That brings us to the LS50 Wireless II’s all-new streaming platform that carries with it Bluetooth (AAC but no aptX or LDAC), Apple AirPlay 2, proper Roon Readiness* (hello RAAT & multi-room sync), Spotify Connect and Google Chromecast Built-in to complete this commentator’s Holy Trinity of Streaming. Will MQA’s 44.1kHz/48kHz travel formats be unpacked entirely by the primary loudspeaker before being channel separated? Or will left and right channels be separated and then unpacked by their respective loudspeakers? Or will the primary speaker copy the stereo stream to the secondary speaker and then each speaker drops the channel that it doesn’t need? However, at the time of writing, it is unclear if those streams will be limited by the wired or wireless interlinks. The LS50 Wireless II will also support MQA in full: decoder and renderer. Everything streamed above the chosen interlink’s capabilities will be downsampled accordingly Not mentioned in the press release: the interlink’s maximum sample rate capabilities impose a glass ceiling on listeners looking to max out the LS50 Wireless II’s hi-res streaming support: PCM up to 384kHz and DSD256. Best amp to drive KEF ls50 meta By Marco79 Main Stereo Amplifiers & Pre-Amps Share Followers 3 2 Next of 2 Marco79 Member 210 Region: Australia Location: Sydney First Name: Marco Posted MaHi guys I need advice for a right-sized amp to drive some kef meta. And anyone pulling the LS50 Wireless II out of standby with a network stream can expect a five-second delay before the secondary speaker is woken by the primary when wirelessly interlinked. Whilst we’re talking language, those hanging their hat ‘Wireless’ are advised that the LS50 WII’s Ethernet-based 24bit/192kHz interlink is now optional - a 24bit/96kHz wireless interlink is also possible. KEF has given the outmoded ‘master/slave’ terminology the boot. (I’ve always found the LS50 to be too much loudspeaker for a desk). KEF is likely betting that more people will put the LS50 Wireless II either side of a TV set than they will a desktop monitor. On hard-wired connectivity, we note two changes, one significant, the other less so: coaxial and TOSLINK remain but 1) the twin RCAs have been substituted by a 3.5mm analogue input and 2) the USB has been swapped out for HDMI ARC. One upshot is 7Hz greater bass depth the LS50 is rated by KEF down to 47Hz but the LS50 Wireless II down to 40Hz. The LS50 Wireless II then activates the LS50 Meta’s 12th Generation + MAT Uni-Q driver array with a DSP crossover dividing the signal between the mid-bass driver’s new 280 Watt Class D amplifier and the tweeter’s new 100 Watt Class A/B amplifier. The LS50 Meta will be available in four matte finishes – Carbon Black, Titanium Grey, Mineral White plus a Royal Blue Special Edition – and will sell for £1000/€1199/US$1499 per pair. Room correction (like SVS 2000 series, ELAC.) if your amp doesn't have that, as rooms are inherently messy in the bass.Īll that said, no reason not to just hook them up to the Marantz you have and see how you like it, that's so easy.For its Meta iteration, KEF has elevated the LS50’s Uni-Q driver to a 12th Generation design that sports a ‘new cone neck decoupler’ and motor system plus the ‘tweeter gap dampener’ first introduced in the 2018 R Series.Īlso inside the cabinet, the LS50 Meta receives an ‘off-set flexible bass port’ designed to reduce midrange colouration and more rigid cross bracing with constrained layer damping. You can step up to more power (300 watts RMS at least, 500W better). when people discuss a budget, the recommendation is to go for a used model, which is something i would also like to avoid if possible (not. if i had 5,000 to invest in a my rig, then frankly i would not be going for the LS50's. Subs run a big gamut-this $85 Christmas present for my brother Monoprice 12in 150-Watt Powered Subwoofer, Black - is nicely filling in his bottom end though it's not gonna break his windows. most of the recommendations i am seeing are for amplifier setups costing several thousand plus. There was another recent thread where some LS50 owners were singing the praises of how much a sub opened up their LS50s. I think that's why some folks recommend a lot of power-to turn them up so the bass is more audible versus our hearing curve. That plus a sub would really fill in the low end my opinion hearing the LS50s was nice but no truly low bass.
