Sony CDP-X77ES CD player Is a Bit Bits?
Sony CDP-X77ES CD player
With Sony's latest flagship single-box player ($1700), we find yet another variant on 1-bit D/A technologyHigh Density Linear Converter, or HDLC. At the heart of this Pulse Length Modulation (footnote 1) D/A technique is Sony's CXD-2552 Pulse D/A converter (two per channel in complementary mode in the CDP-X77ES). This complex LSI chip incorporates a third-order noise shaper, the PLM converter, and a digital sync circuit receiving its input from the system clock.

Steve Guttenberg's 116th Dream
I'm at Dan D'Agostino's house listening to his triamped Apogee full-range ribbon speakers. It's 1985. His listening room is immense, easily 30' by 45', and we're rocking out to Led Zeppelin and Bonzo Dog Band records. The sound is light-years better than anything I've hearddynamic as hell, beyond vivid, and the soundstage has infinite depthand Dan's obviously loving that I'm blown away by his system. We get to talking. He has three pairs of Krell KMA-160 monoblocks and Reference KRS preamps for me. Thanks, I say, but how can I get them home? No problemDan has a van.

Reflections of an RMAF First Timer
The 2016 Rocky Mountain Audio Fest
has come and gone, and here I find myself, back in the quiet comfort of Brooklyn.
Back with a glass of red wine in my hand, a table full of hot Indian takeout, and a dreamy Chet Baker serenading me through my modest system: a Technics SL 1200 Mk. II turntable with an Audio Technica AT440MLa cartridge (on a Technics headshell), a Fisher 800-C stereo receiver, and a pair of Rogers LS3/5a monitors sitting atop Skylan Speaker Stands.
What more is there to life?
. . . Or so I had thought . . .
Being There & the Summer of Love
Peter Wolter, owner of a hi-fi shop in the town of Orangeville, Ontarioabout an hour's drive from Torontoin another life worked in marketing for a major pharmaceutical company. This marketing experience undoubtedly informs Wolter's approach to audio retailing . . . he recently presented a vinyl playback evening, celebrating (a little early) the 50th anniversary of the 1967 Summer of Love, and, coincidentally, the renaming of his store. (The pieces of strudel in the picture came from Peter Wolter's family's bakery. And, yes, they were as delicious as they look.)
Our November Issue: What's Old Is New Again
Horn speakers, with their often ridiculously high sensitivity and ear-shocking "jump factor," fascinate many audiophiles. But their sonic flaws can be as big as their musical and technical virtues. The November Stereophile features on its cover and in an extended version of Art Dudley's "Listening" column the Hommage Cinema speaker from German company Auditorium 23, which features remanufactured versions of classic Western Electric compression drivers.
