Cayin MT-35MK2 Bluetooth Tube Amplifier

CAYIN MT-35MK2 PLUS BLUETOOTH TUBE INTEGRATED AMPLIFIER

The Cayin MT-35MK2 Plus Bluetooth is a handcrafted stereo vacuum tube integrated amplifier combining traditional EL34 push-pull amplification with modern wireless audio connectivity. It delivers up to 35W per channel in Ultralinear mode and offers selectable Triode operation, three analogue line inputs and a dedicated headphone output.

EL34 PUSH-PULL AMPLIFICATION

Four EL34 output tubes operate in a Class AB1 push-pull circuit, supported by three original American General Electric 5BK7A NOS tubes in the voltage amplification and driver stages.

Hand-wired point-to-point construction, wide-bandwidth EI output transformers and a specially designed toroidal power transformer form the foundation of the amplifier. This architecture combines traditional valve engineering with practical output power for compatible passive loudspeakers.

SELECTABLE TRIODE AND ULTRALINEAR MODES

The MT-35MK2 Plus Bluetooth provides two operating modes, allowing users to select the amplifier's output configuration according to their listening preferences and loudspeakers.

Ultralinear mode delivers 35W + 35W RMS, offering greater available output power. Triode mode provides 18W + 18W RMS, using a different operating configuration that changes the amplifier's distortion characteristics and presentation.

BLUETOOTH 5.0 WITH ESS SABRE CONVERSION

Integrated Bluetooth 5.0 enables convenient wireless playback from compatible smartphones, tablets and computers. Support for UAT, LDAC, AAC and SBC provides flexible compatibility with different Bluetooth audio sources.

An ESS ES9018K2M SABRE32 DAC handles digital-to-analogue conversion for the Bluetooth signal, allowing wireless sources to feed the amplifier's vacuum tube amplification circuit without an external DAC.

ANALOGUE INPUTS AND HEADPHONE LISTENING

Three stereo RCA line inputs accommodate external music streamers, DACs, CD players and other line-level sources. Dedicated 4Ω and 8Ω speaker terminals support appropriate loudspeaker matching, while a front-panel 6.35mm headphone socket provides an additional personal listening option.

A Japanese ALPS volume potentiometer provides analogue level control. The integrated bias meter and external adjustment controls allow the output tube bias to be monitored and adjusted according to the manufacturer's instructions.

HANDCRAFTED CONSTRUCTION

The compact chassis combines traditional vacuum tube styling with carefully selected components and an accessible control layout. A removable protective tube grille is supplied, while the point-to-point internal wiring reflects Cayin's established approach to valve amplifier construction.

For listeners seeking an integrated tube amplifier with both wired analogue inputs and wireless convenience, the MT-35MK2 Plus Bluetooth provides a practical combination of traditional amplification and modern source compatibility.
