{"id":15066441744761,"title":"Trilogy 993 Stereo Hybrid Power Amplifier","handle":"trilogy-993-stereo-hybrid-power-amplifier","description":"\u003cp class=\"\"\u003eComplementing the 903 Preamplifier. The best design choices can only be achieved by understanding all the options. Trilogy is in a unique position to do this; combining the best of both solid state and valve technology to produce a remarkable design that is capable of sublime musical subtlety and impressive power.\u003c\/p\u003e\n\u003cp class=\"\"\u003eAll the 993's voltage gain is provided by a 6H6П super tube. This Russian military triode has been selected for exceptional performance at audio frequencies, having both high transconductance and low mu. The valve operates in Class A in a grounded grid configuration with zero negative feedback for maximum fidelity.\u003c\/p\u003e\n\u003cp class=\"\"\u003ePower supplies for the driver stage are fully discrete and shunt regulated for excellent transient response. Because of the output stage’s unique topology the valve has an easy load, seeing only a small MOSFET. This enables it to deliver the musical flow and micro detail that makes valves so special. The 993 takes the unusual step of specifying a choke input power supply for the output stage.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe choke is nearly as large as the power transformer and plays a crucial role in the amplifier's performance. The electrically noisy, high current spikes that are pulled from the mains in conventional supplies are avoided. The choke allows a much more linear current draw instead, keeping dynamic noise under drive much lower. Premium reservoir capacitors and soft recovery diodes complete the power supply. The first watt delivered by an amplifier is the most crucial. It is where the majority of tonal and spatial cues reside at normal listening levels. The 993's output stage uses a small and agile output FET to serve this region, giving superior performance where it has most impact. When current demand rises, higher power bipolar devices supply additional current to move the loudspeaker with up to 125 watts into 8 Ohms.\u003c\/p\u003e\n\u003cp class=\"\"\u003eThe amplifier has zero global negative feedback, but because of high bias it still exhibits a low output impedance.

Because of the output stage’s unique topology the valve has an easy load, seeing only a small MOSFET. This enables it to deliver the musical flow and micro detail that makes valves so special.

The electrically noisy, high current spikes that are pulled from the mains in conventional supplies are avoided. The choke allows a much more linear current draw instead, keeping dynamic noise under drive much lower. Premium reservoir capacitors and soft recovery diodes complete the power supply. The first watt delivered by an amplifier is the most crucial. It is where the majority of tonal and spatial cues reside at normal listening levels.
