Solid State Power Amp Reviews

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)

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.

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.
