Again, when I listened…

The CD32 still added a bit of extra body and warmth, but much less than the CD31. This, too, seemed less a frequency-response variation than a slight difference in the level of focus and clarity. When I listened very carefully, the CD32 was a little more detailed and transparent through the midrange than above or below it. In the Brahms, for example, the violins were right there. They had a stunning amount of inner detail, and their images were sharply bounded in three dimensions. The cellos, in contrast, were gorgeously warm and rich but not quite as detailed.

I looked at the Primare CD32's measured performance using my 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. Unless otherwise mentioned, the measured results refer to the player used with its upsampling turned off and were taken from the balanced outputs. I tested the Primare's behavior only with test signals on CD; the CD32 didn't recognize uncompressed files stored on a flash drive plugged into its rear-panel USB port, only MP3s.

When I began my journey into audiophilia, I was in awe of the Audio Research Corporation's flagship SP preamplifiers. As I sat there in the early 1980s with my modest Apt Holman preamp, all of my friends had ARC SP6Bs. By today's standards, the SP6B was colored, did not portray a realistic soundstage, and lacked sufficient gain to amplify the low-output moving-coil cartridges of the day. But it had an intimacy in the midrange that was intoxicating. (Still considered a classic design by many, the SP6B's price on the used market has remained virtually unchanged for 30 years.) Then, still in…
With really good orchestral recordings, such as Analogue Productions' new reissues of recordings by Fritz Reiner and the Chicago Symphony—Mussorgsky-Ravel's Pictures at an Exhibition (LP, RCA Living Stereo/Analogue Productions LSC-2201) and Rimsky-Korsakov's Scheherazade (LSC-2246)—the CSO was reproduced with forceful dynamics, no compression, and a vibrant, airy facsimile of the recording venue's acoustic. In both of these recordings, all instruments were perfectly delineated across a wide, deep stage. And with Penderecki's Cello Concerto 1, with soloist Siegfried Palm and the composer…

I used my top-of-the-line Audio Precision SYS2722 system (see www.ap.com and the January 2008 "As We See It") to measure the Audio Research SP20. With the SP20's volume control set to "103," the maximum gain for balanced line input and balanced output was basically to specification at 13.9dB. The volume control is implemented with close-tolerance Analog Devices AD5293 chips and the unity-gain setting was between "83" and "84." For single-ended line input/output, the maximum gain was 7.7dB and the unity-gain setting was "73." The gain at the Tape Out jacks was…
Friday morning, May 30, was Day One of T.H.E Show Newport Beach. With the opening bell struck, as it were, by a ribbon-cutting ceremony in the lobby of the Hilton that I miss due to a very slow kitchen at the adjacent Atrium hotel, I dash from hotel to hotel to discover, instead of a frayed red Mylar ribbon or a row of hot, class-A amplifiers, a line of audio hot-rodded classic and contemporary cars.
"The car show folks must be very happy," I think. After several years of finding themselves hidden away in the far reaches of the Hilton courtyard, basically off everyone's beaten path, they'…
