Hotel Revolution

With a wealth of entertainment options delivered in true audiophile resolution, explore the local jazz scene, reconnect with the classics, or take in a show live from your living room, every night! Welcome to Hotel Revolution: check out anytime you like.



With inbuilt and ready-to-play music functionality, complimentary speaker cable, and an easy-to-follow setup instruction video, this first-class ticket to weeknight wanderlust includes everything you need to play straight from the box.


We combined Wharfedale’s EVO4.2 bookshelf loudspeakers with Audiolab’s OMNIA all-in-one streaming amplifier to create a complete music system with advanced technological features and audiophile-grade sound quality. This is not entertainment; this is escape.



Omnia is an amplifier, yes. But also, a wireless multi-room streamer, a CD player, a Bluetooth player, and headphone amp. Combined with its vast range of digital and analogue inputs, the Hotel Revolution entertainment roster is incredibly broad.


Music through a high quality 32-bit DAC is like seeing colour for the first time. And with Omnia’s ES9038Q2M SABRE Reference DAC, you’ll enjoy a rich pallet of breath-taking sounds that place musicians in the room with you.



With onboard DTS Play-FI, access all your favourite streaming services like Spotify, Tidal, Deezer, Amazon Music & more. Plus, Play-Fi’s easy-to-use app for both iOS and Android smart devices gives you palm-sized control over the evening’s entertainment.


AMT (Air Motion Transformer) technology is a revolutionary approach to high-frequency reproduction. Highly musical with naturally low distortion, EVO4 plumbs the depths of every track you play to recover detail other speakers leave far behind.



Sophisticated computer modelling, hundreds of hours of listening, and the highest quality components ensure that EVO4 drivers fire in unison. The technical results are phase consistency and a linear frequency response, but all you hear is perfect harmony.


EVOs remarkable efficiency means greater wow factor for less watts. So, when paired with OMNIA’s 50W of class A/B amplification, instruments have real texture and vocal notes hang in the air with haunting sustain. In short, you’re drawn into a vivid listening experience that offers true escape.
