Single Stereo.
All company CD players wer integrated with very good preamplifiers, sometimes with extra analog inputs. So, they need just to connect to power amplifier, to make complete high end audio electronics. Integrating CD with preamp turned out to be a successful solution, compact design with short signal path, convenient control, high sound quality.
Classic, tube amplifiers of Ancient Audio were the most famous. Of course, famous 300B tube amplifiers like Silver Grand Mono are still unnatched in absolute fidelity of sound. Unfortunately, they are big , expencive, with limited power, needed careful mainterance. However, constant development of Solid State technology gave new possibilities, impossible before. The critically acclaimed Lektor Joy CD player plays with a soft yet dynamic and natural sound, even though it is built entirely on solid state.
The best sounding is pure class A, single ended amplification. These same set of active elements delivers both positive and negative signal. It is no switching between active elements, a source of thypical class B amplifiers distortions, particualrry unpleasant at Solid-State amplifiers. Pure Class A Sinle Ended never became popular, due to huge power looses.
Sigle Stereo matches both worlds. It plays in Single Ended Class A at low signals, where the most of musical informations are present. Instruments decay, hall reverb, harmonics are silent sounds, critical to overal sound quality. Loud sounds, impact, attack needs more power from amplifier. So, at high signals, amplifier gradually moves to AB Class.
Single Stereo matches opposite worlds: tube-like softness, resolution , and transistor impact, power, drive . Despite of small size and rated power, it can drive most of audiophile speakers. Yet still being compact, mainterance-free device.
It is stereo amplifier, however intenranl build is dual mono. Each chanel has own, independent electronics, capacitor banks, power transformer. Only power socket, switch and cabinet are common.
Two high current toroidal transformers, special audio edition are applied.
Non-magnetic cabinet is made of aluminiujm and mineral glass. It gives sophisticated elegance for ages, unmatched to any metal finish
