Einstein The Light in the Dark User Manual

1
Dear EINSTEIN customer!
With the EINSTEIN The Light in the Dark stereo amplifier, you have acquired that rarest of Hifi components
— one that conforms to the most stringent standards of electrical design and mechanical integrity. To get
the most from it, please take a few leisurely moments and peruse the following instructions.
The Light in the Dark is a component that deliberately eschews frilly features to focus instead on the core
essentials:
• Realistic reproduction with the utmost fidelity
• Rock-solid reliability for years of worry-free service
• Intuitive user interface everyone in your household can use
• Extended market value to protect your investment
The EINSTEIN The Light in the Dark does not sound beautiful, soft or energetic. Our goal is to design com-
ponents that integrate into existing systems with the absolute minimum of signal degradation or “artistic
license“. A stereo amplifier’s job is simple (though by no means easy): increase signal amplitude; pass
this amplified signal to the loudspeaker; take control of the transducers. Even the “world’s best“ loud-
speaker cannot correct for losses or errors incurred by the amplifier. Quite the contrary. A superior loud-
speaker will ruthlessly reveal any shortcomings in the amplifier driving it. Hence your decision to incorpo-
rate the EINSTEIN The Light in the Dark into your system was a truly informed one. Congratulations.
We extend our regards from Bochum and wish you much musical satisfaction from your new EINSTEIN
The Light in the Dark.
