Description

Generally in audio designs simple circuits tend to work and most important sound much better. However in many cases, simple solutions come with shortcomings particularly in audio in the form of questionable measured performance.

The Incito S is a contrary statement to this ‘rule’. As with the Incito, in the heart of the Incito S preamplifier beats a zero feedback power gain stage which consists of a small SET amplifier and a transformer coupled super triode using the ultra high trans-conductance E280F. This superb tube, which is made primarily by Siemens and is loaded with the highest quality step down transformer with reconfigurable secondary windings to support switchable gain.

Switches on the back reconfigure the secondary winding to switch between 20db and 14db of maximum gain.

This small SET amplifier can easily provide voltage swings of over 320V, stepped down to 80Vpp (or 40Vpp on the -6db configuration) while keeping transistor-like noise figures.

The specially designed step down transformer provides very low output resistance and more than adequate current to drive any load down to 50 ohms! This required a robust and passively filtered power supply.

Low gain version

A low gain version of the pre-amplifier is now available. With a newly designed 20:1 step down transformer, the pre-amplifier now has a gain of 8db and is the preferred choice with standard high-gain amplifiers. The output impedance is compatible and optimised to drive a tube power amplifier or solid state, and can drive any load down to 12ohm.

The power supply is built around the 5AR4 rectifier and uses separate double pi filtering for each channel with oversized chokes and high speed capacitors. The power transformer is encased in an external chassis, connected with a permanent umbilical cord. This design choice lead to improved noise floor figures of 20db, now well below the -110db mark.

For volume control we used the best-to-our-ears way of implementing a volume control apparatus… that is transformer volume control. The Incito S uses the same TVC and input system of our bigger preamplifier brothers such as the Impera II. To go even further we used the same AC link proprietary technology for the biasing of the small SET amplifier. The bias circuits are controlled and monitored by the use of a variable pot and a build-in meter which ensures bias tuning of the design is both easy and intuitive.

The Incito S comes with a metal cased remote control, with volume, input selection and balance control.

The Incito was already a great preamplifier and it was very hard to outperformed it with a design that could fit in the same chassis and keep the weight unchanged. The Incito S is our answer to that challenge and I believe we have succeeded.
