With our considerable experience in the design and manufacture of the world’s best consumer and professional amplifiers, this latest design of power amplifier utilises our high frequency power supply techniques and our own proprietary lateral structure dual-die MOSFETs. The SPM650 retains the clarity and style of our larger amplifiers but in a more compact case.
The Chord SPM650 stereo power amplifier is a full width design capable of driving low impedance loudspeakers, and delivers 130 watts rms per channel into 8 ohms or 170 watts rms per channel into 4 ohms. The dynamics of the SPM650 will indeed bring you closer to the music.
A high current mains filter ensures that the amplifier is shielded from disturbed mains as well as ensuring that the mains is untouched by emissions from the amplifier. The output from the power supply uses a truly innovative “Dynamic Coupling” technique whereby the positive and negative rails are mutually coupled by a strong magnetic flux. The result being that if a high demand is put on one rail, the energy required is actually drawn equally from both rails. This keeps the amplifier balanced dynamically and the reference point perfectly clean. Magnetic current sensors provide electronic shutdown.
The SPM650 comes fully loaded with both balanced and single input connections and gold plated speaker binding posts to accept both spade or banana cable connections.
Machined from solid aluminium the SPM650 has a superb rigid construction that gives unsurpassed vibration damping with stunning looks to match.
