Dynaco ST-70 Series 3 Tube Power Amplifier

Dynaco ST-70 Series 3 Tube Power Amplifier

Back to the future. When Radial Engineering announced its plans to market a modern version of the Dynaco Stereo 70, the news struck me as a valiant time shift, aimed squarely at resurrecting the soul of one of the most influential amps of all time, and the component that enshrined Dynaco in audio’s Hall of Fame. Over a span of nearly 20 years in the 1960s and 70s, more than 400,000 ST-70s were sold both in kit and assembled forms, total sales by some estimates approaching half a million by 1977.… Read the full article

Audio by Van Alstine Transcendence 10 RB Preamplifier and Vision SET 120 Stereo Power Amplifier

What constitutes the “entry level” isn’t always obvious. Because we live in an Internet-infected world where fluidity, shape-shifting, social relativity, distributed systems, etc. are commonly accepted models of reality, definitions are rarely clear-cut or easy. That’s what people say, anyway. Fortunately, this is my column, and I get to make the rules. I admit, though, the entry level is probably one of the most nebulous terms out there. What’s affordable for me isn’t always affordable for someone else, and so on.… Read the full article

Air Tight ATM-300R power amplifier

By | January 24th, 2019|Categories: Stereophile|

To audio designers in Japan and elsewhere, the single-ended, 300B-tubed amplifier is like a haiku: an art form defined by both its prescribed limitations and the potential such restraint offers for artistic expression. Here, the only hard-and-fast rule is a simple one: output devices are limited to one 300B directly heated triode tube per channel. From there, it’s a blank slate: Do you want AC or DC on the output-tube heaters? Tube or solid-state rectification? Low or high gain? Fixed or cathode bias?… Read the full article

First Watt SIT-3 power amplifier

By | January 22nd, 2019|Categories: Stereophile|

I am obliged to begin this review of First Watt’s new stereo power amplifier, the SIT-3, with an explanation of how I believe a power amplifier should be reviewed. Why? Because the 18Wpc SIT-3 is a unique and historically important design that can’t be wired up to just any loudspeaker and then critiqued on the basis of its bass power, treble brightness, or midrange acuity.

Years ago, a reviewer friend said, “Herb, I don’t review loudspeakers.”

I was shocked. “Why?”

“Because my speakers are too heavy to move.”

“So then?… Read the full article

Bryston 28B³ Monoblock Power Amplifiers

Screen Shot 2019-01-14 at 10.53.20 AM.png

According to its website, Bryston has been in business for 35 years, has 150 dealers in North America and is in 60 countries worldwide. That is very impressive for an audio company. Bryston headquarters is located in Peterborough, Ontario, Canada, which is approximately a 2 hour drive from my hometown, Toronto.

Even though I have known about Bryston for decades, I have not reviewed any of their products nor have I heard any of their products for an extended period of time.… Read the full article

Cary Audio CAD-805RS monoblock power amplifier

By | December 20th, 2018|Categories: Stereophile|

There’s no place for fashion in epidemiology, aeronautical engineering, or the mining and storage of uranium. Fortunately, domestic audio is less serious, its goals more scattered and ambiguous, than those and a thousand other pursuits.

And so, throughout the 20th century, any number of trends in domestic audio popped up their heads, some remembered as fads, others as legitimate approaches to playback. Among the latter are amplifiers whose output sections operate in single-ended mode, in which the entire signal waveform is amplified by a single device (footnote 1)—usually a tube, most often a triode—rather than being split into positive and negative halves and sent to complementary pairs of output devices.… Read the full article

Audio Mirror SET Monoblock Power Amplifier

Audio Mirror SET Monoblock Power Amplifier

To confess, I developed a soft spot for the Russian 6C33C-B power triode after I first heard it perform in a Balanced Audio Technology (BAT) amplifier many years ago. Even under CES show conditions, while driving Avantgarde Acoustics loudspeakers, the BAT’s warm and spacious acoustic etched itself indelibly in my auditory memory bank. This tube has been championed by Russian-born designers such as BAT’s Victor Khomenko and Lamm Audio’s Vladimir Lamm, but it was totally unknown in the West prior to the defection in 1976 of Soviet pilot Viktor Belenko.… Read the full article

2019 High-End Audio Buyer’s Guide: Power Amplifiers $5,000 – $20,000

2019 High-End Audio Buyer’s Guide: Power Amplifiers $5,000 - $20,000

McIntosh Labs MC275 VI $5500 The sixth version of this most classic of all McIntosh amplifiers is by far the best, boasting greater tonal neutrality yet without losing the beautifully solid, rounded, dimensional, and natural musicality of its tube origins. Thanks to improvements in the transformers, distortion and noise are far lower than ever, bandwidth higher, dynamic range wider, transparency greater, and transient response better than ever. At 75Wpc (though 90 is typical), the 275 has virtually all the power PS needs, but for those who want more, it’s strappable to 150W.… Read the full article

Boulder 1110 Preamplifier and 1160 Power Amplifier

Boulder 1110 Preamplifier and 1160 Power Amplifier

There are a number of top high-end electronics manufacturers that you can trust to put out an excellent new preamplifier and amplifier even before you audition them. If you have listened to such manufacturers’ products over time, you also find that real improvements in the new series are always there but generally subtle. You also detect that the company’s equipment tends to be consistently “voiced” in ways that prioritize a given mix of sound qualities. The best manufacturers keep this voicing as limited as possible, but it is always there.… Read the full article

Audio Research VT80SE Power Amplifier

Audio Research VT80SE Power Amplifier

Audio Research Corporation, the company that almost single-handedly created high-end audio electronics, not to mention preserved the vacuum tube as an amplification device, recently revised its basic line. As it has become the foundation for ARC’s more expensive gear, it is appropriately named the Foundation Series and comprises the LS28 linestage (a 2017 Golden Ear Award recipient), DAC9 DAC, PH9 phono preamp, and VT80SE power amplifier. Each of the first three pieces of Foundation Series equipment is priced at $7500; the much larger and heavier VT80SE is $8900.… Read the full article
