integrated amplifiers
CPM 2650, CPM 3350
Chord's integrated amplifiers are based on a combination of our highly
successful pre-amplifiers and power amplifiers together with a few features of their
own.
The power amplifier is based on Chord's tried and tested technology of ultra high
frequency ESR power supply which has the ability to store more energy far more
efficiently than conventional designs.
A variety of outputs means that you can choose to drive up to two sets of
loudspeakers, use your integrated amplifier as a pre-amplifier or use it in conjunction
with another power amplifier for bi-amping.
