Burson Audio has introduced the Timekeeper Voyager mono power amplifiers, operating in Class AB and delivering up to 200 watts per channel into a 4 Ohm load. The Timekeeper series of amplifiers has been in development at Burson Audio for over fifteen years. The latest Voyager model is designed to operate at high idle current, allowing the transistors to operate in their most linear range, thereby minimizing distortion. Despite consuming over 100 Watts in standby mode, the Voyager achieves Class AB performance in a compact design, rivaling much larger amplifiers.

American company Audio Research has announced the start of sales of the flagship Reference 330M monophonic tube power amplifier, which was first announced last year. Audio Research Reference 330M is an amplifier that combines a new design and new components with the best solutions implemented in other amplifiers of the company. The creation of the device took a long period of development and as a result, the device was released, capable of developing up to 330 Watts of power.

TEAC has introduced the compact TEAC AP-507 two-channel power amplifier, which implements the latest Hypex NCOREx Class D technology. Compared to its predecessor AP-505, the TEAC AP-507 is equipped with an updated amplifier module with higher output power and low distortion. In addition, the TEAC AP-507 amplifier supports bridge mode for use as a powerful monoblock.

The American manufacturer of High-End audio equipment, Boulder, has introduced a new stereo power amplifier, the Boulder 1162. The model offers 2 x 300 watts of power into 8 ohm speakers and a staggering 2 x 900 watts into 4 ohm load.

Pro-Ject has introduced a compact stereo power amplifier Pro-Ject Amp Box RS2. A distinctive feature of the new product is the use of a pair of vacuum tubes and the ability to switch the model to a bridged mode.

The flagship High End power amplifiers from Constellation Audio, the Statement Mono Amplifier and Statement Stereo Amplifier, use a whole clip of the company's innovations and provide outstanding sound quality.

Fezz Audio has introduced the Fezz Olympia Mono Power Amplifier and the Fezz Olympia Dual Mono Amplifier. The models are based on KT88 tubes and offer high output power.

SMSL has introduced the SMSL PA200 stereo power amplifier – offering both volume control and switching to bridge mode. Thus, with one signal source, the owner can save on preamplifiers, and in the case of creating a multi-component installation, easily switch the system to monoblock amplification mode.

Greek company Lab12 has released the Lab12 Mighty tube power amplifier, operating in class A and providing an output power of 2 x 10 W. The model is compatible with both the Lab12 Hpa and True branded preamplifiers, as well as with a wide range of preamplifiers from other manufacturers.

The Japanese company Air Tight has presented the latest revision of its famous amplifier Air Tight ATM-1 (the first device was released in 1986, and in 2006 a more advanced version ATM-1s was released). The amplifier uses a push-pull circuit on 1/12AT7 (ECC81), 2/6CG7 (6FQ7) and 4/EL34 tubes.

Japanese manufacturer of High End electronics, Soulnote presented a stereo (2 x 120 W at 4 Ohms) power amplifier A-3core, which implements the concept of "dual mono". Each channel of amplification is powered by a separate toroidal 700 W transformer.

Following the Reference Preamp, the Swiss company Nagra has introduced the Nagra Reference AMP monoblock power amplifiers. The model replaces the well-known Nagra HD AMP and boasts a 25% larger power supply with 2000 VA transformers.

Dividing amplification circuits into a preamplifier and a power amplifier is one of the main cornerstones of High End audio. Such installations offer the highest possible quality due to the isolation of critical signal transmission circuits and the use of independent power supplies - but they also conceal a lot of pitfalls and possible errors in the pairing of components. In this article, we will try to highlight the main critical points of such a selection of equipment and highlight the most important specifications of amplification equipment that you should pay attention to when choosing.
