The power amplifier is the final component in the signal chain before the loudspeakers. It is the workhorse of a hi-fi system. It takes the low-level signal from the pre-amplifier and converts it to a powerful signal to drive the loudspeakers. It has a low-level input to receive the signal from the preamplifier, and terminals for connecting loudspeaker cables.

Because of the power amplifier's unique function, it differs from other components in size, weight and use. High-quality power amplifiers are usually large and heavy. Moreover, the power amplifier is the component you don't need to touch and adjust. Consequently, power amplifiers are often placed on the floor near the loudspeakers rather than in an equipment rack.

Krell KSA-100 (KSA100) MK-2 Class A Power Amplifier
Krell KSA-100 (KSA100) MK-2 Class A Power Amplifier
A rare opportunity to own this legendary Krell KSA100 MK2 100W Class A Stereo power amplifier

The Krell KSA-100 Class A power amplifier was the first stereo amplifier from Krell Audio Industries.
At the start of the eighties Connecticut witnessed the birth of another highend audio company within its state borders: Krell Industries.
Class A power to the people could have been one of the inspiring thoughts for Daniel D'Agostino chief designer of Krell Industries. Of course there were already some Class A designs in the domain of the power amplifier, but most, and probably all of them were confined to relatively small power ratings. Even the huge monaural Class A amplifier from Levinson, the ML-2, could only muster 30 to 40 Watts of power at 8 Ohms. Other noteworthy low power Class A designs were John Bedini's 25/25 Class A amp and Jean Hiraga's 'Hiraga' Classe A. The only high power Class A amp in those days was a stereo 125 Watt Class A design from the SUMO electric company named The Gold designed by James Bongiorno.

Elac DPA-1-M (DPA1M) Mono Amplifier
Elac DPA-1-M (DPA1M) Mono Amplifier
DPA-1M Monoblock Hybrid Digital Power Amplifier

The DPA-1M Digital Power Amplifier doubles up on the DPA-1’s almost magical combination of power, musicality and efficiency. Even though it’s just 10.5 inches wide, the DPA-1M conjures up an incredible 325 watts per channel into 8 ohms. Because it’s a monoblock, power is doubled and the left and right channels can hit full output and maximum dynamics without impacting the performance of the other channel. Hearing this tiny, cool-running amp produce such incredible dynamics is almost as dazzling watching a wizard change a rabbit into a horse. But it’s not magic, just a masterful combination of a Class A analog input stage with a high-efficiency Class D output stage.

DPA-1 Stereo Hybrid Digital Power Amplifier:

The DPA-1 Digital Power Amplifier was created to perform not just in today’s stereo systems, but in tomorrow’s systems, too. The core of the DPA-1 is a wizardly circuit topology that combines the musicality of traditional Class A and Class AB amps with the power, dynamics and efficiency of the latest Class D designs. From a chassis just 10.5 inches wide, the DPA-1 delivers 125 watts per channel into 8 ohms and 200 watts per channel into 4 ohms, plenty enough power even for the largest tower speakers. It might seem like magic, but it’s just solid engineering.
