Many loudspeaker designers are minimalists at heart. They embrace a design aesthetic that says that simpler is better. Based on the evidence of the company's R 8 Arreté, Ole Klifoth, of Danish loudspeaker maker Audiovector, is not one of those designers.

On its website, in the Specifications section for its "R"-model loudspeakers (footnote 1), Audiovector offers a long checklist of technologies, many of them optional, some of them, called "Concepts," assigned snappy names and acronyms: IUC for Individual Upgrade Concept; LCC for Low Compression Concept; SEC for Soundstage Enhancement Concept; NES for No Energy Storage; FGC for Freedom Grounding Concept; and NCS for Natural Crystal Structure.

In early May, some of in the music press got an advance look at what was coming soon from Apple Music. Apple announced that, following the example of Tidal, Qobuz, and Amazon Music HD, the company would no longer deal in AAC, their improved (but still lossy) MP3 equivalent.

Henceforth, all Apple stereo downloads and streams would be at at least CD resolution; many tracks would be offered in higher resolutions, up to 24/192. Apple estimated that by the end of 2021, 75 million songs would be available at resolutions of 16/44.1 or better.

EISA, or the Expert Imaging and Sound Association, is an organisation representing 60 of the most respected special interest publications and websites from 29 countries that cover Hi-Fi, Home Theatre Video, Home Theatre Audio, Photography, Mobile Devices, and In-Car Electronics. Every year EISA's Expert Group members, including editors from this publication, test a very wide range of new products from their field of expertise before comparing results and voting to decide the cream of every product category.

The Swedish Rauna company, which has been in existence for about five years—their little Mk.II Tyr two-way impressed J. Gordon Holt a couple of years back in Vol.9 No.2—appears to be dedicated to the use of concrete as an enclosure material. One of the problems with conventional wooden cabinets is that the walls flex and vibrate, adding a spurious and often time-delayed output at some frequencies. It has even been reported that in extreme cases, the contribution of the cabinet to the overall sound at some frequencies approaches that from the drive-units. In theory, concrete should give a rigid construction with any panel resonant frequencies moved up above the critical midrange.

Imagine an electronic magic wand you could wave at your listening room's acoustical problems to make them disappear. The Cambridge Signal Technologies SigTech TF 1120 may be just such an alchemical device. Its efficacy depends on the nature of the acoustical warts in your listening environment. Operating solely within the digital domain, the SigTech device can perform both drastic and subtle frequency-response and time-domain corrections that are beyond the scope of analog-based units. While the TF 1120 is expensive, in some situations it may still be the most cost-effective way of coping with acoustical gremlins. Is it the solution to your problems? Perhaps.
