ONKYO Integra MA-1000

Commentary

A 330 mm wide compact size pre-main amplifier developed with regular-size Integra technology.

In addition to the conventional power transformer, it is equipped with an in-phase transformer that eliminates the influence of noise when the speaker is connected. This is a double transformer drive system.
As a result, it is not affected by a large phase shift in the vicinity of the fo of the speaker, and the low-range braking is greatly improved, which enables a faithful speaker drive.

The basic configuration consists of two amplifiers, a straight high-gain equalizer amplifier and a power amplifier, ensuring high purity.
