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.

Stealth Acoustics SA2400 - 2 Channel Amplifier
|
|
The Stealth Acoustics SA2400 is high-current two-channel amplifier with powerful built-in digital signal processing functions suitable as a low distortion power source for Stealth Acoustics speakers, Stealth subwoofers, or other un-powered speakers and subwoofers. Intended for distributed audio, fixed installations, or home theater applications, the SA2400 mounts using the supplied removable rack ears in a standard 19” (482 mm) equipment rack requiring only two RU spaces (3-1/2” – 89 mm), or may stack with other free-standing components. The SA2400 delivers a solid 310 watts per-channel into an 8Ω load and 450 watts per-channel into 4Ω.

Sonance Sonamp ASAP3D-SE (ASAP3DSE) - 2 channel rack mount amplifier
|
|
The ASAP3D SE combines the latest digital power amplifier technology with proven Sonamp® auto House/Local source switching and BBE® Sound Enhancement in a new small package that dramatically expands your installation options. Featuring a highly efficient ICEpower® digital amplifier that provides 25W RMS/ch @ 8 ohms and 50W RMS/ch @ 4 ohms with very little heat generation, the ASAP3D SE is housed in a 1U high by ½-rack wide package. This allows you to mount the amplifier almost anywhere (a key-hole on the bottom panel even lets you hang it on a wall behind a flat screen TV), improves its long-term reliability and provides significant energy savings over conventional amplifier designs. (ICEpower was developed by B and O, a company known for high-quality sound.)

Jadis SE300B Amplifier
|
|
The SE300B supplies a power of 10W RMS and functions in pure class-A with single-ended mounting (the two tubes are in parallel) with an automatic bias. The two high voltages, driver and power, have vacuum-tube power supplies. The bandwidth (at –3dB) is from 20Hz to 20kHz, without any feedback. The driver stage, powered at 400V, is built around a double-triode 6SN7. The two elements of the tube are mounted in cascade. The output stage is powered at 320V, which allows the tubes to work in the best conditions.

Jadis SE845 Amplifier
|
|
The SE 845 design is in response to the demands for natural and dynamic musicality and the technical choices for this amplifierhave been made with this requirement in mind. For the 845 triode to be effective, it needs an incoming signal of high amplitude under low impedance : The ECC 83 double triode ensures the gain in tension, while the 6SN7 ensures the impedance adaptation between the driver stage and the power stage.

Jadis JA120 Amplifier
|
|
These amplifiers work in "push-pull" configuration, triples load and autobias.
They can work with various types of penthodes: KT120, KT90, KT88, 6550, 6CA7 or EL34.
The function phase shifter is assured by a triode double ECC82 and the function driver by an ECC83. It can work in symmetric mode on option.The output transformers, guaranteed for life, allow an adaptation of impedance from 1 to 16 ohms.

Krell Solo 575 XD (575XD) Mono Power Amplifier
|
|
Krell Solo 575XD
Mono Amplifiers
Krell's New XD Technology
Krell’s “XD” (Xtended Dynamics, Xtended Dimensionality, Xtended Detail) upgrade for the iBias amplifiers takes an already great sounding amplifier and raises its performance to the next level. “XD” is a classic example of Krell’s continuous R & D efforts reaping benefits across multiple product lines. During the development of the K-300i Integrated 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 so substantial that it required a unique designation, hence, “XD.”
