It's KEF LS50 Wireless! Bravo! The "active" version of renowned KEF LS50 with 4 Wolfson WM8740E DAC (two on one side)(side-note: 24bit 192khz playback, no native DSD playback supported, to play a DSD file, you need to convert DSD to PCM format(i.e. software decoding)See below:
Windows: usb dac- foobar2000;
MacOS: usb dac- Audirvana Plus;
Android: dlna playback-local music: Neutron Music Player, cloud music(Qobuz or Tidal): BubbleUPnP),
AMP and DSP, wifi(2.4g and 5g), bluetooth, RCA input, Toslink input, USB type B port......etc, all these new hardware and software with just HKD$10000 more (less than USD$1300)

Mysterious!




The Ports(Back of the right KEF LS50 Wireless)

The uni-q driver is so sexy!
So, you know the speaker requires more than 500 hours of burn-in time(the uni-q driver, dac and amp). So, how do I "skip" the burn-in time and enjoy the great music?

I pair the KEF LS50 Wireless with my cheap but great DAC and AMP:
Chord Mojo
Nobsound MS-10D MK ii (with Russian 6H1n tubes and Russian 6n1n-EB tubes)
Cable: 1.Labkable Acoustic Revive PC triple C 3.5mm male to RCA male cable
2. Moon Audio Silver Dragon USB cable
Both of them are of high CP values.(Well, I am so poor that I cannot buy a desktop DAC or desktop pre-AMP or desktop AMP or desktop integrated AMP)


No extra money to buy a SACD player or CD player......so I use my old blu-ray player

Another angle of the speaker. Oh, the uni-q driver is so handsome!

Aux input

Optical Toslink input

USB input

Wifi(use it with "LS50 Wireless" app, with this app, you can configure speaker distance from edge of the desk, distance from the speaker to the wall, level of bass extension,.etc. Thus, you can tailor-make your KEF sound!)(Again, android-dlna playback:local music: Neutron Music Player, cloud music(Qobuz or Tidal): BubbleUPnP))

Bluetooth aptx (There is no aptx HD codec with this speaker. This is a flagship bookshelf speaker, right? Hope KEF adds aptx HD or LDAC in the next generation LS50.)
