Editor's Note: One-bit DAC chips in the 21st century, where the analog output signal is reconstructed from a very high-rate stream of pulses, are ubiquitous. But a quarter-century ago, those chips were only just beginning to stream from the chip foundries. In this feature, we aggregate Stereophile's 1989 coverage of the then-new technology, starting with Peter van Willenswaard on the basics.—John Atkinson.

1989 may well become the year of the D/A converter (DAC). CD-player manufacturers have, almost without exception, launched research projects focusing on this problem area of digital audio; many of these projects are already a year old. This is, however, by no means the only imperfection keeping us away from the high-quality sound we have come to suspect is possible with digital audio media, and maybe not even the most important.

Peachtree Packs 'Em In

AXPONA 2013

John Atkinson | Mar 15, 2013 | 1 comments

Peachtree's room was typical at AXPONA, packed with an enthusiastic crowd of listeners enjoying the music all weekend. The Peachtree Nova125 that Sam Tellig reviewed in January ($1499) was being demmed with the MartinLogan Montis speakers that Robert Deutsch reviewed in September 2012 ($9995/pair). The speakers were certainly not let down by the inexpensive amplifier—"The Nova125 will handle any source, any speakers," proclaimed Peachtree's Jonathan Derda (below)—who played me Rickie Lee Jones on LP on a Pro-Ject turntable with Phono Box dual-mono phono preamp, the sax-and-bass duet on Sting's "Standing on the Moon, from a Turtle Records hi-rez file, and even a luminous-sounding MP3 streamed from Spotify.

Peachtree's Grand Pre

RMAF 2011

John Atkinson | Oct 20, 2011 | 0 comments

It's the perfect name for a preamp, I thought. Grand Pre, if not Grand Prix, has a certain ring to it. The first upmarket product from the company that has made a name for itself with its high-performance iDecco, iNova, and iDac, the Grand Pre will be priced at $3000. It combines the high-resolution ESS 9018 DAC chip with a buffer stage based on 12AX7 tubes, and offers both analog and digital inputs, including a 24/192k-capable USB input. Peachtree's David Solomon, shown in my photo,was demming the Grand Pre with a Simaudio Moon amplifier driving B&W 802 Diamond speakers, using Pure Music on his laptop to send it USB data.

Peachtree’s $2k System

T.H.E. Show Newport 2012

In the fourth of the Sunny’s Audio rooms—see Jason Serinus’s stories earlier in this report—was a jewel of an affordable system, being operated here by Peachtree’s David Solomon. Peachtree’s new decco65 D/A integrated amplifier ($899), which uses a 24-bit ESS Sabre DAC and offers 65Wpc into 8 ohms, drove Dynaudio DM2/6 bookshelf speakers, the system being completed with an Apple TV and cables to give a total cost of $2000. All you need add to get music is a PC.

Peak Consults Chords

CES 2011

John Atkinson | Jan 12, 2011 | 0 comments

Bluebird Music's Jay Rein wanted to hear the Bluetooth-driven Chordette Gem-based system at the front of the room, with Spendor A6 speakers, but my attention was drawn to the familiar-looking speakers at the other end of the room, Peak Consult El Diablo Vs ($89,000/pair), which Michael Fremer reviewed in May 2007. Jay explained that he is ow the North American distributor for these Danish speakers.

The speakers were being driven by Chord SPM1400 monoblocks ($$32,900/pair) and a Chord CPS5000 preamp, with van den Hul's new Mountain interconnects and Nova speaker cables. Jay put the Reference Recordings CD of Scheherazade (RR-89CD) with Jose Serebrier conducting the London Philharmonic Orchestra into the Chord Red Reference Mk,II CD player ($25,900) and for an all-too-brief interlude, I was transported from the fake glitz of Las Vegas into the more real sonic world of the Arabian Nights.

Penaudio–dCS–Musical Fidelity

CES 2012

John Atkinson | Jan 18, 2012 | 1 comments

If the Lamm room in the Venetian with the Wilsons was one of the first I visited at CES, the last room I visited was Tempo Marketing's in the Mirage Penthouse. I reported last October that Tempo had taken over US distribution of this Scandinavian brand. As well as the stand-mounted Cenya ($4000/pair), which I had heard at the 2011 RMAF, Tempo was demming the floorstanding, two-and-a-half-way Sara S ($7995/pair), shown in my photo. The Sara S combines two magnesium-cone SEAS mid-woofers with a SEAS tweeter in an enclosure that comprises a unique construction combining MDF and plywood.

As at previous Montreal Shows, parts and drive-unit distributor Solen Électronique had a room to show off their gear to DIY enthusiasts. But even anachrophile Art Dudley was puzzled by the center of this whizzer-cone fitted drive-unit sitting in his hand.

Perfect Sound Forever?

As We See It

John Atkinson | May 01, 1995 | 1 comments

When some unknown copywriter coined that immortal phrase to promote the worldwide launch of Compact Disc in late 1982, little did he or she foresee how quickly it would become a term of ridicule. Yes, early CDs and players offered low background noise, a flat spectral balance, and freedom from wow and flutter. But all too often, the music encoded in the "perfect-sounding" pits seemed to have taken a vacation, leading the renowned recording engineer John Eargle to offer, in the medium's defense, that if you were to hear just one CD that sounded good, digital technology would be proved to be okay.

Perfect8's Point Mk.II

CES 2012

John Atkinson | Jan 20, 2012 | 0 comments

At the 2011 CES, Swedish company Perfect8 concentrated on their Force flagship speaker. For the 2012 Show, they brought their Point Mk.II ($115,000/pair with subwoofer modules), which, like its big sister, uses an enclosure fabricated from glass—or rather, from what Perfect8 calls "Super Silent Glass," joined without solvent-based adhesives. The upper-frequency module is a dipole, allowed to roll off naturally to integrate with the subwoofer module below it, which uses two 10" drive-units mounted on its sides to cancel mechanical reaction forces. The woofer's low-pass filter is set at 86Hz and realized in DSP; the module includes a class-D amplifier housed in the triangular section at the rear. Despite my reservations about glass as an enclosure material, both Diana Krall and Rimsky-Korsakov sounded uncolored and natural.

I am saddened to report that Peter James Walker, the founder of quintessential English audio company Quad, passed away on December 10, after a long illness. He was 87. Peter Walker had been married twice; both his wives had died before him. He is survived by a daughter, Victoria, and a son, Ross, the latter having played a major role in managing Quad through the 1970s and '80s.
