Cayin SOUL 170i
In 2018 Cayin developed its 25th Anniversary model A-845PRO which received a great response and amazing feedback from the market making note of its sensational sound performance mated to its elegant cosmetic design.
With the success of this model we have been thinking to expand the range and have a new reference line of products for Cayin.
Thanks to Tungsol and New Sensor Corporation announcing the all new KT70 flagship tube , this has now allowed us to bring to market a quite revolutionary amplifier design.
This is how the Soul 170i started.
KT170 Tube Based Masterpiece
Soul 170i is designed on basis of Tungsol KT170 Power Tube. It outputs 130 watts Power in Ultralinear Mode or 75 wats power in Triode Mode per channel. Designed in Class AB Push-Pull Soul 170i takes two pieces of powerful KT170 tube per channel. All tube Integrated with 22DE4 Tube Rectifier for Power supply, ECC83S voltage amplification stage, 6SN7 driver stage, and KT170 output tubes.
Following the design concept of Cayin Soul 170i offers two operation modes: Triode and Ultralinear . As you can see from above for these two different modes the output power are different. However it is not more than that. Change the output mode you will get a different sound signature instantly.
Triode Mode is Tendering, Rich in Harmony, Smooth and Soft. Ideal for Vocal and Instrumental Music. Ultralinear Mode has power and extension. Clean with energy. Ideal for music has punch and dynamic and at such mode it offers excellent control ability.
Three pairs of line inputs, one pair of Balance Input and one pair of Pre-In are located on the rear panel of the amplifier . In our Soul 170i not only the Single Ended RCA inputs provided but also the XLR Balance Input.
Different from other inputs Pre-In offers you a possibility to connect to some other Preamplifier so that you can the Soul 170i as a power amplifier .
One pair of Sub Output is located on the rear so that if you want to get more Bass you can use the interconnector to connect with your Subwoofer system. Speaker terminals for 4 and 8 ohm speakers are located on the rear panel of the Amplifier .
User bias controls for KT170 Power Tubes have been used for bias adjustment and one meter has been added to the top plate to allow you to monitor bias with ease. Anodized aluminum front, fully vented chassis with excellent gorgeous finish, and wood side panels give you a product of art in front of your eyes.
Soul 170i, same as other products from Cayin employs Point to Point wiring. The entire circuitry including signal path is painstakingly hand wired with heavy-gauge cable by craftsman.
Soft-start circuit and High Voltage Delay to protect the amplifier for extended life of sensitive components.
High Voltage Fuses are used in the amplifier for protection which are located on the top plate close to the Power tubes. In case there were failure of tubes the Fuse will react first that you can know easily where the issue is.
Premium parts are used throughout:
- Alps Volume Control
- Porcelain Tube Sockets
- Audio Grade Capacitors
- Carbon Film Resistors
- In-House Toroidal based transformers for the power supply
- In-House Wide bandwidth EI output transformer
Output transformers are the most important part of any tube amp. They determine how low the bass will reach and how high the top end goes. Cayin output transformers are custom-designed, wound in-house, and massive. Enable compliciated multi-layer winding and multiple impedance output to match with different needs. Carefully matched output will sound Blanced, natural and realistic across the complete audio spectrum.
Custom designed Toroid Power transformer with strong power production and extreme low hum level provides a reliable performance and extradonary control. Standard with remote control, Soul 170i can memorize last operation of the unit once switched off.
