Cayin Soul 170i, KT170 Tube Amplifier: High-Power Integrated Tube AMP (Soul 170i)
Cayin Soul 170i KT170 Tube Amp
Cayins new SOUL 170i KT170 tube based masterpiece.
This is how the Soul 170i started.
Soul 170i is designed on the basis of the world class Tungsol KT170 Power Tube - we have bespokely designed the perfect amplifier to fully utilise the talents of this amazing valve.
Real world realisation of 130 watts of power in Ultralinear Mode or 75 watts of power in Triode Mode (per channel) is quite sensational.
Designed in a Class AB Push-Pull configuration, Soul 170i has implemented two pieces of the powerful KT170 tube per channel.
This all tube Integrated utilises a special 22DE4 Tube Rectifier for Power supply duties, while hand selected ECC83S are used for the voltage amplification stage, special 6SN7's for the driver stage, and of course the quite incredible KT170 output tubes.
Following the design concept of Cayin Soul 170i, the amplifier offers two operation modes:
Triode and Ultralinear.
As you can see from the above specifications these two different modes offer two different output power configurations.
However it is a lot more than just that !
Changing the output mode will result in a fundamentally different sound signature instantly for the listener.
Triode Mode is rendering, a richer, smoother and more fluid flavour - this can be wonderfully suited to vocal and instrumental music.
Ultralinear Mode has very impressive power and extension - clean with energy, ideal for music which has punch and dynamic reach and as such this offers excellent control and immense grip.
Three pairs of line inputs, one pair of balanced inputs and one pair of 'Pre-In' are located on the rear panel of the amplifier.
The 'Pre-In' offers the listener the possibility to connect another high end Pre-Amplifier, so that you can use the Soul 170i as a stand alone power amplifier.
Uniquely, Cayin have integrated one pair of dedicated subwoofer Outputs on the rear, allowing for the implementation of a high quality subwoofer into the set-up - this opens up additional opportunities to expertly extend the bass performance for the customers set-up.
Cayin also offer a set of fully balanced XLR inputs on the Soul 170i, again pushing the boundaries in high end valve amplifier design, and therefore offers the listener the ability to run a fully balanced set-up through the entire audio system.
