When I unboxed the Canor Hyperion P1 preamplifier, the four 6922 tubes, two for each channel, were installed, but the 6H30PI dual-triode tubes, labeled "1" and "2," were packed separately. I carefully installed these tubes in the sockets that corresponded to their numbers and checked that the 6922 tubes were correctly seated. I performed a complete set of tests with my Audio Precision SYS2722 system then repeated some of the testing with the magazine's APx500 analyzer.

I immediately encountered a problem in that there was no output from the right channel,…

These days, amplifier design often emphasizes efficiency. Class-D amps in particular have come a long way. Many are terrific, and they're…

Most audio components' capacitors are soldered out of sight, neatly concealed inside the casework. Not the Legacy. Mounted in the silver center bay that runs lengthwise across the top of the amp are six custom capacitors—"pretty maids all in a row," my brain quipped (footnote 6). Each is Ferrari-red and looks like a D-cell that's been hitting the gym. These caps are made in Italy by Itelcond. Along with those logo-shaped heat fins, they've become part of the Pathos look. The company sources smaller, interior capacitors from Italy's ICEL. The input and speaker…

Despite the InPoL Legacy operating partly if not wholly in class-A—which means that increasing the current leaving those 4mm speaker outputs causes the amplifier to cool down rather than heat up—I preconditioned the unit by running it at 10% of the rated 100W/8 ohm output for one hour. Over that period, distortion (fig.1) increased slightly, from ~0.047% to a steady 0.06%; this uplift with temperature is a feature of most low-feedback designs. The distortion is second- and third-order in roughly equal measure.

Amplification by Naim powers these active towers. Each driver gets its own class-AB amplifier: 90W for the tweeter, 130W for the midrange, and 280W for…

The founder/owner of Analogue Productions and longtime blues true believer, Kassem's record label, mail-order warehouse, and vinyl plating and pressing plant—all headquartered in Salina, Kansas—were recently profiled in The New York Times ("The Wizard of Vinyl is in Kansas," March 5, 2025). Among his many business ventures, Kassem is part of the new Craft Recordings vinyl-reissue series…

A friend who sells high-end audio gear once pointed out that people who shop for separate tonearms are very different from those interested in phono cartridges or turntables in general. If you think about it, this makes sense. Almost everyone buying a new turntable needs a cartridge to go with it, and most turntables come equipped with a tonearm. Tonearm shoppers are more avid enthusiasts than general consumers.

It wasn't always that way. In earlier days of high fidelity, 60 or more years ago, people putting together a cutting-edge phono…

It's nice to have a tonearm like the TA-1 where all the adjustments are clear and intuitive and everything moves smoothly and precisely. Tracking force is adjusted using a static-balance counterweight and dial, and the VTA/SRA adjustment uses a basic sliding arm pillar with a locking screw in the arm collar—no fancy on-the-fly VTA adjustment tower here. The antiskate bias is controlled with a calibrated screw-in knob on the side of the bearing housing, so there's no fiddling with weights dangling on fishing line. The supplied tonearm cable plugs into a 5-pin DIN plug at the base of the…
