Reviewers' ChoiceIntegrated amplifiers are the multitaskers of hi-fi, earning their keep by meeting multiple requirements at once. Since they usually need to be priced affordably, integrateds tend to be conservatively designed. That said, many recent models accommodate contemporary listening habits through features like Bluetooth streaming and a USB DAC input. Others, like Hegel Music Systems’ Röst, which I recently reviewed on SoundStage! Simplifi, go further by incorporating a wired LAN connection, IP control, and AirPlay streaming.

Lumin, a brand owned by Pixel Magic Systems Ltd., in Hong Kong, is known for its line of network music players and transports. The M1, their latest product, is a slightly different beast: an elegant, all-in-one component that combines the functionality of a UPnP streamer with a class-D amplifier in a slim housing and selling for $1995 USD. To get up and running, you just connect the M1 to USB storage, or to your home network via Ethernet, download Lumin’s iOS/Android control app, and off you go. It couldn’t be simpler.

Arcam is no stranger to the idea of integrated playback systems, having launched the first Solo Music in 2005. In this second generation of the model ($2000 USD), they update the concept for the streaming era by adding wired and Wi-Fi network connectivity, along with aptX Bluetooth. Like the original, the new Solo Music features a built-in disc player, and DAB/DAB+ and FM tuners. (Terrestrial radio broadcasting -- it’s still a thing!) And if you’re wondering if this is a system aimed at both audiophiles and audio newbies, playback support encompasses CD and SACDs, audiophiles being the only people on earth to own SACDs.

Among American audio brands, it would be difficult to beat McIntosh Laboratory for sheer name -- and image -- recognition: The blue-and-green glowing McIntosh faceplate, with its meters and chunky knobs, is perhaps the most familiar icon of American hi-fi. Though mostly associated with tubed power amplifiers and preamplifiers, in recent years McIntosh has branched out, introducing everything from headphones and media streamers to wireless loudspeakers. Though it continues to manufacture the older product categories it’s best known for, the McIntosh of today is not your dad’s McIntosh.

As a listener, I’m new to Hegel the audio equipment maker. As a reader, I’m familiar with Hegel the German philosopher, mostly due to his influence on the thinking of Karl Marx. Georg Wilhelm Friedrich Hegel (1770-1831) is associated with the Hegelian Dialectic, in which things and ideas evolve in a continual process of change that finds synthesis in an ideal reality. Marx, among other things, is known for turning Hegel on his head by shifting the Hegelian Dialectic from the ideal world back to the material one.
