The most interesting hi-fi (and head-fi) news stories for week 32, 2022.
German headphone manufacturer Sennheiser has announced the fourth version of its Momentum Wireless over-ear Bluetooth headphones. Thanks to a “2 × 2 beamforming mic array” and better wind noise reduction, the Momentum 4 Wireless promises improved active noise reduction over the previous version. And taking a leaf out of the Bowers & Wilkins headphone book, Sennheiser has turned the (4.2cm) driver inside each earcup towards the ear. However, unlike the B&W PX7 S2, the right Sennheiser earcup offers touch-sensitive control of transparency mode and phone calls (and presumably play/pause). The partnering SmartControl smartphone app offers EQ and a sound personalization function that will probably put the devil in the details. Perhaps most important of all, the Momentum 4 Wireless offers a whopping 60 hours of playtime from a single charge—double that of the Sony WH-1000XM5 and the aforementioned Bowers—with a ten-minute quick charge yielding 6 hours of playtime. These new noise cancellers support aptX Adaptive, aptX, AAC and SBC Bluetooth codecs and go on sale later this month for US$350/€350 (which is a bit cheaper than the version 3 model and Sony’s current flagship).
Lost has announced the T3: a high-end streaming DAC that marries a dual mono circuit – built around a pair of ESS ES9028Pro chips – with a Leedh lossless volume control and puts it in a slim and stylish (my words) aluminum chassis which, according to Lumin, is less susceptible to fingerprints. Your choice of silver or black. D/A conversion supports PCM up to 384kHz and DSD up to DSD512 with single ended and balanced outputs provided. USB and BNC digital outputs also appear to handle optional connections to an external DAC. On the Ethernet-powered streaming front, the T3 will play local files and Qobuz streams from Lumin’s UPnP / OpenHome-enabled smartphone app (iOS and Android), but it also supports Roon Ready, Spotify Connect, Tidal Connect (with MQA) and Apple AirPlay. The T3 starts shipping in September and will sell for €4990.
High-end Japanese manufacturer Luxman is starting its centenary three years early with the announcement of a new integrated amplifier. The L-507Z is the first member of a new “Generation Z Series” and features the V1.0 LIFES feedback engine which is said to aim to minimize distortion. Also on board is a new 88-step electronically controlled volume attenuator – called the LECUA1000 – which promises greater transparency over a wider range of volume levels. A custom wound EL type transformer and the associated power supply help to deliver 110wpc into 8 Ohms, 210wpc into 4 Ohms, all with suitable peak power delivery and a damping factor of 300. an asking price of £8000 / €9490. The L507Z starts later to ship this month.
