Tube Power Amp Reviews

Not since Sonus Faber's Amati Homage loudspeakers took up residence in my listening room has a piece of audio gear elicited so many "Oohs," "Aahs," and "Wows" from friends as Hovland Company's dramatic-looking, EL34-driven Sapphire power amplifier—especially when it was switched on and glowing orange and blue. It drew unsolicited attention and admiration even when turned off. Not that, on or off, its unusual looks didn't also have their share of detractors. As with Hovland's chrome-façaded, blue-backlit HP-100 preamplifier, some found the Sapphire too shiny, too gaudy, and generally just too much. Me, I'm thumbs-up on the Sapphire's looks—I found myself staring at it incessantly. But anything that draws such intensity of response, whether love or hate, must be doing something right. B&O shouldn't have a monopoly on striking-looking audio gear.

It's always good to tear into a good steak with Tor Sivertsen, Conrad-Johnson's main marketing man.

"Larry—if I'd told you 10 years ago that McIntosh would be heavily into tubes in the 21st century, what would you have said?"

I wasn't raised a McIntosh lad. My dad used Fisher, Bogen, Leak, and Ampex tubed electronics—and, at one time, even home-built speakers—to keep the house filled with a steady, enriching flow of Mozart. He never owned a Mac component, and, when going upmarket, reached for B&O, alas. So while I knew that many audiophiles hold tubed McIntosh gear—especially the early designs—in very high regard, I was somehow never bitten or smitten. But let's face it—for lo these many years, McIntosh has been for many the name in quality American audio. Take my friend Dan, to whom I've referred several times in the pages of Stereophile. He runs a tubed Conrad-Johnson 9 preamplifier, but wouldn't dream of giving up his 270Wpc solid-state McIntosh MC7270. He's goldurn proud of it!

"More power!!!"

How much power do you really need? What does it do for you, anyway? Even before the single-ended renaissance, the prevailing wisdom was that you really didn't need that much power. When I had a pair of Met 7 speakers, even the "1 watt" indicator LED was hardly ever lit. Ditto for my time with a Threshold Stasis Two—all those cool power-indicator LEDs just sat there dark. Besides, everyone knows that power can be had only at tremendous cost, both monetary and in terms of other performance attributes.
