Consider the plight of solid-state muscle amps. Often derided as brutes lacking sophistication or subtlety, particularly by the SET set (ie, fans of single-ended triodes), these powerhouses are taken for granted and often, like Rodney Dangerfield, they get no respect. And once upon a time, the stereotypes were true. Every veteran audiophile has at some time heard an immensely powerful transistor amp that had the soft sonic allure of a sheet of sandpaper, a lumbering oaf of a component with nothing whatsoever to recommend it save for a bulging set of mighty moose muscles.
For better or for worse, appearances can make a profound first impression. Think of the bold, muscular curves of an Audi TT coupe, the planes and facets of a Lamborghini Murcielago, the sleek lines of a Gulfstream jet. In these vehicles, function and art are combined with smooth facility and perfect aesthetic balance.
Monoblock power amplifiers seem to be moving in and out of my listening room faster than green-onion salsa from Chi-Chi's. Over the past six months I've had the Parasound Halo JC-1, the Halcro dm68, the Pass XA-160, the Musical Fidelity kW, and now these 300W (into 8 ohms), $4500-each beauties from Theta Digital. All of these amps sounded as different as they looked, which was no surprise; too bad the "measures the same, sounds the same" dogmatists remain open for business.
For me, the iconic Adcom power amplifier was the GFA-555. As an aspiring audiophile, I was deeply impressed with Tony Cordesman's review in Stereophile in 1985 (Vol.8 No.4). That did it! After years of kit-building and doing it myself, the '555 was the first factory-built amp that I wanted and could afford. Over the years, I changed speakers several times, and even added a fully regulated power supply to the '555, but it never balked. At the end of its tenure at my house, it had been demoted to my third-string backup; today it's making someone else tap his toes.
Thoughts of power, domination, and audio road-rage enter one's mind when contemplating Musical Fidelity's SUV-like, limited-edition, 20th-anniversary offerings (footnote 1). (Only 75 sets of kWPs and kWs will be made.) The gleaming, brushed-aluminum, two-box, oversized, overweight Tri-Vista kWP preamp is fortress-like—the "kWP" looks as if chiseled into the faceplate by grimy, sweaty hands. Each of its boxes weighs almost 56 lbs. The unit's milled-aluminum remote control, the size of a Volkswagen Microbus and looking like something Fred Flintstone might wield, must weigh over 5 lbs. The kWP outputs more juice than many power amps: 55V, with 20 amps of peak-peak instantaneous current!
Before the advent of big-screen projection televisions, manhood was measured more conventionally: by the size of one's crate-sized, boat-anchor-heavy, brushed-aluminum-fronted power amplifiers. Those days are long gone.
Let's start with some music—three discs I recently have been using to evaluate equipment as well as listen to for enjoyment. They are as contrasting in style as one could hope for, but all on an enviably high musical plane. (Space considerations compel brevity approaching that necessary to sell screenplays to producers at cocktail parties, footnote 1)
It doesn't take much to read between the lines of Sony's discontinuation of the TA-P9000ES analog preamplifier and their introduction of the SCD-XA9000ES SACD player with IEEE1394 digital output at Home Entertainment 2003. (A similar feature from the DVD-Audio camp has been promised.) Surely, we will at long last be able to have external digital processing and DACs in our preamp or control units. In addition to the freedom to mix and match components, this opens the door to having a single digital component manage bass and channel balance for all sources, and room/speaker correction without redundant redigitization.
All high-end audio companies turn over their product lines periodically. Even those amplifiers I have depended on as references go out of production. Although my reference amplifier can remain a part of the reviewing sequence, readers won't be able to purchase a discontinued model and get the results I describe. Thus I am compelled to get a review sample of a new amplifier or speaker, and hope for the best.
Have you ever had one of those conversations with your Significant Other that begins "But I thought you said..." and goes downhill from there? The Other's tone is condescending, and the body language—hands on hips, head slightly tilted—lets you know you're in big trouble.
How did Michael Jordan, talented as he was at the peak of his powers, always manage to impose his will on his teammates to push them to victory when it counted most? What made Sandy Koufax able to elevate his pitching to a superhuman level when the stakes were highest? A knowledgeable, hardcore sports fan can watch the performance of two players with nearly identical statistics and, after not too long, tell you which one is merely very good and which one is great. What makes a star are intangibles—those qualities you can't quantify or analyze, but can't help but recognize when you're in their presence.
Thirty years ago, the upstart audio company NAD revolutionized the manufacturing of consumer-electronics components by "internationalizing" the process. Instead of physically making products, NAD hired a project team in one location to design a product that was then built at a sub-contracted factory located elsewhere. The arrangement allowed NAD to go into business with relatively little capital outlay and low overhead. Other companies have since copied this ingenious business model, and, as transportation and communication have improved, doing so has become easier and more efficient. It has brought prices down and quality up—mostly in the low and middle segments of the high-end audio and video markets.
Modern hi-fi is little more than a way of getting electricity to pretend that it's music. Of course, good source components remain all-important, and even if loudspeakers are imperfect, most of us can find one or two that suit our tastes, if not our rooms and the rest of our gear.
Talking to fellow audiophiles, I sometimes hear generalizations about power-amplifier design: "High-power amplifiers don't sound as good as low-power amplifiers." "Tube amps are more musical than solid-state amps." "Class-A circuit designs always sound better than class-AB." "Bridged amplifiers don't image precisely, throw deep soundstages, or have the transparency of non-bridged output stages." Etc.
