For several months, my wife and I had been living in a cozy studio apartment in New York's Financial District while our apartment underwent substantial renovations. All the old furniture was sold or donated, and decades of accumulated stuff was subjected to triage (sell, donate, or store). All my audio equipment, parts, and tools suffered the same fate. Downtown, my listening was via pretty decent headphones (B&W Px8, Audeze LCD-XC) connected to a Mytek Brooklyn+ DAC and my PC. Meanwhile, we were very busy shopping to equip the "new" apartment.

An all-in-one streamer-DAC-preamp would not have held much appeal for me if my old system was up and running. This, however, was a different time, and I was offered the Grimm MU2 for review with ideal timing.

One thing that interested me about the StormAudio ISP Evo is that, despite its obvious hi-fi function, it's more like a computer than a typical "prepro." While it does offer a few "legacy" analog inputs, it is for the most part all-digital, input to output, including network connections on both ends. Consequently, it is less likely to leave sonic fingerprints on the music than devices that convert digital to/from analog or modulate their signals with active amplification or attenuation. It is notable that, despite its audio function, the Storm completely lacks traditional audio specifications—distortion, dynamic range, and so on.

Yes, that aspect of the product was appealing, but the real trigger for me was that when I began this review, the StormAudio ISP Evo was the only consumer device to fully incorporate the latest version of Dirac Live Active Room Treatment (ART).

I've been running a 5.1 system for years. Recently, I expanded it to 5.3 with the addition of two more subwoofers. This system is manageable with one of my eight-channel DACs.

Even more recently, I dipped my toe into Dolby Atmos, which made it necessary to lash up at least four more channels. That was a big problem, since neither JRiver nor Roon can support and sync more than one output device at a time, and the multichannel DACs I already owned tap out at eight channels.

I turned to the Arvus H2-4D Renderer, which offers 16 channels of digital output over AES3 and 16 channels of balanced-analog output. This worked, but piping everything through the Arvus meant forswearing DSP, including DiracLive. I really needed a DAC with at least 12 channels.

The Merging+Hapi has been around for years...

When I got these new speakers for review, they were so new that, at the time I unpacked them, no official user manual was included or posted on the manufacturer's website, and the promised matching stands didn't exist. Yet, I have the abiding feeling that I am getting to the party long after it has started. The Mobile Fidelity SourcePoint 8 is the newer, smaller sibling of the SourcePoint 10 reviewed by John Atkinson in Stereophile's February 2023 issue, with a follow-up by Ken Micallef in June.

Over a lifetime of involvement in audio, I have had standmount speakers—bookshelf speakers, as they were called back then—only twice. My very first loudspeaker was a vinyl-wrapped fiberboard bookshelf box with no name. It lasted barely a year and was replaced with a two-way system I built with a 12" RCA woofer in a floorstanding bass-reflex cabinet. My second bookshelf system was a Weathers "Book" speaker lashed up to a University dual-voice-coil woofer. I was determined to try that new thing, stereo.

Since then, I've had only floorstanders, home-made and manufactured, and I never seriously considered owning small speakers again except, perhaps, as part of a surround sound system. With that bias, why am I reviewing the B&W 705 S3?

Planned for KEF's 60th anniversary, much as the LS50 was planned for the company's 50th, the LS60 Wireless is a statement product that encompasses the premise of company founder Raymond Cooke that loudspeaker performance could be improved through the application of new materials and new technologies. Improvements in recent KEF designs include the refinement of the Uni-Q coaxial driver, Metamaterial Absorption Technology (MAT), force-canceling Uni-Core woofers with P-Flex surrounds, cabinets shaped to reduce diffraction, and the configuration and arrangement of drivers to create what KEF calls a Single Apparent Source.

The Topping DM7 DAC ($599.99) is a high-resolution, eight-channel DAC that supports PCM and DSD sources but will not handle any of the common Dolby/DTS codecs. It employs the highly capable and respected ES-9038PRO DAC chip, ESS's flagship. It has just one input, and it's USB. Its eight analog outputs are fully balanced, but they are TRS (tip-ring-sleeve) phone jacks, which are more widely used in pro audio; most audiophiles will require adapters.
