Integrated amplifier S.A.Lab Black Knight based on Germanium solid state devices was created for true audio gourmets. Expressive tube-like plasticity, excellent dynamics and heartfelt musicality fascinate from the very listening outset.
Audiophiles are well-known of Germanium’s outstanding virtues. At the same time the amplifier of this type are merely unique thing in Hi-Fi/High End.
Developing of S.A.Lab Black Knight took more than 3 years. Push-pull class AB unit contains Germanium transistors meticulously selected from large consignments produced in USSR.
Black Knight is sheer dual mono design with complete separating of signal, power supplying and grounding paths. There are toroidal transformers (2 x 360 W) and caps (2 х 160 mF) in channel’s power supplies.
Mr. Syomin paid great attention to output stage thermo and current stability which are monitored by microcontroller and large heat sinks (no active cooling). Before 18 W Black Knight operates in class A. Global negative feedback is not used.
Input selecting and volume control are relay switching. The amplifier has 5 line inputs (4 х RCA, XLR), bypass input and four pairs of pure silver speaker terminal for bi-wiring.
S.A.Lab derived Black Knight colour options from Ferrari line (Blue Tour de France is showed).
