5. Arcam Radia A25

Pros - revolutionary sound quality for its price group

The Arcam Radia A25 leaves no stone unturned from competitors in its price segment. 5th generation Class G design guarantees up to 100 W at 8 ohms or 165 W at 4 ohms load – and the sound of the amplifier is truly caressing to the ear, captivating with its naturalness, clarity and airiness. The USB DAC based on the ESS Sabre ES9280A Pro chip with support for digital streams up to DSD1024 is also “on board”, as is the phono preamplifier – so we have a fully finished device, to which we only need to add speakers and a source.

4. Audio Analogue AACento

Pros – beautiful presentation with excellent speaker control

The integrated amplifier Audio Analogue AACento in terms of sound is most similar to an iron fist in a velvet glove – it is genre-impartial and ready to cope even with complex speakers. The power rating is excellent, as is the attack, dynamics and bass control. The proprietary ideology of zero feedback both in the preamplification section and in the output stages, and a massive toroidal transformer with a power of 480 W guarantee record-breaking performance characteristics – for example, the output impedance does not exceed 0.4 Ohms, and the bandwidth extends to 100 kHz.

2. Devialet Astra

Pros – super-detailed sound picture

The update of the Devialet model range has been long awaited - well, Devialet Astra accumulates all the latest engineering solutions of the French company. Devialet Astra is capable of delivering 2 x 150 W of power when operating at a load with a nominal impedance of 8 Ohms and has full streaming capabilities. The proprietary patented ADH amplification technology of the latest generation ensures operation in the widest possible frequency range (the damping factor at a frequency of 1 kHz is 2,000, and the signal-to-noise ratio reaches 117 dB). In terms of detail and plasticity of delivery, the amplifier has few equals.

1. Burmester 232

Pros - exquisite sound with an accurate timbre picture

Burmester 232 is a "Swiss knife" for sound. In addition to a lot of functions, the model guarantees High End class sound - very beautiful, rich in textures and timbral authenticity. At an 8 Ohm load, the Burmester 232 integrated amplifier delivers 2 x 110 W, increasing to 150 W per channel when using 4 Ohm speakers, and distortion is extremely low (0.0048%). The model supports the installation of expansion boards with a DAC (with a streamer supporting TIDAL Connect, Spotify Connect, Roon Ready certificate and streaming via Wi-Fi) and Phono MC. Tactile feedback on the knob control (Burmester HaptiControl) is the icing on the cake.

    Understanding the Evolution of Audio Quality

    From Vinyl to Digital and Back to Analog Sound

    The development of the music industry in terms of formats was cyclical - the era of analog tapes and vinyl was followed by the era of the compact disc, then file formats, Hi-Res sound and, finally, streaming. However, today we can confidently say that in the highest echelon of quality the pendulum has swung back - and vinyl has become more alive than all the living again. Not to mention the revival of interest in magnetic tapes, compact cassettes - analog sound demonstrates such a luxurious sound that music lovers and audiophiles are ready to put up with the inevitable ergonomic limitations.

    How to Choose a Network Player in 2025

    When it comes to a modern Hi-Fi audio system based on a digital sound source, you can’t do without a network player or audio streamer, usually with a built-in digital-to-analog converter. These devices offer amazing flexibility of connection (both streaming clients of well-known services and wireless signal transmission options are “on board”), and their sound quality has advanced greatly in recent years. So much so that even relatively budget devices paired with an integrated Hi-Fi amplifier and acoustics can provide excellent sound quality. Our new rating or hit parade contains just such modern audio streamers.
