LATEST ADDITIONS

Marc Sheforgen (left) and Chad Kassem (right) of Acoustic Sounds' Super HiRez DSD download site spilled the beans that in a few weeks, the world's first live-to-DSD hi-rez recordings of "a handful of" blues artists will become available as both stereo and multi-channel downloads. Recorded in the company's Blue Heaven recording studio/concert venue, a converted church in Salina, KS, these may be the first unedited live DSD recordings ever issued.

Hi-rez pioneer/evangelist/recording engineer Mark Waldrep of AIX Records held forth in the Hi-Res Audio Showroom in the Venetian Hotel, near booths from Super HiRez and HDTracks. AIX Records' 2015 sampler, containing three different mixes of 70 tracks drawn from its rich catalog, is due sometime in February.

Critical Mass has just released its new entry-level Sotto Voce equipment rack ($4500 for four tiers). Far more affordable than the company's other racks, it is made of Sapele, a wood that I understand is in the Mahogany family. The rack is upgradeable to include Critical Mass's filter systems that enhance component performance. The upgrade path starts at $225, and can include filter systems that cost up to $2895.

Grant Samuelson of Shunyata Research introduced me to the company's new Sigma series of power cords. Designed to intercept noise at a component's power supply, the Sigmas are available in different models specifically intended for digital, analog, and high-current equipment. Each model has a different ETRON™ filter set that measurably reduces noise for the class of equipment for which it is designed.

It's not every show that a cable company invites a publication's staff to breakfast to preview a power conditioner whose faceplate isn't even ready for viewing. But after a short but most impressive listen to the patent pending circuitry in AudioQuest's forthcoming Niagara 7000 Low-Z Power–AC Grounded Noise-Dissipation System ($TBD), I'm convinced that something special is coming our way.

Synergistic Research has just introduced four levels of its new, hand-fabricated Atmosphere interconnects ($695–$2500 for a 1m/pair, depending upon level) and Atmosphere speaker cables (approx. twice the price). Non-active, which means that they don't need to be connected to an external power supply, albeit actively grounded, the cables come complete with blue and red tuning bullets specifically designed for this new "passive" cable line.

The main joy of returning to audio and writing for Stereophile is the pure fanboy excitement of meeting the folk-heroes of high-end and getting to talk them. In one great-sounding room I got to meet three at once: Wendell Diller of Magnepan (one of the nicest humans in the audio schema) as well as Bill Conrad and Lew Johnson of Conrad-Johnson.
