The French-made Kora line has been in and out of American distribution over the past decade. It's currently imported by Norman AV of Aventura, Florida. With the window of opportunity open again, I decided to listen to Kora's modestly priced hybrid integrated amplifier, the Explorer 150SB ($2030).

Based in the Czech Republic, KR Enterprise is headed by an occasionally gruff Dr. Riccardo Kron and his American-born wife, Eunice, who operate the company out of a partially abandoned factory that was once part of the state-owned Tesla High Vacuum Technology facility in Prague. The Swiss-funded company is unique in that it manufactures both amplifiers and the tubes that power them. KR's tubes have found favor with other amplifier makers as well—especially the 300BXS, electrically identical to a standard 300B but rated at 25W in class-A.

Sometimes you have to make peace with a loudspeaker. You have to accept it on its own terms rather than ask it to bend to your sonic wishes, or to be something it's not. This is especially true when you're auditioning a seemingly endless succession of them, as I have this year. Like beauty-pageant contestants parading across the stage, all different-looking yet all enticing in one way or another, each speaker I've listened to of late has sounded different from the rest, and each has had a unique combination of strengths and weaknesses—yet each has been sufficiently "in the pocket" to paint a credible musical picture. Nonetheless, some required more bending on my part than did others, in order for me to believe the musical portraits they were attempting to create.

With the exception of dCS and Accuphase, you don't see anyone jumping on the bandwagon of $15,000-plus SACD players—and for good reason. Despite enthusiasm for the format within the relatively small audiophile community, high-resolution audio isn't exactly making waves on the front pages—or even the back pages—of the mainstream news media. And while ABKCO Records has sold millions of Rolling Stones hybrid SACD/CDs, and Sony is looking to repeat that phenomenon with the recent Dylan hybrids, what's being sold in both cases are CDs, not SACDs. The higher-resolution layer is simply going along for the ride.

No one has ever accused Franc Kuzma of designing glamorous audio jewelry. His turntables and tonearms are industrial-strength examples of engineering know-how and machining excellence. But to those who appreciate such things, his products are truly beautiful, even if they're not adorned with chrome, wood, and sleekly polished surfaces. And if looking at the 4Point tonearm ($6500) in pebbly Darth Vader black doesn't get your analog juices flowing, perhaps its innovative design will. But first, this message:

The lacquers from which LPs are pressed are cut in a straight line, and that's how the LP groove should be traced. Even when set up perfectly, a pivoted arm describes an arc across the disc surface, maintaining tangency to the groove at only two points on that arc. Yet despite numerous attempts at building and selling linear-tracking tonearms, few remain on the market, and most are fraught with technical problems. Linear-tracking arms can be anything but linear, committing more sins of geometry as they meander across the record surface than do their pivoted brethren.

Almost immediately on entering the analog marketplace in 1982, Franc Kuzma, a mechanical engineer based in Slovenia, then part of the former Yugoslavia, established a reputation for manufacturing finely engineered, high-performance products that sold at reasonable prices. Kuzma's early industrial designs, however, while serviceable, looked less than distinguished.

Even as the gulf narrows between the sounds of the best solid-state and the best tubed amplifiers, most listeners remain staunch members of one or the other camp. Similarly, when it comes to video displays, the plasma and liquid-crystal technologies each has its partisans, though that conflict's intensity is relatively mild, perhaps because video performance, unlike audio, is based on a mastering standard that establishes color temperature, gray-scale tracking, color points, and the like (I'm deeply in the plasma camp). But in audio, the "standard" is whatever monitoring loudspeaker and sonic balance the mastering engineer prefers, which makes somewhat questionable the pursuit of "sonic accuracy." Still, in a power amplifier, a relative lack of coloration is preferable to amps that Stereophile editor John Atkinson has characterized as "tone controls"—usually, if not exclusively, of the tubed variety.

In an ideal world, I'd have every phono section I've reviewed in the past 16 years on hand to compare with these three and with all that arrive in the future. But because I have a life, I don't, and I wouldn't even if I could, though some readers (and one retailer) have insisted that that's the only way that I could possibly be of any use to them. Ha! And for those who are concerned that I've neglected the Manley Steelhead, not so! It's still my reference.

The all-FET, class-A, B2B-1 phono preamplifier ($1749), made in the US by Liberty Audio, is beautifully built inside and out, and comes in a heavy-duty aluminum chassis with a baked-on crackle finish and a 3/8"-thick, black-anodized faceplate. The overall build quality and physical appearance suggest something that costs more than $3000, which is probably what it would cost were it sold through retailers and not factory direct. It comes with a two-week return policy.
