The a100 is the most affordable integrated stereo amplifier in the Opera Audio product line. There are almost no other competitors at or near its price. The solid-state amplifier has a simple design, is easy to use, and delivers pleasing sound with tube-like lucidity.
As our ahead of schedule production realization of solid-state amps using IC originally designed exclusively by Opera audio, the b2000x might be the best solid-state integrated stereo amplifier ever offered by Opera audio. This remarkable unit includes a well-improved, 100-watt per channel, push-pull Class AB power amplifier and a real built-in IC preamplifier stage.
