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…
Tuesday, October 27, 6–9pm: Huppin's (8016 North Division, Spokane) will host an evening of music, hi-fi, and technology. Manufacturer representatives from AudioQuest, Klipsch, MartinLogan, and McIntosh will be on hand to share new products, play great music, and answer questions.
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…
In the world of record collecting, those who are obsessed by 45’s, 7” singles, are a special breed. It’s a strain of record collecting that I’ve fortunately not contracted. I have a couple pals though who are deep into singles. After the endless arguments about sound quality, how 45s sound better than LPs—one beer and we’re off—going record shopping with them is an all day affair. After digging through every box in the store, they have to listen to each and every single that looks interesting, looking of course for that special groove, that ultimate jam. They live to seek the little black…
Canada's biggest three-day consumer audio and lots more show, TAVES, is poised to break its former attendance record when it opens in Toronto, Ontario on October 30. Newly reframed as "Canada's Ultimate Consumer Electronics Show," it opens less than a month after Denver's Rocky Mountain Audio Fest, and a mere week before the start of the Westchester County version of the New York Audio Show.
"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…
Please don't tell her I said this, but lately, my wife has been getting twitchy about my records. Twitchy as in: She wants me to sell them. Or at least some of them.
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…
At the same time, let's not become too blasé about our more familiar tubular friends: the 12AX7, the KT88, and the EL34—especially the EL34. That classic pentode tube, introduced in 1954 by Mullard Ltd., has been at the heart of some of my favorite amplifiers, most of which commit the equally counterrevolutionary sin of being push-pull instead of single-ended. How I would hate to wind up in a world in which fondness for push-pull EL34 amplifiers is met with the same scorn as love for Elton John records, some of which are actually pretty good.
Today I'm enjoying a new EL34-based…
I first met electronics engineer John Dawson in 1979, at a British audio show. The company he'd co-founded, A&R Cambridge, had just launched the A60, a slim, elegant-looking, 40Wpc integrated amplifier costing only £99 (then equivalent to $217).
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…
Reflection, the first album from British blues band Steamhammer (24/192 ALAC needle drop from LP, English CBS 63611), is a guilty pleasure of mine, considering the album's excessive use of compression and artificial reverb. In my favorite track, "Even the Clock," the threads in the mix—chiming lead guitar, picked rhythm-guitar riff, offstage flute, spring-reverb splashes on the sound of the clock at the beginning, and the suck-and-blow compression effects on the drums, cymbals, and ostinato bass line—were all laid bare by the Arcam P49, but without disturbing the holistic quality of the…
