Founded in 1980 by Friedrich Schaefer, ASR remains loyal to its philosophy to reproduce music as a complete experience.
ASR amps are able to drive very low efficiency or low impedance loudspeakers with ample power. ASR manufactures integrated amplifiers, pre-amplifiers and Phono pre-amplifiers.
The concept is totally different from all other integrated amplifiers. The product is best described as a main amplifier with input selector and level control. The large, high quality, powerful transformers are installed into separate casings.
This design eliminates the electro-magnetic fields and vibrations from the amplifier. This is an essential precondition for the calm and relaxing sound picture of the Emitter.
