To measure the Onkyo DX-7555, I used the magazine's older Audio Precision System One and a brand-new Audio Precision System SYS2722 kindly loaned by AP (see "As We See It" and Audio Precision's website), as well as the Miller Audio Research Jitter Analyzer.
The DX-7555 offered excellent error correction, producing no audible glitches in its output until the Pierre Verany Test CD's track 32, the data spiral of which includes 1mm gaps. The Onkyo's maximum output level at 1kHz was 2.06V, close to the CD standard's 2V, and it preserved absolute polarity; ie,…
Wes Phillips wrote about the Onkyo DX-7555 in February 2008 (Vol.31 No.2):
"Still got that Oppo DV970HD universal player you reviewed last May?" asked John Atkinson.
"Yeah," I said, grudgingly, afraid he might want to borrow it.
"Good. I'd like you to listen to the $599 Onkyo DX-7555 CD player, which Robert Deutsch just reviewed for the January issue. He compares it to the Ayre CX-7e, which costs a lot more, and to an older Marantz universal player. I think the Oppo would make a helpful real-world comparison."

It's easy to be impressed by Simaudio's Moon Evolution Andromeda Reference CD player. Everything about it oozes quality and luxury, from its imposing two-chassis configuration to the multi-component disc clamp of machined aluminum. Even surrounded by my double-decker VTL amps, VPI HR-X turntable, and Ferrari Fly-yellow Wilson Audio Sophia 2 speakers, the Andromeda was usually the first thing guests asked about: "How much does that cost?" The answer is $12,500. The Andromeda should look impressive.
Skin-deep or through and through?
The Andromeda Reference, part of the Moon…
A good way to get more specific about the Andromeda's performance is to start by recalling my experience with the Andromeda's predecessor, Simaudio's Moon Eclipse, which was my reference CD player for several years. (See my review in the April 2001 Stereophile, and the Follow-Up in the April 2003 issue.) The Eclipse was one of the best-sounding decks available at the time, and significantly less colored than its contemporaries, but it did have a slight but distinct, and consistently audible, sonic signature. Its strengths were superb reproduction of spatial cues and ambient detail, precise…

Sidebar 3: Measurements
I measured the Simaudio Moon Evolution Andromeda Reference's performance using both our Audio Precision System One and an Audio Precision System SYS2722, the latter on loan from AP (see "As We See It" and Audio Precision's website).
Like Simaudio's single-box SuperNova, reviewed by Wes Phillips in January 2007 (see my measurements), the Andromeda had superb error correction, suffering no glitches in its output with the Pierre Verany test CD until the gaps in the data spiral were more than 2mm in length.
From its unbalanced RCA jacks, the Andromeda'…
Whenever my family and I travel together, I catch a glimpse of how the human mind works. Immediately after checking into our hotel, my wife goes to work distributing the contents of our suitcases among the room's various cabinets, closets, and drawers. Then, the next morning, I discover the location of my underpants heuristically: seeking without knowing, in the hope that some newly learned pattern will be imprinted on my brain. Thus do I earn the luxury of complacence: Every morning thereafter, my things are right where I know they should be.
That procedure is useful not only…
The sound was richly, realistically detailed, without the slightest suggestion of added brightness. The latter quality may seem obvious to the point of being silly, given the 755-C's treble limitations, yet neither did it sound as dull as I might have expected. So far, the Altec has been responsible for at least two reviewing clichés, howsoever pleasant and true: first, that of discovering some worthwhile musical detail that had previously escaped my attention, in this instance the arpeggio that guitarist Tony Rice plays behind the fiddle in the opening bars of his song "Manzanita"; and…
