Back in the summer of 2009, USB-connected D/A processors that could operate at sample rates greater than 48kHz were rare. Ayre Acoustics had just released its groundbreaking QB-9, one of the first DACs to use Gordon Rankin's Streamlength code for Texas Instruments' TAS1020 USB 1.1 receiver chip. Streamlength allowed the chip to operate in the sonically beneficial asynchronous mode, where the PC sourcing the audio data is slaved to the DAC. But high-performance, USB-connected DACs like the Ayre were also relatively expensive back then, so in the January 2010 issue of Stereophile I reviewed a pair of soundcards from major computer manufacturer ASUS , the Xonar Essence ST and STX, which, at $200, offered a much more cost-effective means of playing hi-rez files on a PC.

Most folks don't even know they exist, but the Channel Islands are a chain of eight moderately sized mountains poking through the Pacific Ocean along the coast of southern California, between Santa Barbara and San Diego. The most famous of these is Catalina Island and its city, Avalon, which sit opposite San Clemente. The other Channel Islands are relatively wild and have been preserved mostly uninhabited.

Over half a century after the creation of the prized Everest Records catalog, most of whose 78 classical titles were recorded between 1958 and 1961 on 35mm magnetic tape in three-channel stereo, 61 titles have now been remastered and released in multiple formats. In addition to physical CD and downloadable Mastered for iTunes versions, a still-expanding, luscious hi-res treasure trove of Everest titles may be downloaded from HDTracks's Everest Records pages. All HDTracks titles, remastered from the master tapes in 24/192, are available in both 24/192 and 24/96 versions.

As songwriters go, Guy Clark has been touched by the muse more than most. Unfortunately, in recent years he's also been visited by illness and heartache. In June 2012, his wife of 40 years, Susanna Clark, who was both a songwriter ("Easy from Now On") and an artist (the cover of Willie Nelson's Stardust), died in Nashville. In the past several years Clark, 72, has battled lymphoma, had his knees replaced, and undergone an arterial replacement in one leg. He was being treated for skin cancer when I visited his home, south of Nashville, in October 2013.
