The SPM 650 is our most affordable full-width stereo power amplifier and yet it benefits from a range of proprietary technologies common to all of our amplifiers. The entry-level SPM 650 is ideal where space is tight: its compact chassis allows easy positioning in conventional equipment support racks, for an easy-install Chord power amp solution.

As with its stablemates, the SPM 650 features our proprietary high-frequency power supplies plus our own proprietary lateral-structure dual-die MOSFETs. The SPM 650 is a full-size design and despite its svelte appearance, it is capable of driving a wide range of loudspeakers, including low-impedance models.

Capable of delivering 130 watts into 8 ohms, or 170 watts per channel into 4 ohms, the space-saving  SPM 650 retains all the famous Chord hallmarks: power, resolution and transparency to name but a few. The SPM 650 is equipped with both balanced and single ended connections, plus gold-plated speaker binding posts, capable of accepting spade or banana cable terminations.

Further features include a high-current mains filter which ensures that the amplifier is shielded from disturbed mains, as well as ensuring that the mains supply is untouched by emissions from the amplifier.
