Cayin M-845i Integrated Tube Amplifier 
 
Introducing the M-845i Vacuum Tube Amplifier: a hand-crafted masterpiece designed for audiophiles who seek the finest in audio performance. This amplifier boasts meticulous point-to-point wiring and incorporates two EI output transformers for ultra-wide bandwidth, ensuring a pristine sound experience. Its power supply topology features a specially designed toroidal transformer, delivering consistent and reliable power.
 
The M-845i’s preamp stage utilizes a hand-picked 6SN7 tube for voltage regulation, while two 6SL7 tubes provide voltage amplification. Additionally, the driver stage employs two hand-matched 6SN7 tubes. For drive amplification, it features two TJ Full Music 300B tubes with porcelain bases, and the 845 vacuum tube, used in Single-end Class A amplification, ensures unparalleled audio fidelity for each channel.
 
This amplifier offers switchable negative feedback settings, allowing you to choose between a soft, clean, original sound at -3dB NFB or a bold, dynamic, and fluid presentation at 0dB NFB. User-friendly features include accessible bias and hum balance adjustments on top of the amplifier, complete with a true ampere meter. A remote control provides convenience for all functions, and the M-845i can be used as a power amplifier.
 
The amplifier’s memory function retains the last operation setting once turned off, and the output level attenuates automatically for balanced input. High-quality components like the Alps volume control, German WBT top-grade speaker terminals, USA Multicap capacitors, and Japanese Takman carbon film audio grade resistors ensure superior performance. Heavy gauge silver-plated signal cables are used throughout, and an easily-installed tube cover offers protection. The M-845i is the epitome of luxurious audio craftsmanship, delivering an exceptional listening experience.
