When it comes to amplifiers, there have always been two construction principles: Tubes and transistors. While tubes produce a captivating euphoria, because the technology used enables them to add harmonic overtones to the music signals, transistors deliver brute power to drive even the most demanding speakers. So why not combine both? This is exactly what the Magnat MA 900 does. We have combined two hand-selected audiophile tubes in the preamplifier together with powerful transistors in the power amplifier, thereby creating the symbiosis of sound and power.

MAGNAT MA 900 – TUBE TECHNOLOGY FOR FINESSE, TRANSISTORS FOR PERFORMANCE

Why use tubes anyway? Tube amplifiers, or rather ´tubes´ in the audio sector, have an inherent flaw. This, however, is an extremely pleasant flaw. They produce harmonic overtones. This means that a signal of 1,000 Hz is also reproduced with harmonics of 2,000 Hz, 3,000 Hz and so on. In doing so, the harmonics are naturally much quieter than the actual sound. Our ears perceive these harmonics as being very pleasant. The disadvantage of tubes, however, is that they are neither particularly powerful nor particularly efficient. This means you cannot really coax a lot of output power from them.

This is where the tried and tested transistors come into play. They are able to produce an impressive performance with an unadulterated sound, provided that you choose the right models of course. For these reasons, two ECC 81 tubes are used in the preamplifier of the MA 900. These are selected prior to installation. This ensures every MA 900 is equipped with two tubes that are perfectly identical in terms of their values. In addition, the tubes are also “burned-in” before installation. This is a process that takes several hours, during which the ECC 81 tubes are able to reach their final performance values. This ensures our MA 900 is capable of producing the sound for which our good name stands – as soon as it is unpacked.

Full-power performance – 200 watts x 2
While the selected and burned-in ECC 81 high-end tubes take care of amplifying the fine input signals and generate the inimitable tube sound, the power transistors ensure a solid continuous output of 200 watts of sine power per channel. The pulse power produced is an impressive 320 watts.

5 analogue low-level inputs and a 3.5 mm jack input at the front of the unit, as well as 4 digital inputs and a phono input for MM and MC systems, all guarantee connectivity for even the most extensive AV systems. Tablets, smartphones and computers can also be connected via Bluetooth with optimum sound quality thanks to the aptX HD standard.
