In my last column, in November 2011, I mentioned that preamplifier-processors are generally at a price disadvantage in comparison to the same manufacturer's A/V receivers. The economies of scale almost ensure this. Typically, to design a pre-pro, a manufacturer uses one of its AVR models as a platform; the result is most distinguished from its parent AVR by its lack of power amplifiers.

It was 20 years ago today that Sgt. Michaelson taught the band to play. I was living in London when Antony Michaelson launched Musical Fidelity in an attempt to make a major statement in the area of affordable, high-quality, high-value electronics. Other Brits at the time were doing the same—companies such as Creek, A&R Cambridge (now Arcam), and DNM began to compete for the destitute audiophile's dollar.

The old advertising jingle "Who put eight great tomatoes in that itty-bitty can?" bubbled through my head as Musical Fidelity's Antony Michaelson proudly unboxed the new $4500 M3 Nu-Vista integrated amplifier. How did they cram it all in there?

Specialization seems to be an inevitable consequence of progress: As the products of man and God become more and more complex, they're called on to do fewer things in more focused ways.

My first trip to a Consumer Electronics Show, in January 2010, was an eye-opener. Not only had I never before seen the phony glories of Las Vegas, it was the first time I'd been to a high-end audio show. Between the offerings on the top floors of the Venetian and T.H.E. Show at the Flamingo, I met some great people and heard some wonderful new products. One of those people was distributor Kevin Deal, and one of those new products was from Mystère. Though I was familiar with the PrimaLuna line that Deal also distributes, Mystère was, well, a mystery. However, after a listen to the Mystère pa21 power amplifier making a pair of MartinLogan speakers sing, and after noting the reasonable prices for some of Mystère's beautifully designed and built amps, I put Mystère in my review queue.

At the extreme high end—Halcro, VTL, Boulder, etc.—reviewers gush about a lack of character. If you're paying $20,000, you want a preamplifier or power amp to disappear. At those price points we also want extreme, unfatiguing resolution, and noise that's well below what most people would consider audible. But at those prices, an absence of character is definitely something most people aspire to.

NAD has been out there on the leading edge of entry-level high-end sound long enough that some audiophiles reckon they invented the category. Sure, we should give serious props to the likes of Creek, Rotel, Musical Fidelity, Arcam, Denon, and Parasound, all of which have made significant contributions to the musical aspirations of budget-conscious pilgrims. But I continue to harbor warm feelings about my last extended visit with an NAD component: the inexpensive yet supremely musical L40 CD Receiver, which I reviewed in the June 2000 Stereophile.

In the mornings, just before I leave for work, I power up the system, turn the volume down low, and set the CD player to Repeat. I like to think that if I play calm, soothing music while Ms. Little and I are away, the cats will feel less alone and more relaxed. It's also nice, on returning home from work, to walk into a room filled with music. One evening a few weeks ago, I stepped into the apartment, dropped my bags to the floor, settled down into the couch with my iPhone, and began scrolling through text messages. I'd been seated for only a moment before I had to turn my attention entirely to the sound of the system, which, even at a very low volume, sounded warm, detailed, and unusually good—unbelievably, almost unbearably engaging.

A decade ago, many predicted that amplifiers with switching or class-D1 output stages would come to dominate high-end audio. In a post–Peak Oil world in which the price of energy would always continue to rise, a class-D amplifier's very high efficiency in converting AC from the wall outlet into speaker-driving power would be a killer benefit. Although a conventional push-pull class-B amplifier has a theoretical efficiency of 78.5%, which would seem usefully high, this efficiency is obtained only at the onset of clipping; the need for the output devices to carry a standing bias current reduces that efficiency considerably, typically to around 50%. Class-A amplifiers are even less efficient, with a maximum of 25%; ie, three times as much power is dissipated by the amplifier as waste heat as is used to drive the loudspeaker (see "Sam's Space" in this issue).

Older audiophiles remember the splash NAD made in the late 1970s with the introduction of their 3020 integrated amplifier ($175). Ridiculously cheap, it looked graceful and sounded warm, inviting, and holographic. Removable jumpers between the 3020's sections permitted enthusiasts to determine whether the magic resided in its preamp, its power amp, or in some synergy of both.

Some among us remember a time when audio was divided into rival interests. On the left side of the pond was the New World, where left-brainers believed that vanishing harmonic distortion meant that "all amplifiers sound the same," and that good loudspeakers are a high-fidelity audio system's most important components. Across the waves, so-called flat-earthers claimed that the most important part of the playback chain was the turntable. (Of secondary importance were the tonearm and cartridge, followed by the preamp and amplifier. Loudspeakers were deemed relatively unimportant.) In the 1980s, this extremist idea of the "front end first" captured the imaginations of audiophiles, mostly in the Mother Country.

The $395 NAIT, rated at 20Wpc, is a good-sounding little amp. It's very open and spacious-sounding, but, like the $250 Rotel RA-820BX, sometimes sounds a little hard in the upper registers.

"We've tried making it more powerful. When I was away on holiday, some of our people cooked up a more powerful version and presented it to me on my return. It sounded awful."

In an industry whose newest products are often as discouragingly unaffordable as they are short of the sonic mark, the Naim Audio Uniti ($3795) stands out. In a single reasonably sized box, the Uniti combines the guts of Naim's Nait 5i integrated amplifier and CD5i CD player with various additional sources: an FM/DAB tuner, and interfaces for an iPod, a USB memory stick, an iRadio, and a UPnP-compatible connected computer or server—all for the price of a very good television set.

In a world of me-too products, NuForce distinguishes itself from all those other components whose names begin with i by actually using a capital I. Actually, that statement is unkind, even unfair—unlike the myriads of products designed to capitalize on the Apple iPod's current sexiness, the NuForce Icon isn't designed to be portable (although NuForce does offer an Icon Mobile). What the Icon unquestionably is is a fine little piece of audio engineering, which most of those other i components are not.
