Cayin M-845i
- Fully Hand-made construction with the finest point-to-point wiring.
- Two EI output transformers with ultra-wide bandwidth are employed.
- Specially designed toroidal transformer has been implemented for the power supply topology.
- One hand picked 6SN7 has been used in the preamp stage for voltage regulation.
- Two 6SL7's have been used for voltage amplification while another two hand-matched 6SN7's have been used for the driver stage.
- Two TJ Full Music 300B with Porcelain base has been used for drive amplification.
- The 845 vacuum tube has been used for Single-end Class A amplification. One for each channel.
- Switchable between different negative feedback settings. It outputs a wonderfully soft, clean, original sound if operated at -3dB NFB. Otherwise it outputs an gorgeously open, bold sound with great dynamics, but presented with a more fluid and organic flavour if operated at 0dB NFB.
- User Bias adjustment, Hum Balance adjustment are accessible on top of the amplifier with true ampere meter.
- Remote control is providd for all functions.
- Can be used as a Power Amplifier.
- M-845i can memorise last operation of the unit once turned off.
- Output Level will attenuate automatically for the Balanced Input.
- Employs High quality Alps Volume control, and German WBT top grade Speaker terminals, USA.
- Multicap Capacitors and Japanese Takman Carbon Film Audio grade resistors have been used in the amplifier.
- Heavy gauge silver plated signal cable has been used throughout.
- Equipped with easily-installed tube cover for protection.
