"I've got news for you," I said. "It was sounding like music before your cables were installed. Please—I've been doing this for almost 30 years. Save that line for a kid, okay?"
Sure enough, when we first played music through the Nu-Vista 800, Michaelson gave me that old, familiar look of "Well! There you go!" While I…

I performed a full set of measurements on the Musical Fidelity Nu-Vista 800 (footnote 1) using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). As the amplifier is specified as having a maximum power output of 330Wpc into 8 ohms, I preconditioned it before the measurements by running it at one-third that power into 8 ohms for an hour. Following that period, the top panel was warm, at 99.5°F (37.5°C), and the heatsinks hotter, at 121.9°F (49.9°C).
With the Nu-Vista 800's volume control set to "114.5," its maximum voltage gain at 1kHz…
The event will provide an excellent opportunity to see and hear MartinLogan's new flagship Neolith loudspeakers. Additional featured gear will include AudioQuest's NightHawk headphones, DragonFly USB DAC, JitterBug USB filter, and a range of analog and digital cables.
There will be prizes, as well as…
"Close to two weeks before the show opens, we have already sold more advance tickets than we did at last year's show," very upbeat show promoter Suave Kajko told Stereophile. This should translate…
I have only myself to blame. For years, I have shared with her my every joy that came of finding, at a lawn sale or garage sale or on eBay or at a record store whose proprietors "had no idea what this thing is worth," some rare and valuable treasure. And therein lay another facet of my problem: As often as I would rejoice at the music I was poised to enjoy, or the sheer pleasure of acquiring something rare and well made, I…

By the time I reviewed the Mk.2 version, in the October 1984 issue of Hi-Fi News & Record Review, the A60's price had risen to £199 ($248), the company was now called Arcam, and more than 22,000 A60s had been sold, making it one of the best-selling amplifiers in England. While preparing that review I had visited Arcam's factory, near the…
