Cayin SP-40M

With the same understated design, the same wood chassis, and the same elegant aluminum face as the preamp, the ideal companion to the SP-30S is the SP-40M power amplifier. With 10 W more than the integrated SP-10A, it allows for the use of speakers with lower efficiency.

A set of four KT88-EH tubes, one 12AX7, and two 12AU7s, along with a larger transformer, significantly increase the power. The timbre, musicality, and sound image offered are also those of the integrated amplifier.
