EINSTEIN writes: "Why is the fully symmetrical circuit design of EINSTEIN The Silver Bullet OTL so unbeatable? It's simple: The amplifier switches precisely and quickly – without a sound limiting output transformer in the signal path! The loudspeaker is directly attached to the output tube of our Silver Bullet OTL. A circuit concept that we have not invented, but perfected." 

"Our monoamplifier is the uncompromising and reliable realization of a HiFi-Vision: Due to a special control technology (developed by EINSTEIN) it is possible for us to make maximum use of the great advantages of an OTL circuit. There is no relay in the signal path to the loudspeaker – the speaker is directly coupled to the end tubes and still 100% protected. For ultra-fast, broadband, phase-linear and absolutely realistic reproduction quality!"
