It's been a while since I auditioned a Meridian CD player in my system. I had enthusiastically reviewed the English company's groundbreaking Pro-MCD player in early 1986, and over the years had kept up with the progress they were making in digital playback, either through my own reviews or by performing the measurements to accompany reviews by other Stereophile writers. The 508-24 player, reviewed by Wes Phillips in May 1998, was one of the finest digital products of the 1990s, I thought. But when Meridian began promoting surround sound and DVD-Audio at the turn of the century, their goals…
The apodizing filter used in the 808.2 and 808i.2 was optimized using listening tests. It is realized using a DSP chip operating at 150MIPs with 48-bit precision that also performs the upsampling. It appears that the CD data are first upsampled to 88.2kHz, then processed by the apodizing filter which has a null at 22.05kHz. This is the datastream that is fed to the Meridian's SpeakerLink digital output. The DSP chip then further upsamples the data to 176.4kHz to feed the player's DAC chips.

For this review, I focused on the Meridian 808i.2's performance as a standalone CD…
For my first comparison I used Robert Silverman's performance of Liszt's Liebestraum, from Editor's Choice (CD, Stereophile STPH015-2). The result wasn't what I was expecting from my prior auditioning of this track with the CD played in the Meridian, in that the piano now sounded a touch more bright and not as palpable. The Ayre was clearly preferable. I checked the setting of the dCS. Ah...I'd forgotten to change the 972's output frequency from 96kHz to 44.1kHz, meaning that the dCS was upsampling the CD data before sending it to the Meridian, an additional variable that worked against the…

Sidebar 3: Measurements
I examined the measured behavior of the Meridian 808i.2 Signature Reference using the Audio Precision SYS2722 system (see www.ap.com and "As We See It" in the January 2008 issue), as well as, for some tests, our Audio Precision System One and the Miller Audio Research Jitter Analyzer. For this review, I looked only at the Meridian's performance as a CD player/digital processor. Its measurements as a preamplifier will be included in the Follow-Up discussed in the main body of the review.
With the Meridian set to operate as a player with a fixed output, its…
After Fred Kaplan reviewed Boulder Amplifiers' 810 line preamplifier and 860 power amplifier for the December 2007 Stereophile, John Atkinson requested that I listen to the 860 in my own system for a while. Never having reviewed any Boulder kit, I was curious.
Suffice it to say that I was so impressed by that brief interlude that I wanted to know more about Boulder. I went to the company's factory in Boulder, Colorado, and watched them mill metalwork, stuff circuit boards, and assemble components—all in-house. The impressively clean facility clearly represented millions in…
I then listened to a hi-rez DVD of male choral group Cantus's While You Are Alive (available on CD, Cantus CTS-1208) given me by John Atkinson, who engineered the recording. Oh, lordy—what I said about the acoustic of Merton College Chapel? That was a photocopy of a photograph compared to the sound of Goshen College's Sauder Hall captured by JA. Eric Whiteacre's Lux Arumque simply hummed into being, quietly building an immense sonic world—one light enough to float but massive enough to withstand, well, eternity. Any amplifier capable of transmitting that much emotion is an amp I'm willing to…
