Amplifiers That Stood Out to Our Editors Worth Hearing

The Douk Audio P2 is a compact tube preamplifier that can sit between a source and either a power amplifier or powered speakers.

Its supplied 6K4 tubes can be replaced with several compatible alternatives, while socketed operational amplifiers provide another route for users interested in changing components.

Separate high-, mid- and bass-frequency controls broaden its appeal for listeners who prefer hands-on tonal adjustment. The P2 also functions as a headphone amplifier and can send signals through its RCA and 3.5 mm headphone outputs simultaneously. Bluetooth, USB storage and TF card playback make it more flexible than a conventional analog tube preamplifier, with listed file support including APE, FLAC, WAV and WMA.

The SPEC RSA-EX1000 is an integrated amplifier built around a redesigned main board and shorter internal wiring.

Its level-controller and low-pass-filter circuit has been optimized to reduce internal resistance and interference, while EMC paint, internal shielding and electromagnetic absorption sheets are used to improve isolation inside the chassis.

A 600VA R-core transformer anchors the power supply. The amplifier is specified to deliver a maximum of 200 watts per channel into 4 ohms and supports speakers with nominal impedances from 4 to 16 ohms. Two pairs of XLR inputs, three pairs of RCA inputs and an included remote control make it suitable for systems with several balanced and unbalanced sources. Maple side frames and a spruce-laminate chassis give the design a distinctive material identity.

The Lyngdorf TDAI-2210 combines integrated amplification, network playback and both analog and digital inputs.

Its True Digital Amplifier Integrated architecture keeps the signal in the digital domain through to the speaker terminals, with volume adjusted by changing gain in the output chain rather than by using a conventional analog volume circuit.

Rated output is 105 watts per channel into 8 ohms and 210 watts per channel into 4 ohms. Optional modules allow the system to be expanded, making the TDAI-2210 relevant to listeners who want a centralized digital and streaming hub without ruling out future additions.

The Monitor Audio Hyphn is the outlier in this amplifier-focused selection because it is a passive loudspeaker, not an amplifier.

Each enclosure stands almost 140 cm tall, weighs 106.9 kg and contains eleven drivers.

Its central midrange and high-frequency array forms the architectural link between two bass towers. A third-generation Micro Pleated Diaphragm tweeter is surrounded by six two-inch midrange drivers positioned closely together to approximate a point source and support broad dispersion. Four eight-inch woofers are installed inside the linked cabinets, while the stated overall frequency range extends from 18 Hz to 60 kHz. Amplifier buyers should treat the Hyphn as a possible system partner and investigate its full electrical requirements before choosing amplification.

Micromega’s M-Amp Solo combines retro-influenced styling with a dual-mono Class AB amplifier.

It delivers 85 watts per channel into 8 ohms and 105 watts per channel into 4 ohms, giving buyers concrete figures to compare against the requirements of their loudspeakers.

An ESS ES9280AQ PRO-based DAC handles digital sources, while the integrated moving-magnet phono stage allows a compatible turntable to be connected without a separate phono preamplifier. Streaming can be added through the optional Escape M1 Air module. A transparent plexiglass top panel exposes part of the internal construction and reinforces the amplifier’s visual character.

The NAD C 298 is a dedicated stereo power amplifier, so it requires a separate preamplifier, source with volume control or another suitable control component.

Purifi Eigentakt modules manufactured under licence by NAD provide a specified 185 watts per channel into 8 ohms and 340 watts per channel into 4 ohms, with peak output stated at more than 570 watts.

Balanced XLR and unbalanced RCA inputs are provided, with automatic signal detection and an adjustable activation threshold. An RCA line output can feed an additional amplifier or active subwoofer. The metal chassis is designed for passive airflow rather than active fan cooling, and each channel uses its own rectifier and filter capacitors.

The Avid Hifi Celsus Pre is a fully balanced analog preamplifier with no onboard DAC.

Inputs and outputs can use XLR or RCA connections, while the power supply occupies a separate enclosure to keep it away from the main signal circuitry.

Its built-in phono section is derived from Avid’s Pulsare II design. Front-panel adjustments operate relays so that the signal remains on the main circuit board, and connections are provided for two cartridges at once. A selectable mono function can help reduce distracting background noise when playing mono records. Buyers building an analog-focused system should remember that a separate power amplifier is still required.

The Denon PMA-800NE is a conventional integrated amplifier equipped for analog, digital and vinyl sources.

Its DAC accepts PCM signals up to 24-bit/192 kHz through three optical inputs and one coaxial input.

When analog mode is selected, the dedicated digital power supply and digital input circuit are switched off to limit high-frequency interference with the analog section. Front-panel facilities include a 6.3 mm headphone socket, speaker A and B selection, loudness, Source Direct, tone and balance controls. Denon’s Separated Signal Level Design assigns distinct layouts to the phono, preamplifier and power-amplifier circuits, while an anti-vibration metal chassis and aluminum front panel complete the construction.

The WiiM Vibelink Amp is an integrated Class D amplifier designed to work with external analog and digital sources.

Unlike several other WiiM products, it does not contain a streaming platform.

That distinction makes it a logical companion for a separate network streamer rather than an all-in-one streaming amplifier. Its output is specified at 100 watts per channel into 8 ohms and 200 watts per channel into 4 ohms. One RCA analog input is joined by coaxial and optical S/PDIF inputs, with an ESS 9038Q2M DAC supporting signals up to 24-bit/192 kHz. Thermal management combines a copper heat pipe, an aluminum radiator and active operating-parameter monitoring.

The Vincent SA-32 AE is a limited-edition hybrid stereo preamplifier, with production restricted to 200 units.

It expands the digital connectivity of the underlying SA-32 design by adding HDMI ARC alongside Bluetooth, coaxial and optical inputs.

HDMI ARC is particularly useful for routing television sound through a dedicated hi-fi system without a separate adapter. Its revised tube complement comprises two 12AU7 and two ECC88 valves. The 12AU7 pair follows the inputs at the front of the signal path, while the ECC88 pair operates in the tone-control stage as phase splitters. As a preamplifier, the SA-32 AE must be partnered with a separate power amplifier or suitable active speakers.
