Setup
In my room, Heretic importer and Fidelis Audio principal Walter Swanbon set the AD614s on custom 12" Fidelis stands about 20" from the wall. In that position, they played big soundstage-wise but were a little lean through the midrange. After he left, I experimented by moving them first forward some, which made them leaner and brighter. So then I tried moving them backward, ending up with the two boxes no more than 6" from the wall behind.

Sitting on the Fidelis stands, the 614's tweeters were 27" from the floor. My normal listening position places my ears 33" to 36"…

Younger people (post-Boomer generations) listen to a ton of music—but are they really listening? Are they paying close attention, or, as the cliché goes, is it, for them, all background music? Generational clichés are rarely accurate. Of course they actually listen. Enough of them are, anyway. And they…

At AXPONA 2022, I eagerly…

I changed brands of speaker cable and interconnects, but inasmuch as I could hear changes, the sound remained dull. To make sure I hadn't inadvertently made some other important change in the system…

Before I tested one of the Esoteric M1X amplifiers, serial number 20014, with my Audio Precision SYS2722, I preconditioned the amplifier, following the CEA's recommendation of operating it at one-eighth the specified power into 8 ohms for 30 minutes. At the end of that time, the internal heatsinks were fairly warm, at 105.7°F (40.8°C), though the top panel's temperature was just 82.6°F (28.1°C). As JVS had told me that the M1X's sound quality improved after a lengthy break-in, I then ran the amplifier at one-third the specified power into 8 ohms for another 30…

Got plans for Saturday afternoon? How 'bout a visit to the dark side? The dark side of the moon, that is—or, rather, The Dark Side of the Moon?

To commemorate the 50th anniversary of that audiophile favorite, music enthusiast Philip O'Hanlon, of audio distributor On a Higher Note (and also MORMusic; MOR is short for Magnum Opus Rediscovered), has organized DSotM listening parties to take place 3–6pm Saturday, 25 March, at hi-fi dens across the USA. If you want to attend, you can (hopefully) find a venue near you at this link. (Scroll and find a location on the US map.)…

Sunny? Spring-y? Even more bizarre: No snow is predicted for the entire weekend of the 34th Montreal Audiofest, which runs from March 24 to March 26.

It always snows during the 'fest. It’s tradition!, like watching the ducks on the rooftop pond leap out of the water to snatch a beak-full of grain before leaping back into their watery trenches. Like people in elevators talking about how nippy it is outside.

There's none of that this time: It was so warm out on Friday that the ducks were floating as nonchalant as duckies bobbing in a (warm) bath. I didn’t hear anything…
