Know before you buy
The hybrid design combines the natural, harmonic richness of a Class A valve input stage with the robust current delivery of transistor output devices. This allows the amplifier to provide the delicate midrange detail typically associated with tubes while maintaining the power and control needed to drive demanding loudspeakers.
By eliminating global negative feedback, the 993 avoids the phase errors and timing issues that can often make amplifiers sound sterile or compressed. This results in a more open, organic, and lifelike presentation that preserves the natural transients of your music.
The 993 is designed to handle a wide range of speakers with an impedance between 4 and 16 Ohms. With 125 watts per channel into 8 Ohms and 200 watts into 4 Ohms, it possesses sufficient power and current stability to control most high-quality floorstanding and bookshelf speakers effectively.
The choke input power supply is a sophisticated design choice that helps minimize dynamic noise and electrical interference. It ensures that the amplifier receives a clean, stable flow of power, which is essential for maintaining clarity and low-level detail during complex musical passages.
Yes, the 993 features TAS link connectivity, which allows for seamless remote switching and integrated control when paired with other compatible Trilogy components. This simplifies system operation while maintaining the high-end performance of the individual units.
Given its high-performance design and Class A valve input stage, the 993 generates heat during operation. It should be placed on a sturdy, level surface with adequate clearance around the top and sides to ensure proper airflow and maintain optimal thermal performance.
