The Cary Audio AiOS (All-in-One-System) ($2,995)


From Cary Audio:

AiOS is a new kind of music system for a new generation. What does that mean? Simply put, music lovers and audiophiles alike have many more choices today when it comes to how they listen to music. As a music system with 150 watts of Class AB power, AiOS combines sources and inputs designed around this new age. AiOS is also fully MQA Certified, but unlike other MQA products to date, AiOS will playback any MQA sample rate up to 16x. This means despite the original sample rate of the MQA file, the MQA decoder will extrapolate the file to either a 705.6 or 768 kHz sampling rate for stunning realism and studio quality sound. For non-MQA files, AiOS can stream or playback native PCM files up to 32 bit 384 kHz (.WAV files up to 768 kHz), plus DSD 64, 128, 256, and 512. Connect AiOS to your home network (Wi-Fi or Ethernet) and stream all of your digital music stored on your networked computer(s) or NAS drive(s) with simple plug N play UPnP, DLNA, and SMB connectivity. Also, available through your home network connection are integrated internet music streaming services, Spotify, TIDAL, vTuner, and others being added. For those that may find a home network connection too intimidating, AiOS allows you to insert a SD Card into the front SD Slot. You can also use a USB flash drive or USB hard drive loaded with digital music files directly to AiOS’ three USB-A inputs, all without a computer or network connection for direct playback! How about Bluetooth? Today, Bluetooth is ubiquitous and AiOS can certainly connect to your smartphone or tablet using the latest Qualcomm aptX© Bluetooth technology. However, AiOS has an extra trick up its sleeve. AiOS can SEND any of its selected sources to Bluetooth enabled headphones or speakers for a completely wireless music system. Place AiOS anywhere to add beauty and elegance to any room or décor and don’t fuss over unsightly wires when paired to a set of Bluetooth enabled speakers.
