The Current feedback amplification topology and powerful power supply of the A-48S amplifier provides a large reserve and stable output in pure Class A. For a load with an impedance of 8 ohms, 50 watts are available, and halving the load impedance doubles the output power. With a short-term drop in load impedance to 1 ohm, the amplifier is capable of delivering a power of 400 watts.

The excellent Akurate power amplifier features 4 channels with balanced or RCA connectors. Silent, dynamic, and highly efficient, Akurate amplifiers can effortlessly pump through even the most demanding music, delivering loud, complex passages and quiet interludes with equal precision.

The Switch Mode Power Supply audio optimization technology used in Akurate power amplifiers ensures a more stable and interference-free power supply compared to conventional power sources. The device with three channels is capable of producing 200 watts with a impedance of 4 ohms.

A model with a high-quality distortion-free amplifier, each channel of which is equipped with an innovative Dynamik Switch Mode power supply and 200W of patented Chakra technology. So regardless of the system settings, whether it's stereo, multi-channel or active mode, you can enjoy high quality, without distortion.

limax Twin is a stereo version of the famous Linn tip. We have already written about its monoblock "ancestor" Klimax Solo: the novelty inherited its parameters, but was able to accommodate twice the electronic stuffing in a body of the same size, by the way, on a milled aluminum chassis. Recall that we are talking about a 200-watt amplifier (now x2) with a 4-ohm load and a coefficient of nonlinear distortion of at least 0.02%. The frequency range is 7 Hz - 35 kHz.

The operating range of the Cyrus Classic POWER amplifier extends from an almost constant voltage to a frequency above 50 kHz. The novelty is equipped with both unbalanced (RCA) and balanced (XLR) inputs, a 12V trigger input, a proprietary MC-BUS control bus connector, a connector for connecting an optional Cyrus PSX-R2 external power supply and a USB port for firmware updates.

The Cyrus Power-XR broadband power amplifier develops 110 watts when operating on a load with a nominal resistance of 6 ohms in each of the two channels. At the same time, the operating range of the new product extends from almost constant voltage to a frequency exceeding 100 kHz. The amplifier is equipped with both unbalanced and balanced inputs, a 12V trigger input, a proprietary MC-BUS control bus and a connector for connecting an optional Cyrus PSU-XR external power supply.

The model is equipped with a balanced XLR input and an unbalanced RCA input, which is duplicated by a similar RCA output. On the back panel there is a slider selector switch that allows you to select the desired pair of connectors (RCA or XLR), as well as switches for selecting one of the gain values (25 dB or 31 dB) and for activating one of the operating modes: stereo, bridge mode or "dual mono".

The Arcam PA720 is a seven—channel power amplifier from the proprietary HDA series. It works in class G, outputs 7 x 140 watts, 5 x 175 watts or 2 x 225 watts, while the first 20 watts of the device works in pure class A.

The amplifier develops a power of 4 x 50 Watts at 8 ohms in the AB class and is designed mainly for voicing the upper channels when operating in 7.1.4 Dolby Atmos and DTS systems.:X or Auro-3D, although it can be successfully integrated into a multi-room audio system.

A high power iBias technology stereo power amplifier DUO 300 XD offers Class A sound quality while maintaining efficiency. Advanced cooling system guarantees flexibility of use.

With dual GhostMeters in front of the eight output power tubes Reference 160S uses proprietary auto-bias circuit, switchable Triode or Ultralinear modes of operation, and a four-layer circuit board. Tubes included 4 x matched pair KT150, and 4 x 6H30.

Boulder 1162 offers 2 x 300 Watts of output power, newly developed protection circuitry and 32 Amp IEC pre-terminated power cord - before us is a mighty device.

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

The Pro-Ject Amp Box RS2 power amplifier is built using a hybrid scheme - the preliminary amplification stage in each channel is implemented on a dual triode 6922 (6DJ8). The solid-state output stages operate in the traditional class A/B and provide up to 80 W in each channel when working on a load with a impedance of 8 Ohms and 130 W for a load of 4 Ohms. In bridge mode, the amplifier is capable of developing up to 350 W.

Balanced Bridged technology stereo power amplifier with Line Stage Gain Module input stage, Switched-Mode Power Supply (C-SMPS) and Power Factor Correction (PFC) technology. Max power rating offers 2 x 300 W into 8 Ohms load.

PFC perfectly stable, 380-volt power supply automatically optimizes itself for any speaker and AC power standard - so, Statement Stereo Amplifier can deliver 2 x 850 W into 8 Ohms load and 1,600 W into 4 Ohms.

The Onkyo Icon M-80 power amplifier delivers 2 x 200 W of power when driving speakers with an impedance of 4 Ohms and 2 x 150 W for speakers with an impedance of 8 Ohms. The amplifier is made in a fully balanced configuration with output stages operating in class A/B.

Lab12 Mighty is compatible with EL34, 6550, KT88 output tubes (EL34 from the factory), does not use feedback and has a triode/ultralinear mode switch. The preamp is also equipped with Nissei analog volume meters.

The output stages of the SMSL PA200 use Infineon GaN FET transistors, providing power up to 160 W for each of the two channels when operating on a load with a nominal resistance of 4 Ohms or up to 400 W at 4 Ohms in bridge mode. Harmonic distortion remains at a level of only 0.003%.
