I looked only at the main left and right outputs. To my surprise, the McCormack offered a lower maximum output level from SACD than it did from CD or DVD-Audio: 1.99V vs 2.35V. This is a difference of almost 1.5dB, which, if not compensated for, will mess up any direct comparisons of SACD and DVD. In addition, the UDP-1's output inverts signal polarity, which will be a confusing factor in comparisons with other players. McCormack doesn't specify the output impedance; I measured 319 ohms across most of the audioband, this rising to 500 ohms at 20Hz. As long as the…
Kalman Rubinson wrote again about the UDP-1 in March 2005 (Vol.28 No.3):
I was stunned when John Atkinson's measurements of the McCormack UDP-1 universal disc player showed that its digital playback of DVD-Audio and SACD discs was not significantly better than its playback of "Red Book" CDs. In fact, JA told me, the UDP-1's digital performance was not substantially different from that of a $150 Pioneer DV-578A-S universal player he'd bought for reference. But I'd been charmed by the UDP-1's sound, which I'd ascribed to the improved power supply for the audio stages and to McCormack's…
"Moi? You want moi to review a French audio product?"
The phone call shocked me—a brickwall SFP (Scull French-Pass) filter usually restricts the flow of such products from moving beyond Jonathan Scull's JMlab-guarded gates. But here was Stereophile's senior editor making me the offer.
"YBA pig about it?" he acknowledged. "Franc-ly, I'd never have assigned it to you, but I've got some bigger fish to French fry this month."
De Gaulle of da guy!

The Cosmos communicated music's inevitable flow with a relaxed precision that was seductive and absolutely addictive. The midrange had a creamy smoothness while never sounding thick, sluggish, or cloying. Nor did the richness of the midrange presentation obscure transient detail. Where my reference Nu-Vista 300 sounds a bit lean and lacking in bloom, the Kora blossomed in a most beguiling way. Live recordings, like Miles Davis' Live at the Blackhawk (Columbia C2S 820 "six-eye"), delivered their full atmospheric and musical potentials. Before the first note was played, I could sense the air…

Stereophile Guide to Home Theater editor Thomas J. Norton used to dread measuring tube amplifiers when he was this magazine's technical editor. I know how feels, the Kora Electronic Concept Cosmos proving a little temperamental on the test bench—three of its 1A output-tube fuses blew at various times during the testing, and one of the 6AS7G tubes suddenly glowed brighter than it should have. After I turned the amplifier off, let it cool down, then turned it on again, this tube had no further problems, however.
The Cosmos had identical sensitivities from…
The plumber's here, and he says we need a new hot-water heater because the one we have now isn't maintaining the correct water temperature, and because it's been in use for nine years. "And the thing is, this is a five-year heater." I responded by repeating his last six words, only louder, and with decorations. And I couldn't help thinking: I've had phono cartridges that lasted longer than that. And none of them have attacked me in the shower when my wife flushed the toilet, either.
It's reasonable to expect five years or more out of a good cartridge, especially if you keep it and your…
