ASR Emitter II Basic

The Emitter II models are considered the ultimate in amplifier design by true music connoisseurs and uncompromising audiophiles. Almost entirely by word of mouth, a music-addicted and ever-growing fan base has developed worldwide, realizing their desire for a concert hall in their own home.

Powered by two separate power supplies, the most sophisticated loudspeakers and elaborately constructed dynamic transducers are driven to peak sonic performance. With an Emitter II Basic, music unfolds across its full dynamic range.

From the slightest breath to the slightest rustle on stage to the power of a full orchestra, the Emitter II Basic reproduces all tones neutrally, powerfully, energetically, with high resolution and without distortion in your listening room.

Especially at peak levels at concert volume, the reproduction and spatial imaging remain absolutely stable.

Quiet listeners also rave about the noticeable and very pleasant energy in the sound, which makes the music a relaxing and pleasant experience even at lower volume levels.
