Back when the CD was a pup, I used to hear people say, "I refuse to buy a CD player until they can record." Ha ha, I thought, smart-ass audiophile that I was, they're gonna wait for a long time—that's never gonna happen. I was half right—it has been a long time coming. But I was also, as my football coach used to insist, half-fast. "Never" has arrived.

Owning a powerful tube amplifier is like owning a classic automobile. Great pleasure may be had, but ownership involves a little more care and maintenance than usual.

Jadis, an audiophile company specializing in all-tube amplifiers and operating out of a small French town, has enjoyed a good reputation for some years, even if some of its models have suffered from the reliability problems that occasionally afflict the largest tube amps. Another problem area is that of power consumption and heat output. In common with class-A amplifiers and high-bias A/B types, including solid-state models, larger tube amps give off substantial heat. The Defy-7's 240W idling consumption may or may not be welcome, according to your location and the season.
