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.
STEREO POWER AMPLIFIER:
A power amplifier with two audio channels (left and right) in one chassis.
MONOBLOCK POWER AMPLIFIER:
A power amplifier with only one audio channel per chassis. Two monoblocks are required for stereo reproduction.

Duo 125 XD - 2 Channel Power Amplifier
125 Watt Amplifier Featuring Krell iBias Technology
Krell's New XD Technology
Krell’s “XD” (Xtended Dynamics, Xtended Dimensionality, Xtended Detail) upgrade for the iBias amplifiers takes analready great sounding amplifier and raises its performance to the next level. “XD” is a classic example of Krell’scontinuous R & D efforts reaping benefits across multiple product lines. During the development of the K-300iIntegrated Amplifier we discovered substantial sonic improvements by lowering the output impedance belowtraditional norms. So we applied this technique to our existing line of amplifiers and the improvement was sosubstantial that it required a unique designation, hence, “XD.”

Constellation Audio Performance Series Centaur II Mono Power Amplifier
|
|
New power supply with 3 times the capacitance. Higher bias current for extended Class A operation. 250 watts per channel into 8 ohms, 800 into 2 ohms. Fully discrete balanced bridged circuitry for extraordinary fidelity. Larger, deep-fin heat sink for efficient cooling and outstanding reliability
Think of Centaur II as a state-of-the-art race car with an upgraded engine. The amplification circuits are essentially the same as in the original Centaur, but the power supply is radically improved. Supply capacitance is now tripled, with 18 10,000-microfarad capacitors replacing the original six. With three times as much stored energy on tap, Centaur II now achieves even stronger deep bass response and more dramatic dynamics.

Astell&Kern AK500AP Amplifier and Power Supply
|
|
The AK500AP was developed as a small form factor to maintain the same design concept of the AK500N. Although its size may be small, it's able to deliver a remarkable level of performance through a combination of rigorously-selected parts and perfect design.
Approximately 3,000 times faster refresh rate was achieved by implementing a very high-frequency Switching-Mode Power Supply (SMPS) used in aerospace applications rather than a commonly-used linear power supply design, ensuring a full response to even the most complex waveforms. Despite its very small size, the power supply provides a full 1100W of capacity. In addition, a full balanced design was used to minimize noise interference, and Power Factor Correction (PFC) was used to completely eliminate surge noise.

Luxman M-900U (M900U) Power Amplifier
|
|
The M-900u has been created to bring out the best sound expression from your speaker system. 4 parallel push-pull structural output units have been connected together for a sound quality both rich in high tones with a deep bass sound. Luxman's original ODNF circuit has evolved overtime, now in version 4.0 creates a life like sound with ultra-low distortion. The large analog meter is and blasted white finish off the powerful amplifier with finesse. The BLT connection also allows the user to use the unit as an ultra-high power monaural amplifier of 600W (8Ω).

Linn Akurate Exaktbox-I - 8 Channel Exaktbox and Power Amplifier
|
|
Linn Akurate Exaktbox-1
Linn have repackaged Majik Exaktbox-I to become Akurate Exaktbox-I, giving it a new name and new case work. The addition of this product to the Akurate range gives customers the option to upgrade existing Akurate DS and Akurate DSM to Exakt with either integrated or separate amplification.
Intelligent digital crossover and DAC with integrated power amplifier
Upgrading your speakers to Exakt also means running them actively, so you'll need enough amps to dedicate a channel to every drive unit. With Akurate Exaktbox-I you can upgrade to Exakt with all the amplification
