Powerline Accessory Reviews

Are you old enough to remember when the wires connecting speakers to even the most expensive and sophisticated electronics were 16-gauge, multistrand lamp cord, and the terminals on speakers and amplifiers were just little screws? Sometimes those screws wouldn't even secure all of the wires' strands, but as long as loose strands from one screw didn't touch loose strands from the other, it was good enough . . . and back against the wall went your bookshelf speakers.

Their proven success with phono preamps has encouraged Simaudio to now go way upscale: The Moon Evolution 810LP ($12,000) is the company's no-holds-barred entrant in the premium end of the market, and the first phono preamp in its Evolution line of high-end models.

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.

Why am I once again falling down the rabbit hole of alternating current? A while back, I committed to listening to SMc Audio's AC Nexus power conditioner, designed by SMc founder Steve McCormack and distributed by dealer Hi Fi One.

I'm waiting for a bypass.

My heart did not attack me. My arteries aren't clogged. I'm awaiting an electrical bypass to save my audio system's life.

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.

I can't remember a time when I wasn't concerned about power quality. I grew up around finicky, home-brew ham-radio gear and labs full of instruments, and with both, power-conditioning gear was standard fare. When I moved into high-end audio, it seemed obvious that power quality was important. As a result, I've experimented with a wide range of power-conditioning equipment, from simple ferrite loops to huge isolation transformers, and even exotic laboratory power supplies that could vary the voltage, frequency spectrum, and shape of the AC signal.
