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

According to Cary Audio designer Dennis Had in this amplifier's documentation, "Countless hours were spent designing and voicing the CAD-280SA V12 stereo amplifier...It delivers high performance in a combination of class-A single-ended triode and true balanced push-pull technology."

"I'm a fan of tubes—I don't like designing with them, but I do like listening to them."—Paul McGowan, Stereophile interview, May 2000

"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?"

The VTM200 is the first Audio Research power amplifier I've reviewed. It took me 13 years, and ultimately I'm glad I'd put that much mileage on my reviewing odometer before tackling what turned out to be a most difficult assignment.

At the last few audio shows, whenever I heard a pair of the big Cary CAD-1610-SEs, I fair licked my chops. The two-tiered monoblock looked positively stunning in black and polished aluminum, exotic tubes bristling from the top "floor" of its two-story edifice. The Cary always induced pelvic tilt in me—you know, when your lizard brain takes over and tube lust is in the air.

The last Lamm product I had my hands on was a pair of M1.1 monoblocks (see Vol.18 No.4, Vol.22 No.7). I liked those hybrid tube/solid-state amps quite a lot.

The internal battle between the head and the heart, between the analytical and romantic sides of our nature, is a difficult one. I'm an engineer, so it seems as if my cold, calculating side should have the upper hand. This is true in a lot of cases; most of my actions and decisions are based on straightforward, logical analyses. However, things like a house full of castaway dogs, or a garage full of quixotic British cars and Italian motorcycles, suggest that my heart holds sway reasonably—perhaps distressingly—often.

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!

Based in the Czech Republic, KR Enterprise is headed by an occasionally gruff Dr. Riccardo Kron and his American-born wife, Eunice, who operate the company out of a partially abandoned factory that was once part of the state-owned Tesla High Vacuum Technology facility in Prague. The Swiss-funded company is unique in that it manufactures both amplifiers and the tubes that power them. KR's tubes have found favor with other amplifier makers as well—especially the 300BXS, electrically identical to a standard 300B but rated at 25W in class-A.

Victor Tiscareno and Byron Collett of AudioPrism are known in audiophile circles for their complete line of power-conditioning products. (See Barry Willis' omnibus review in the December 1998 Stereophile.) Their intimate knowledge of the ever-capricious electrical supply has resulted in a series of front-end components bearing the company's logo. The flagship Mana Reference monoblocks, under consideration here, represent AudioPrism's collected wisdom and engineering savvy taken to its logical extreme.

Many tube aficionados hold that amplifiers built with the venerable 300B tube hold the aces when it comes to sonic purity and beauty of harmonic line. Cary Audio Design's Dennis Had succeeded in producing what many believe is the definitive moderately sized single-ended triode (SET) amplifier: the CAD 300SE. This monoblock, powered by classic 300B Western Electric or derivative tubes, could provide 8–10Wpc, requiring the adoption of relatively moderate volume settings and/or sensitive, easy-to-drive loudspeakers. Cary also produced a lower-priced "integrated" stereo chassis, the CAD 300SEI.

Nagra's VPA amplification system consists of two slim, handsome monoblock amplifiers intended for vertical placement. They look good adjacent to the speakers. However, two 845 tubes put out a lot of heat, so the amplifier should be at least a foot away from your speakers...unless you're looking for a nice crackle finish.
