The Degritter Mk.II Ultrasonic Cleaner, an upgrade from its predecessor, boasts a series of technological improvements designed to enhance vinyl cleaning. The new model introduces a pulsating ultrasonic process that shifts in power and frequency for better cleaning. It also features hardware transducers with smaller frequency sweeps, which allows for more intensive cleaning while being more energy-efficient. Additionally, the Mk.II is equipped with improved fault detection for quicker repairs and an upgraded water pump to reduce foam, which prevents potential damage to vinyl labels. During testing, the reviewer appreciated the ability to disable the pre-soak feature using a beta version of the software, as pre-soaking can wash off surfactants added directly to the vinyl, reducing cleaning efficiency. When testing the sound quality of cleaned vinyls, the reviewer found significant sonic improvements in the Mk.II over the Mk.I, especially in bass quality, mid-range, and treble clarity. While the Mk.I remains a top-notch cleaner, the enhancements in the Mk.II are both impressive and startling. Priced at £2,550, the Degritter Mk.II is highly recommended for those who prioritize vinyl cleaning and is regarded by the reviewer as the pinnacle of vinyl cleaning technology. Read more

AV Quick Takes: Sony Acquires Headphone Maker Audeze


Sony Interactive Entertainment, a subsidiary of Sony Group Corporation focused on the PlayStation division, has acquired Audeze, a California-based premium headphone manufacturer. This acquisition aligns with Sony’s ambition to elevate audio experiences for PlayStation users and offers Audeze access to Sony’s extensive resources for product development. While the financial details remain confidential, the partnership aims to integrate Audeze’s expertise, especially in planar magnetic driver technology, into the PlayStation audio ecosystem.
