It is designed to fully utilize the talents of these amazing valves.\u003c\/p\u003e\n\u003cp\u003eThis all tube pre amplifier utilises special 17AX4GT Tube Rectifiers for Power supply duties, while hand selected 6CA7EH are used for the voltage regulation stages, Mullard CV4004\/12AX7 and Tungsol 6SN7GTB are implemented for line amplification.\u003c\/p\u003e\n\u003cp\u003eFollowing the rigorous design concepts of Cayin Soul 170C, the designers have implemented two Negative Feedback Settings: High and Low options are available, allowing the perfect tonal character of the Soul 170C to be dialled in for the listener.\u003c\/p\u003e\n\u003cp\u003eFour pairs of RCA line inputs, and one pair of XLR balanced inputs are available.\u003c\/p\u003e\n\u003cp\u003eOne pair of RCA outputs and one pair of XLR balanced outputs are also available - this makes the integration of the Soul 170C into any existing set-up as easy and as high performing as possible.\u003c\/p\u003e\n\u003cp\u003eA quite beautifully crafted anodised solid aluminium front panel has been used, with a fully vented chassis giving a luxurious finish.\u003c\/p\u003e\n\u003cp\u003eThe Cayin Soul 170C, like all the other products from Cayin only employs point to point wiring.\u003c\/p\u003e\n\u003cp\u003eThe entire circuitry (including the signal path) is painstakingly hand wired with heavy-gauge cable by true audio craftsmen.\u003c\/p\u003e\n\u003cp\u003eA bespoke soft-start circuit and a high voltage delay configuration are used, which fully protect the amplifier and significantly extended life of the more sensitive components.\u003c\/p\u003e\n\u003cp\u003ePremium Parts are used throughout :\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAlps Volume Control\u003c\/li\u003e\n\u003cli\u003ePorcelain Tube Sockets\u003c\/li\u003e\n\u003cli\u003eAudio Grade Capacitors (Coupling)\u003c\/li\u003e\n\u003cli\u003eCarbon Film Resistors\u003c\/li\u003e\n\u003cli\u003eIn-House Toroidal based transformers for the power supply\u003c\/li\u003e\n\u003cli\u003eIn-House Wide bandwidth EI output transformer.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOutput transformers are one of the most important part of any tube amplifier. They determine how low the bass will reach and how extended the high frequencies are - these attributes have significant impact on the amplifiers real world musical ability - with this in-house design ability, Cayin have managed to allow the full untapped potential of the Soul 170C to be realised.\u003c\/p\u003e\n\u003cp\u003eCayin output transformers are custom-designed, wound in-house, and over engineered - this enables us to implement a uniquely designed\/complicated multi-layer winding with multiple impedance's on the output to match perfectly with with the different and unique loads offered by the Power Amplifier.\u003c\/p\u003e\n\u003cp\u003eThis carefully matched output design , allows the Cayin Soul 170C to promote a more balanced, natural and realistic sound across the complete audio spectrum.\u003c\/p\u003e\n\u003cp\u003eThe custom designed Toroidal Power transformer offers unmatched\/ultra-stable power production and extreme low hum level providing a super-reliable performance and extraordinary control.\u003c\/p\u003e\n\u003cp\u003eComing standard with a full function aluminium remote control, the Soul 170C can also memorise the last operation of the unit once switched off.\u003c\/p\u003e\n\u003ch4\u003e\u003cu\u003eFeatures:\u003c\/u\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eFull Class A.\u003c\/li\u003e\n\u003cli\u003eHand-made construction with the finest point-to-point wiring.\u003c\/li\u003e\n\u003cli\u003eSpecially designed El transformer for the power supplies\u003c\/li\u003e\n\u003cli\u003eMullard CV4004\/12AX7.
