Budget Component Reviews

If you've ever dipped your toe into some form of high-performance motor sport, you know: The best race-car engines spin torque and exhale horsepower—with intoxicating ease. They're engineered to be responsive. Depress the clutch, toe the throttle, and watch the tachometer instantly pin itself. Engage the clutch—your chest contracts and your head gets light. Then later . . .

Back in your Ford Fiesta, its revving engine sounds distant, muffled. Your body can't feel the powerplant's power. In gear, the Ford feels soft and hesitant, not responsive.

A few issues back, in my review of the Mark Levinson No.26 and No.20 (May 1988, Vol.11 No.5), I mused on the fact that the preamplifier, being the heart of a system, had a more significant effect on sound quality in the long term than, say, the loudspeakers. It was worth spending more on a preamplifier, therefore, than on loudspeakers. Needless to say, this viewpoint was regarded by many readers as dangerously heretical. I decided, therefore, to investigate the sonic possibilities of budget-priced preamps in this issue, even the most expensive being less than one-tenth the price of the Mark Levinson.

The original PS Audio Sprout, which I reviewed in the May 2015 issue, showed newcomers an easier, smaller way to amplify music recordings in the home. At $599, the Sprout100 costs $100 more. It fixes a few of the old Sprout's weirdnesses: no power-on indicator light, no remote control, five-way binding posts that weren't really five-way. It also doubles the Sprout's class-D power output into 4 ohms, from 50 to 100Wpc (or 50Wpc into 8 ohms), and adds a few sonic and mechanical enhancements.

I got an e-mail last summer from my colleague Tyll Hertsens, editor of our InnerFidelity website. "Recently reviewed and really liked the new MrSpeakers Æon," he wrote. "They're a little rough-sounding as sealed headphones tend to be, but the tonal balance is superb. I got three in for review to make sure they're consistent. After measurements I asked [MrSpeakers'] Dan Clark if I could forward them to you because I like them so much and thought you should hear them. . . . I really think you may enjoy them."

For audiophiles of a certain age, the mere mention of NAD Electronics' original 3020 integrated amplifier (1980, designed by Erik Edvardsen), or Adcom's GFA-555 stereo power amplifier (1985, designed by Nelson Pass), conjures up happy memories of audio's last Golden Age—an idyllic time when working stiffs could luxuriate in the same audio arcadia as bankers and brokers. Since then, few, if any, audio components have achieved that level of iconic high value. Which caused me to wonder: What would it take, nowadays, to manufacture a genuinely high-value audiophile product: one that delivers exciting, satisfying sound at a price most audiophiles can afford?

Have I told you about my objectivist friend—the left-brain audiophile who puts a lot of trust in measurements? He has a high natural intelligence and is an extremely experienced listener, but once he knows a component doesn't measure well, he can never again experience it impartially.

I don't want to embarrass my friend, so in this story I will call him O., for Mr. Objectivity.
