The KEF LSX Wireless Music System Is Now Out!

KEF just launched LSX wireless music system with all the convenience of connectivity and true high-resolution stereo. How will the KEF LSX wireless music system improve your music? Read on to find out more!


What is KEF LSX?

The KEF LSX is fully wireless from both source and between the speakers. It features Apple AirPlay 2 technology that enables multi-room streaming from an iPhone, iPad or Mac (in early 2019).

After the success of the LS50 Wireless, the KEF LSX features their Uni-Q driver array, that radically improves stereo imaging across a much wider listening area allowing more people toexperience better sound.

The KEF LSX combines with KEF’s highly advanced trademark-pending Music Integrity Engine, a cutting-edge collection of bespoke Digital Signal Processing algorithms, ensuring accurate time alignment and phase coherence.


What Can  The KEF LSX Do?

The KEF LSX is fully wireless both from source and between the speakers, using Wi-Fi and Bluetooth to stream music from Spotify, Apple Music and TIDAL. LSX is also DLNA compliant and boasts TOSLINK Optical and Auxiliary connections, making it ideal for use with TV. It can be set-up in minutes using the KEF’s Control app, which also manages firmware updates as they become available.

The KEF LSX sports four Class-D amplifiers, one for each of the drive units alongside dedicated twin DACs that provide pristine signal path of up to 96kHz/24bit (using the optional wired connection between the two speakers) or 48kHz/24bit in completely wireless operation.

>LSX’s gently curved cabinet was designed with extensive use of Finite Element Analysis as well as  constrained layer damping as found in KEF’s high-end audiophile products.LSX was designed by designer Michael Young who has created a masterpiece of understated elegance and comes in a choice of five colours – Black, Blue, Maroon, and Olive. They are clad in a luxury fabric by Danish textile manufacturer Kvadrat – and a striking Gloss White.

With Spotify Connect (available in November 2018) built in, music lovers can stream Spotify’s entire library directly from the cloud. Uninterrupted streaming lets users watch videos, play games, answer phone calls without pauses to the music even as the listener leaves the room or goes out of range.

LSX goes on sale on 12 November 2018 at selected retailers with a recommended retail price (RRP) of RM 5,999 / ~US$ 1,429.

The Sony Signature Series Audio Technology Explained

At the recently-held Sony Sound Stage 2016 event, Sony took the opportunity to introduce their new Sony Signature Series premium audio products. They even brought in Sony’s Chief Sound Architect, Koji Nageno, to explain the technologies behind the Sony Signature Series models.


The Sony Signature Series

The Sony Signature Series was created, partly to showcase Sony’s engineering excellence in audio, and partly to celebrate their 70th anniversary. Combining High Resolution Audio capability with the very best Sony analogy and digital audio technologies, Sony designed the Sony Signature Series products to deliver the ultimate in sound quality.

The first four Sony Signature Series devices to be introduced are the Sony MDR-Z1R headphones, the Sony NW-WM1Z and NW-WM1A Walkman audio players, and the Sony TA-ZH1ES headphone amplifier. All Signature Series models are based on the newly standardised φ4.4mm balanced connection.

Sony MDR-Z1R Headphones

The MDR-Z1R headphones boast 70mm HD drivers that have a wide frequency range with up to 120kHz playback in High Resolution Audio. Its equalised opening and resonance-free housing further ensures faithful reproduction of High Resolution Audio sources.

It is fitted with genuine leather ear pads, a lightweight beta titanium headband, and a stainless steel wire mesh housing protector. This is no doubt, an exquisite product that exudes luxury in every component.

Sony NW-WM1Z & NW-WM1A Walkman Hi-Res Audio Players

Both Hi-Res Audio players support the DSD Native format (11.2 MHz), and the new Digital Sound Enhancement Engine (DSEE HX) technology that upscales lower bit rate files to near Hi-Res Audio quality. They also add a newly-developed FT CAP to the amplifier, allowing for 4x higher power output to the headphones.

The higher-end NW-WM1Z comes with a gold-plated oxygen-free copper chassis, while the NW-WM1A comes with a sleek aluminium chassis.

Sony TA-ZH1ES Headphone Amplifier

The Sony TA-ZH1ES headphone amplifier supports Hi-Res Audio up to 22.4 MHz (DSD) and 768 GHz, 32-bit (PCM), and comes with the D.A. Hybrid Amplifier Circuit – a combination of the S-Master HX digital amplifier and an analog amplifier. It also features the new DSEE HX and DSD Remastering Engine, which converts lower bit rate files to near Hi-Res Audio quality.
