Powerline Accessory Reviews

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.

Some years ago, I visited the home of a well-known American author who happened to be an audiophile. His cramped, dimly lit listening room contained a tube amp, a DAC, and a pair of inexpensive floorstanding speakers surrounded by what looked like a museum of audio tweaks. I recall a scarecrow-like contraption with swiveling wood-and-metal arms that rearranged magnetic fields, assorted boxes and panels that promoted "quantum proton alignment," mysterious dots covering the walls like a rash, and nearly a dozen things dangling from the speakers' binding posts that were supposed to do something I can't remember. The author had an almost mystical belief in the power of these objects to bend the laws of physics and told me that he'd spent more on them than on the rest of the system, because in his opinion they were more important to the overall sound.

The thing that surprised me most is that despite the tweaks—or maybe because of them—his hi-fi sounded pretty terrific.

In my enthusiastic 2022 review of the Stromtank S-1000 ($16,900), I described the Stromtank as a computer-controlled lithium iron phosphate (LiFePO₄) battery array that, coupled with its AC inverters and all the trimmings, supplies clean, constant, stable off-grid AC power to hi-fi components. By softly depressing a single button on the front panel, Stromtank owners can easily switch from wall-connected mode (when the Stromtank's dimmable front-panel meter is blue) to a disconnected, battery-only state (when the meter is green). At the end of a listening session, users can return to blue mode to recharge the battery array.

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.

The Kingdom of Audiophiledom rests on a paradox. Inanimate audio systems and rooms aim to deliver music that animates our senses and touches our souls. The inherently lifeless exists to bring music to life.

This holistic reality—that systems and rooms function as living organisms where every part is interconnected and interrelated—came home to me when, during one of the first AXPONAs in Chicago, I entered a long, cavernous basement room with several spongy "conference room" walls. "There is no way that any setup can deliver good sound in this room," self said to self. Yet, the system sounded unbelievably good.

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.

Rex Hungerford, Edward DeVito, and Craig Bradley rode into town last week and, together with Audioquest's Garth Powell, solved all the electrical problems that have plagued my audio system for years.
