Leak Stereo 230 Integrated Amplifier
Firmly re-established as a Hi-Fi mainstay, the LEAK product portfolio is expanding with the new LEAK STEREO 230 – a high-performance, high fidelity integrated amplifier designed for the modern-day audio and movie enthusiast.
Building upon the class and style that made the STEREO 130 a rip-roaring success, the LEAK STEREO 230 adds more power, more functionality and more substance for the discerning audiophile.
Designed to be the perfect match for a wide variety of sources and provide higher levels of amplification, the LEAK STEREO 230 offers a 115w per channel output.
It also offers a newly developed HDMI ARC connectivity function to realise the highest quality audio in AV applications, making a fully equipped integrated amplifier ideal for meeting the demands of modern audiophiles and cinephiles.
The LEAK STEREO 230 can be connected to a wide range of analogue and digital sources, thanks to its diverse range of inputs. A built-in Moving Magnet (MM) phono pre-amplifier allows for direct connection to turntable record players.
To fully accommodate the modern-day music enthusiast, much effort has been made to ensure the LEAK STEREO 230’s digital circuitry delivers the level of quality one might expect of a high-performance standalone D/A converter, let alone an integrated amplifier solution.
You can also stream music to the LEAK STEREO 230 from any Bluetooth device, such as portable music players, tablet PCs or smartphones, via the built-in aptX and AAC Bluetooth codec. One can therefore enjoy CD-quality audio over the Bluetooth wireless connection.
Carefully designed in line with the LEAK ethos of performance, reliability and craftsmanship, the LEAK STEREO 230 matches contemporary performance with stand-out, classic LEAK styling.
The Leak Stereo 230 is a top-of-the-line integrated amplifier that delivers high-performance sound and style. With 115 watts per channel and a range of input options, it’s perfect for modern audio and movie enthusiasts. The Stereo 230 also boasts a newly developed HDMI ARC function for top-quality audio in AV applications.
Connect your turntable, digital sources, or stream music via Bluetooth with the Stereo 230’s built-in phono pre-amplifier and aptX and AAC codecs. We’ve made sure the digital circuitry in this amplifier delivers the same level of quality you’d expect from a standalone D/A converter.
In addition to its excellent performance, the Stereo 230 is designed with reliability and craftsmanship in mind. It combines contemporary performance with classic Leak styling to make it a standout piece in any setup.
