I used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system to measure the Peachtree DACiT (see www.ap.com and the January 2008 "As We See It"); for some tests, I also used my vintage Audio Precision System One Dual Domain.
The Peachtree uses the popular Cirrus Logic 8416 S/PDIF receiver chip. The coaxial S/PDIF input successfully locked to datastreams with sample rates ranging from 44.1 to 192kHz. The TosLink input would not lock to datastreams with sample rates greater than 96kHz; this is normal behavior, however, as the…

Many if not most of the world’s most admired albums attained their fame slowly. In the case of Exile on Main Street which was released forty years ago on May 12, 1972, it took years for its ragged, bluesy charms to percolate into the collective psyche and eventually emerge as if not the best, then one of the contenders in the Stones catalog. The debate over an alternative champ has raged for years. Let It Bleed? Some Girls? Sticky Fingers? Beggar’s Banquet? Aftermath? Worthy choices all but when it comes to revelatory experiences, genuine five star records that changed the world, the apex of…
Around the turn of the century, a review of the latest hair-raisingly expensive turntable would often begin with a soothing chant that, yes, the RotorGazmoTron XT-35000 is a tad pricey, but it will be the last piece of analog gear you ever buy—so go ahead, take the plunge. A dozen years later, pressing plants are stamping out LPs 'round the clock, and new high-end turntables are rolling off production lines at a respectable clip. So who knows whether today's Cassandras might be equally premature in bewailing the death of the Compact Disc? Which is to say that I can't in good conscience urge…
The Cipher's way with bass tones was particularly impressive. Thunderous bass has always been one of Krell's specialties, but that's not all I'm talking about here. I'm talking about the details, the melody, even the delicacies of a double bass. On "Mood Indigo," from the Duke's Masterpieces by Ellington (Columbia/Legacy CK 87043, CD), I could hear every pluck of Wendell Marshall's bass, the value of each note, and the shifts in his cadence, even when the full orchestra blares forth. This isn't mere detail for detail's sake; it's crucial to the rhythm—the "mood indigo," if you will, of the…

To measure the Krell Cipher, I used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see www.ap.com and the January 2008 "As We See It"); for some tests, I also used my vintage Audio Precision System One Dual Domain. It wasn't possible to measure the player's performance from its current-mode CAST output, but I did do so from its balanced and unbalanced outputs.
To test the Cipher's performance as an SACD player, I used the "provisional" Sony Test SACD. Although Krell doesn't mention DVD playback on their website in their…
