StormAudio ISP Evo IMMERSIVE SOUND PREAMP/PROCESSOR
Stereophile|March 2024
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."

StormAudio ISP Evo IMMERSIVE SOUND PREAMP/PROCESSOR

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). An earlier, more primitive version of ART, called DLBC Full Bass Optimisation, was tantalizing² but ran only on Windows or Mac computers and seemed never to get out of beta status. My expectation for the ISP Evo is that the installation and calibration procedures of this integrated version, which is now fully commercial and public, will be more coherent and smoother and that the results will be even better than before.

That's quite an attractive package, but it comes at the cost of easy integration. The ISP Evo cannot just be plunked down into any audio or home-theater system because its primary output is via network. Since it is "AoIP (AES67/Ravenna) Dante Compatible," it can communicate directly to network-enabled loudspeakers, DACs, amplifiers, and other devices-but not to those that don't speak one of those network dialects. In my setup, I needed to connect it to my PC Server by running the appropriate drivers in order to play files from my library or to stream music from the internet; Merging's MAD ASIO driver package installed on my PC server enabled bidirectional flow of multichannel audio between it and the ISP Evo.

Technics SC-CX700 ACTIVE LOUDSPEAKER

The usual Specifications box (below) is a nuts-and-bolts listing of the electrical and physical properties of the Technics SC-CX700 loudspeaker, who made it and where, and a widely varying amount of information about their electrical and acoustical performance. The information comes from the included literature, available downloads, and whatever I could find on the manufacturer's website.

The Loricraft PRC6i record cleaning machine and the WallySkater v2.1 Pro

In my last Spin Doctor column, I gave an overview of my experiences cleaning records over the last 50-plus years and the advances in record cleaning technology over that time. My review of the HumminGuru NOVA ultrasonic record cleaner focused on that increasingly popular approach to record cleaning, using ultrasonic cavitation instead of scrubbing the record with a brush. But if there’s one thing I’ve learned in that half-century of playing around with audio gear, it’s that it can be a mistake to embrace a new technology just because of its newness, dismissing what came before as obsolete. The vinyl record itself is a good example of a technology discarded as obsolete, then embraced again by new (and old) generations. You can add vacuum-tube amplifiers, analog tape, and much else in our hobby to that list.

The Voxativ Hagen2 Monitor loudspeaker

I think I just found the perfect Herb speaker. It uses a hand-crafted 5\" wide-range driver with a cone made from Japanese calligraphy paper. It rolls off around 50Hz at the bottom and 30kHz at the top. It has no crossover. Its cabinet is made of MDF that responds loudly when I tap it with my fingernails. Inside is what its designer calls a “short horn,” which appears to harmlessly disperse back-cone energy while adding energy below the driver’s cutoff frequency. Mainly, though, it’s a perfect Herb speaker because it is naturally phase coherent. And sparkplug fast. And completely unmuffled.
