Integrated Amp Reviews

If you spotted an EICO HF-81 at the local Goodwill, you'd think nothing of this plain-Jane integrated amplifier in its nondescript gray case. But if you kept on walking, you would have passed up one of the best-kept audio secrets of all time. The HF-81 hails from hi-fi's pioneer days, before chromed chassis and slick Mac transformers. It isn't ultracool-looking, like early Marantz or McIntosh gear. It doesn't have the nostalgia factor of a Fisher. It's not a supercheap eBay steal like a Stromberg-Carlson or a Heathkit. So what's the deal?

Yet another of the best systems I've ever heard at a hi-fi show was an exhibit by some former distributors for the English manufacturer Exposure Electronics, at a Chicago Consumer Electronics Show in the late 1980s. The exhibitors seemed to believe it was better to impress with a humble product than to overwhelm with a full-bore assault, because they limited their display to a single amplifier: the then-new Exposure X (as in "10") integrated, mated to a record player comprising a Linn">http://www.stereophile.com/turntables/1103linn">Linn LP12 turntable, Ekoshttp://www.stereophile.com/tonearms/395">Ekos; tonearm, and Troika cartridge, and a pair of Linn Kan loudspeakers.

My first reaction to the Prima Luna Prologue One was based solely on looks: For $1095, I might not have been disappointed had it sounded no better than a Bose Wave Radio. Its casework straddles the breach between vintage and modern in a way that little else does, at any price. The dark gray-blue finish, hand-rubbed to a tactile gloss, wouldn't look out of place on an Alfa GTV (the new one, which resembles a drop of oil). And for the first time in my experience, a high-end audio manufacturer has figured out a way to make a protective tube cage easy to remove and replace: with banana plugs and sockets. Why couldn't one of the high-price American brands have figured that out?
