While walking home from the office the other day I passed a gleaming, perfectly detailed Harley-Davidson, lightly customized, as many are these days. I didn't stop and drool, but I couldn't unsnap my eyes from it. As I drew parallel to that hawg, a Ricky Martin look-alike threw his leg over the saddle and thumbed the starter. No, you don't have to be a tattooed, beer-gutted redneck anymore to rear up and slam down on a kick-starter of one of those beasts. These days, it's all done with the push of a button. Dude.

The word on Bel Canto's upsampling DAC was already out when I visited their room at the 2000 Consumer Electronics Show looking to get one of the first samples. But despite my protestations, all Bel Canto's Mike McCormick wanted to talk about was their company's new digital amp, the eVo 200.2. Sure, there's a future out there in which all sources will be digital and D/A conversion will occur in the speaker (or later?). But today, I see no practical advantage in a digital amplifier with only an analog input. It may be more efficient and it may be new technology, but the amplifier has got to stand on the same footing as any analog design and justify its existence by the way it sounds. The eVo did make a good case for itself at the demo, so I signed up to get one for review.

Keith Herron plopped himself down in my listening chair and smiled, clearly pleased with the sound of my system now that his M150 monoblock power amplifiers had been substituted for my Musical Fidelity Nu-Vista 300. He began to tell me why.

I've been attending the annual Consumer Electronics Show for years, and usually come away with the impression that there are too many "me-too" products. I see a numbing similarity of approach of manufacturers within a chosen discipline: solid-state power amps in black and silver bristling with heatsinks, single-ended triode amps with their glow reflecting from bronze or wood panels, MCPU/DSP-centered devices with sleek, flat cases and intimidating remote controls, etc.

Back in 1992, Robert Harley's Stereophile review of the McCormack DNA-1 and Parasound HCA-2200 amplifiers (April 1992, Vol.15 No.4) and the accompanying technical measurements piqued my interest. So, with great curiosity, I arranged to borrow a DNA-1 to audition, along with competitive amps from Aragon, Bryston, and PS Audio. They were all a leap ahead of my Adcom GFA-555, but it took an act of great courage to accept that, despite its less-than-stellar measured performance, the DNA-1 was my favorite. The bottom line was that the DNA-1 excelled at driving my Apogee Duettas to make lively and harmonically pure sounds. I bought my McCormack DNA-1 amplifier before I began reviewing equipment for Stereophile, and it still occupies an honored place in my system.

Bright April Sunday sunshine beams through the bay window of my listening room. The light catches four loudspeakers on stands, two stacks of electronic equipment, a small video monitor, black cables strung behind furniture, and a pile of freshly opened DVDs. I sit in the center in a large, overstuffed chair covered in blue velvet, listening to an array of six loudspeakers and a TV monitor playing The Haunting's DTS soundtrack. The floor rumbles as the sounds of creaking timbers come up from below.

With its latest series of FPB (Full Power Balanced) amplifiers, Krell is taking careful aim at the seam between classic high-power two-channel systems and quality multi-channel installations where sound is yet paramount. Nevertheless, Krell founder Dan D'Agostino was adamant: Krell's Class A components were designed for music playback. "I'm a purist, like you, Jonathan!" he told me.

Nothing like scarcity to create demand, right? Well, there's been a scarcity of Nuvistors out there for decades, and hardly any demand. Do you know about the Nuvistor, aka the 6CW4? It was a tiny triode tube smaller than your average phono cartridge. Enclosing its vacuum in metal rather than glass, the Nuvistor was designed as a long-lived, highly linear device with low heat, low microphony, and low noise---all of which it needed to have any hope of competing in the brave new solid-state world emerging when RCA introduced it in the 1960s.

Recently I found myself on the phone with Linn's chief design engineer, Bill Miller, talking about switch-mode power supplies. Affable Mr. Miller was ensconced in Linn HQ in Glasgow, Scotland. After a bit I inquired if Head Man Ivor Tiefenbrun was about the manse, and was quickly handed over. "You're such a cheeky guy. Why'd you call it the Klimax?"

My father could not resist buying electronic and photographic gear. As soon as he heard about a new Polaroid camera, or a new weather radio, tape recorder, or color television, he'd go shopping. He'd be even more eager to buy an updated version of what he already had, particularly if this meant there was a story to tell. He'd buy one for himself, and sometimes he'd give me and my three brothers one of our own for a birthday or Christmas gift. (I often thought he took more pleasure from giving to us than he did from getting his own.)

I've heard my share of Krells, Levinsons, Rowlands, and the like in other people's systems—expensive solid-state amplifiers are not my usual beat. With the exception of an inexpensive Adcom a few years back, for more than a decade I've owned and reviewed only tube amps. In fact, until the $7500 Ayre Acoustics V-1 showed up, I'd not had one in my system. Similarly, I'd had only tube preamps until I reviewed the Ayre K-3, which so impressed me that I asked to hear the more expensive K-1—and ended up buying it.

What fascinates me about the High End are the electric personalities behind it. Manufacturers typically invest so much of themselves in the products they make. It's a divine madness—they do it because they have to. They're driven to it with a real sense of mission and excellence. But God forbid you criticize any of their offspring...ooo-la-la!

I first saw and heard SimAudio's Moon amp and preamp at WCES two years back, and something about their aesthetics appealed to me: Canadian ruggedness coupled with a decidedly French panache. I remember that those attributes also characterized the demo's sound, although I can't recall the speakers or the sources involved. At succeeding shows, it gradually dawned on me that the Moon components were the fixed elements in a succession of impressive demos.

How much power do you really need? How much power can you actually use? What's necessary, and what's icing on the cake? And does anyone really need 1000Wpc?
