THE VERDICT
Kaleidescape new compact Terra Movie Server delivers an improved user experience and greater flexibility over the company’s standard Strato system.

Kaleidescape sure has been busy since I reviewed its Strato S 4K Ultra HD Movie Player late last year (October/ November 2020 issue). The company added three new servers to its Terra lineup: the compact 6TB ($5,995), 12TB ($7,995), 18TB ($9,995) options, and a 72TB monster ($23,995) for those who want massive storage without having to string multiple Terra units together. For this review, I was sent the 12TB Terra, along with a Strato C 4K Movie Player (recently reduced in price to $2,995) to test it with. I'll focus first on the 12TB Terra and then give an update on my overall Kaleidescape experience after living with a system for over a year (I purchased my Strato S review unit).

Reference-quality power and D-to-A conversion
Excellent on-board phono section
Onboard Dirac Live room correction

Coarse “app” volume control steps
No USB type-B port for computer connection
Occasionally wonky AirPlay 2 streaming

THE VERDICT
The M33 combines state-of-the- art sound, power, and broad functionality in an elegantly conceived package.

Boy, has NAD come a long way. Back in 1978, the Canadian/ American/Euro multinational's first product was an unassuming but great-sounding little 20-watt integrated amplifier in a plain gray sheetmetal box, with controls that had all the sophisticated feel of a Kenner Easy-Bake Oven.

Analog audio quality
Occasional lockups

THE VERDICT
The SRT4 is a value-priced multi-zone streamer that will fill your house with music for not much money, but also comes with ergonomic and sound quality limitations.

Housewide audio distribution has evolved rapidly over the past few years, with new systems abandoning traditional music sources like CD changers and terrestrial radio tuners to move almost exclusively to streamed content. When it comes to choosing a multizone music streamer for a system, the buying criteria today often boils down to how many streaming services it supports, app ease of use, and cost.

THE VERDICT
NAD's streaming preamp brings vinyl playback and Dirac Live room correction to the mix for a very complete package at an affordable price.

I'm no stranger to the network audio player/preamplifier category, having evaluated two such specimens in 2019: Cary Audio's DMS-550 and Simaudio's Moon 390. These components act as a hub for switching a range of digital and analog sources, along with streaming music from online services and local networked storage. The DMS-550 and Moon 390 impressed me with their versatility and sound quality, but at $5,000-plus, both are priced outside the range of an average listener. Fortunately, other options exist such as the NAD C 658, a $1,649 network audio player/ preamplifier aimed at audiophiles on a budget. How does the C 658 hold up against the pricier models? Let's give it a listen.

THE VERDICT
With its extensive features and flexible sound output options, Cary Audio's DMS-550 network audio player represents digital audio playback done right.

Network audio players are an emerging component category aimed at audiophiles who have made a full leap into music streaming. Many such components can also act as a preamplifier by accommodating externally connected sources such as a CD player or turntable and passing on a line-level signal to an amplifier. Because they are network-connected, streaming high-res audio files from a computer or NAS is also on the features menu, and higher-end models are often Roon Ready and MQA Certified.

Occasionally slow volume-control response via iOS app

THE VERDICT
An excellent solution, for those who can afford it, for a streaming/computer-audio system where sound quality is as important as features or user interface.

Is it an integrated amplifier with onboard wireless and network streaming, or an audio streamer with built-in amplification?

Yes. The Uniti Atom, from British iconoclast Naim Audio, is both of these, as well as a quarterback for the company’s Mu-so wireless- multiroom ecosystem (and a few other things mixed in). Like all Naim products since the brand’s inception in the mid-1970s, the Atom is distinctly different from most competing designs in both appearance and operation; the company’s proximity to the powerful vibrations of Stonehenge doubtless has something to do with this tradition. That said, the Atom is less different from its competition than many a previous design, because this sort of streaming amp is what the classic stereo integrated amp seems to have morphed into, here in the post- physical-media 21st century. But perhaps the rest of the world has simply caught up, or caught sideways, to Naim.
