LEAK Stereo 230 is a stereo integrated amplifier that replaces a preamplifier, DAC, phono stage, and headphone amplifier in one unit. It suits turntable-based systems, Bluetooth streaming, and TV audio via HDMI ARC, removing the need for separate components at each source. The built-in ES9038 DAC supports up to DSD512 over USB, and the dedicated headphone circuit drives loads from 16 to 600 ohms. Classic LEAK styling gives it a visual identity that separates it from generic black-box alternatives.

Product Details

Who is the LEAK Stereo 230 for, and what sets it apart?

Is the LEAK Stereo 230 a genuine all-in-one solution or a compromise?

The LEAK Stereo 230 is a fully integrated amplifier that combines a moving magnet phono stage, a high-resolution DAC, Bluetooth streaming, HDMI ARC, and a dedicated headphone amplifier within a single chassis. Buyers who'd otherwise need a separate phono preamplifier, a standalone DAC, and a headphone amplifier will find that this integrated unit removes those additional components and their associated cabling. The amplifier section delivers 75W per channel into 8 ohms and 115W per channel into 4 ohms, making it suitable for a wide range of loudspeaker loads.

Where does it sit within the LEAK range and wider market?

The LEAK Stereo 230 is the brand's flagship integrated amplifier and carries the LEAK design philosophy of performance, reliability, and craftsmanship into a contemporary specification. Buyers will find the Stereo 230 differentiated by its certified hardware MQA Full Decoder, its ES9038Q2M DAC chip, its aptX and aptX LL Bluetooth codec support, and its current-feedback headphone amplifier. Those who already own a turntable with a moving magnet cartridge, stream from a phone or tablet, and want to connect a television via HDMI ARC will cover all of those use cases from this one unit without adding source components.

What sources can the LEAK Stereo 230 connect to?

Does the LEAK Stereo 230 support vinyl playback without an external phono stage?

The LEAK Stereo 230 is equipped with a built-in moving magnet phono preamplifier, so owners of turntables fitted with MM cartridges can connect directly without an outboard stage. The JFET-based circuit applies RIAA equalisation in accordance with the industry standard for vinyl playback, ensuring correct frequency balance from the stylus through to the amplifier. The 47kΩ input impedance with 100pF capacitance loading matches the standard electrical requirements of moving magnet cartridges. The signal-to-noise ratio of the phono stage exceeds 75dB (A-weighted).

What digital sources and file formats does it accept?

The LEAK Stereo 230 is built around the ES9038Q2M DAC, which uses ESS Technology's 32-bit HyperStream architecture and a Time Domain Jitter Eliminator. Jitter — timing irregularities in a digital signal — degrades the accuracy of digital-to-analogue conversion; the on-chip jitter elimination circuitry addresses this at the source before conversion occurs. Via optical and coaxial S/PDIF inputs, the unit accepts PCM up to 192kHz. Via the PC USB input (USB-B), it handles PCM up to 768kHz as well as DSD64, DSD128, DSD256, and DSD512, making it compatible with high-resolution audio files from a computer-based playback system. The DAC's signal-to-noise ratio exceeds 115dB (A-weighted).

Does it support MQA decoding?

The LEAK Stereo 230 is a certified hardware MQA Full Decoder. MQA (Master Quality Authenticated) is an audio format that encodes studio master recordings; full hardware decoding means the unit handles the complete decode process internally rather than relying on software processing upstream. This applies via the PC USB, coaxial, and optical inputs, so hardware MQA decoding is available from both computer and disc-transport sources.

Can it stream wirelessly from a phone or tablet?

The LEAK Stereo 230 is Bluetooth 5.0 compatible and supports both aptX and aptX Low Latency codecs. AptX delivers CD-quality audio over a Bluetooth connection, meaning the wireless path doesn't introduce the audible data reduction associated with standard SBC Bluetooth. AptX LL reduces transmission latency, which matters when synchronising audio with video content played from a mobile device. Any Bluetooth device — smartphone, tablet, or portable music player — that supports these codecs can stream to the Stereo 230 without a physical connection.

Does it integrate with a television or home cinema system?

The LEAK Stereo 230 is fitted with an HDMI ARC (Audio Return Channel) input. ARC allows a compatible television to send audio back down the same HDMI cable used for video, removing the need for a separate audio cable between the TV and the amplifier. This lets the Stereo 230 function as the audio output device for a television while retaining all its hi-fi source inputs. Buyers building a combined hi-fi and AV setup around a single amplifier will find this the key compatibility feature.

What analogue line-level sources can connect to it?

The LEAK Stereo 230 accepts two analogue line-level inputs alongside the phono input, covering CD players or any analogue source with a standard line output. The unit also provides a 12V trigger input and output, allowing it to power on and off in sequence with compatible source components or processors in an integrated system.

How does the amplifier handle different speakers and headphones?

What loudspeakers is the Stereo 230 compatible with?

The LEAK Stereo 230 is a Class AB amplifier using ST MOSFET TDA7293 devices in a dual parallel configuration. The rated output is 75W per channel into 8 ohms and 115W per channel into 4 ohms. The frequency response across the power amplifier section holds within ±0.3dB from 20Hz to 20kHz, and total harmonic distortion measures below 0.003% at 1kHz and 30W into 8 ohms.

Is the headphone output a secondary feature or a properly specified circuit?

The headphone amplifier in the LEAK Stereo 230 is a discrete circuit using current-feedback topology, separate from the main amplifier stage. Current-feedback amplifiers achieve a high slew rate — the speed at which the output voltage can change — producing high-speed output signal transition. The output impedance is 4.7 ohms and the compatible load range is 16 to 600 ohms. THD at 1kHz and 50mW measures below 0.01%.
