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.

Marantz MM7025 2 Channel Power Amp
|
|
The MM7025 is this year’s ideal two-channel main amplifier with a whopping 140W rms into 8 ohms per channel. Use it in an AV setup to give your front channels an earth-moving boost or simply to make a sensational upgrade to an existing stereo system. And, because the technology is the same as that in the MM7055 and MM8003 using them in combination is fast, efficient and friendly. It’s a great flexible customisation enabler. And, as with the big brother MM7055, it also includes a new stylish display, XLR inputs, DC triggers and Marantz bus.

Copland CTA 506 (CTA506) Valve Power Amplifier
|
|
The CTA506 power plant is based on the KT120 power valves. These valves are a new variant of the legendary 6550 / KT88 power valves. For more than half a century, these classic valves have been the foundation of numerous of high quality amplifiers and surely, they will continue to serve as one of the premium choices among manufactures of high-power valve amplifiers. However, nowadays KT120 is the most powerful dedicated audio tube in production. In comparison with the KT88, nearly 30% more power can be drawn from these impressive valves. With a plate dissipation rating of 60W, a pair of KT120 tubes in push-pull configuration can deliver nearly 200W of audio power. When used in circuit designs of more modest power outputs, the KT120 can deliver incredible quantity of headroom and dynamic without overloading.

ada PF-2502 Flag Ship 2-Channel Power Amp
|
|
The PF-2502 utilizes the same amplification modules as used ADA's heralded MPA-502 in conjunction with a power supply to support two channels. Both amplification modules and power supply reside in a single chassis. The PF-2502 can be added to an MPA-502 for seven channels of home theater power amplification. Alternately, the PF-2502 can also be used for sound reinforcement in a multi-room system or more basic two-channel audiophile stereo system.

ada MPA-502 Flag Ship 5-Channel Power Amp
|
|
The MPA-502 is an incredible five-channel power amplifier with an impressive heritage. Introduced as the MPA-500 in 1992, it became the power amplifier that was utilized to assist in writing THX's original amplifier specification. Based on an audiophile configuration, where a mammoth power supply resides in its own chassis (MPS-502) independent of the chassis housing the five amplifier modules, the MPA-502 is the most powerful multi-channel power amplifier in the world. In fact, when operating on a standard 115V AC outlet, you cannot even force the amplifier into clipping because to do so requires 28 amperes of wall current. The MPA-502 incorporates a 2500 Watt custom torroidal power supply in combination with 500,000µF of capacitance. This huge power reservoir ensures that the MPA-502 has plenty of punch for even the most dramatic scenes. Suffice it to say, that the MPA-502 is as good as it gets. For systems requiring back surround speakers (7.1), ADA provides the exact same amplifier modules in a two-channel version, the PF-2502.
