CH Precision's P1 phono preamplifier, which I wrote about in the April 2017 issue, is not going back to its manufacturer. The longer I used it, the more obvious it became that I couldn't part with it, even though I said I couldn't afford it. The cost was stiff even at the accommodation price (at retail, the CH Precision P1 and its optional X1 power supply are $31,000 and $17,000, respectively, footnote 1), but I decided I could afford it, and bought it for myself as a 70th-birthday present. No, I can't hear as well as I did 30 years ago, but my listening is better than ever.

Ortofon (footnote 1), which turns 100 in 2018, launched the original Windfeld cartridge nearly a decade ago. Named for cartridge designer Per Windfeld—who had just retired at age 75, after 30 years with the company—that top-of-the-line cartridge cost $3400 at the time of its introduction.

The AXIOM tonearm from acoustical systems (footnote 1)—the company prefers lowercase—has been on my To-Review list since I spotted it at Munich High End more than a few years ago, but for one reason or another, that never happened. Until now.

Whenever I do turntable-setup seminars, I complain to the participants about the lack of cartridge-pin diameter and clip-opening standards. Anyone who does their own setup has experienced it: The connection is too tight or too loose. Forcing the clip onto the pin usually results in a broken-off clip that most end users don't have the soldering skills needed to repair; in the worst case, it can even result in damage to the cartridge when you try to remove the clip from the pin.

Lublin, Poland, is about 130 miles from Lviv, Ukraine, a town that has been in the news lately. That's about the same distance as Hershey, Pennsylvania, is from my desk in northern New Jersey, where I'm writing this. They are close. Russian missiles struck Lviv on March 18, 2022, and as I write these words Lviv is preparing for more intense bombardment.

The stylus that cuts the grooves in your favorite records is best described, in simple terms, as "chisel-shaped." The most accurate playback styli—the "extreme" ones that extract the maximum amount of information from the grooves—have a similar shape, with sharper and more severe contact edges than a standard elliptical stylus, itself an advance over spherical styli.

Let's get right to it: The best way to set azimuth, as I recently wrote in this space, is to measure crosstalk using either a high-quality voltmeter or a digital oscilloscope and a good test record like Analogue Productions' The Ultimate Analogue Test LP (AAPT1). The traditional, qualitative procedure—setting the headshell so that it's parallel to the record surface—assures only cosmetic satisfaction.
