyrus integrated 6 vs2 all the way up to the highest X series in affordable stages as funds and your enthusiasm allow.

Our most affordable integrated amplifier boasts an impressive range of abilities. Amongst these is the uncanny skill to present a 3D audio picture of the recorded performance, along with surprisingly powerful dynamics for such a compact amplifier. The Cyrus Integrated 6 vs2 circuitry benefits from most of the development work of its larger sibling Cyrus Integrated 8 vs2.

Although we have accomplished significant savings by installing a smaller power supply in the 6 vs2, the main boards are almost identical. Once our customers experience a system of this quality they often consider upgrading to the next level of performance and the Cyrus Integrated 6 vs2 can easily be upgraded to full Integrated 8vs2 specification by our factory.

You simply return your Cyrus Integrated 6vs2 to our Huntingdon service facility where it is upgraded to full Cyrus Integrated 8 vs2 specification. The charge for this upgrade is only slightly more than the difference in price between the amps to cover labour and shipping. The amp includes our latest vs2 preamp topology.

After planning such an extensive development program for the Cyrus Integrated 8 vs2, the design brief for the Cyrus Integrated 6 vs2 amplifier was really quite simple – to design a 40W amplifier with all the new characteristics of its 8 series counterpart!  Quite a tough task when meeting the expected budget for a 40W amplifier. By scaling down the massive power supply of the Cyrus Integrated 8 vs2, this brief has been achieved in full with the Cyrus Integrated 6 vs2 inheriting the power amplifier and power supply design advances, the higher current output stage, the full complement of selected audiophile components, the soft standby switching and the advanced thermal management of the Cyrus Integrated 8 vs2.

With these attributes the Cyrus Integrated 6 vs2 is able to deliver remarkable specifications for a 40W amplifier. The rated 30A peak current capability and 173W peak power into a 1 Ohm load would not shame an amplifier of double this capacity. In addition, the ambitious Cyrus Integrated 6 vs2 owner has the further benefit of an upgrade path through full Cyrus Integrated 8 vs2 specification and beyond, by opting for a Cyrus factory upgrade.

System optimisation – The Cyrus Integrated 6 vs2 packs in all the essential features to optimise a quality audio system. A full 40W + 40W 8 Ohm output, six inputs plus full tape monitor, Bi-wirable speaker terminals, headphone output with dedicated power amplifier, Preamplifier output (for bi-amping) and a sophisticated control system with system remote control are all provided. Input sensitivity matching is also included.

New Virtual Servo preamplifier technology - This is a new generation of preamplifier designs from the Cyrus R&D lab and was originally developed for our most exotic preamplifiers. Now appearing in our more affordable models is based on the work achieved with our acclaimed Virtual Servo preamp, we have further developed this interesting concept to now include the latest generation of digital volume IC’s, hence vs2.  Further refining our vs topology has brought very worthwhile advances over the previous model.

High efficiency power amplifier – Sharing technology with the Cyrus Integrated 8 vs2, the Cyrus Integrated 6 vs2 also uses dual charge pumps with linear post-regulators for the power supply of the voltage amplifier stage, increasing and stabilising the supply, eliminating any trace of power supply ripple and noise, and with no sag under load. These high efficiency techniques ensure maximum power transfer from the power supply to the speaker load.

Higher current output stage – Featuring identical output transistors to the Cyrus integrated 8 vs2, the Cyrus Integrated 6 vs2 has a massive 30A current drive capability leaving plenty of headroom to deliver the currents demanded from the power amplifier stage when driving real music into a real loudspeaker load.

Audiophile component specification – Using the same topology and components in the critical audio signal path, the distinctive sound signature of the Cyrus Integrated 8 vs2 is clearly audible when auditioning the Cyrus Integrated 6 vs2.

New peripheral circuitry for soft standby switching - Electronic standby switching has always been a feature in Cyrus amplifiers. Electronic switching completely avoids the problems of contact degradation which occur in the speaker relays used in most other manufacturers designs. As these amplifiers age, the relay contacts degrade and contact non-linearity gradually rises, degrading the sound.

The Cyrus electronic system works by effectively ‘tri-stating’ the power amplifier to prevent it from delivering any current to the loudspeaker whilst set to standby, completely avoiding the need for a relay in the signal path. Secondary benefits are instantaneous disconnection of the power amplifier from the load if an external fault condition, such as a speaker short-circuit, are detected by the control system. In the latest revision of this system for the Cyrus Integrated 6 vs2 & 8 vs2, a more sophisticated control circuit soft switches the power amplifier silently between standby and operational modes.

Advanced thermal management – New thermal measurement techniques are employed by the computer control system of the Cyrus 6vs to intelligently control the outer skin temperature of the casting, maximising the thermal performance available to the amplifier in any environment.
