Remarks

• "In order to defy the omnipresent competition from the Far East, Grundig's product manager Dr. Burkhardt Schwäbe realized in 1979, in addition to the no less legendary 5000 series, among other things, a series of noble compact devices that were intended to convey pure understatement - the Grundig "M series".

• The competition between two development teams resulted in a compact hi-fi system of exceptional quality at Grundig. Due to the large number of orders, the loudspeaker laboratory took over the development of the pre- and power amplifier, as the loudspeaker developers had already set standards with their outstanding active loudspeaker concept. The tuner came from the laboratory traditionally responsible for this. The result of the competition were top-class components that received unanimous praise from the experts.

If the name of the product manager sounds familiar, you may also know Dr. Schwäbe as the person responsible for the Fine Arts series that appeared in the second half of the 1980s.

The MA 100 has an output of 60 watts sinus per channel. Its special feature is the electrolytic capacitor-free output, which is responsible for the exemplary linear frequency response and the low-frequency attenuation factor of 60. The input level control allows easy connection to almost any preamplifier. Regarding the connection impedance of the preamplifier, the MA 100 harmonizes perfectly with the MXV 100 (and of course with any other high-quality preamplifier). Interconnect cables up to 10 m in length can be used without hesitation, allowing the power amplifier to be placed in close proximity to the loudspeakers."
