High Fidelity: Why the Grimm LS1 is the World's Best Complete Audio System


The Theory One day when looking closely at a copy of the Beatles' first mono single, "Love Me Do" (a replica, sadly), I had an epiphany. You see, my vision is in the extreme nearsighted range, which is mostly a curse but also a blessing because my eyes are like microscopes. The average human eye... Read More »

Devore Fidelity Orangutan O/93 Loudspeakers


As I learned at the recent 2104 New York Audio Show, there is no lack of absurd loudspeaker designs executed with all sorts of wacky and expensive materials. While this year's blessed event was not as off-the-charts as prior shows in regard to loudspeakers that look like they were built by aliens with auditory requirements... Read More »


A High Resolution Music Download Site You May Not Know


Last year there were concerns about the lack of high resolution music files available in the Direct Stream Digital (DSD) format for purchase. It was a factor that some music fans cited as a reason for holding off on buying a Digital to Analog Converter (DAC) that included DSD playback. Those of you following the... Read More »

Impressions: The AURALiC VEGA DSD DAC and TAURUS Mk. II Balanced Headphone Amplifier


The AURALiC VEGA DSD DAC (top) and TAURUS headphone amp (bottom) in tandem, on one of our reference Stillpoints ESS Grid Racks… lovely, lovely! Once, and not so long ago (A year? Two?), I maintained a list of DSD DACs. After the establishment of the DSD-over-PCM (DoP) open standard, and the polishing of ASIO drivers... Read More »


From Clark Johnsen's Diaries: The Polarity Problem Redux, Then Redux Again


More than once this writer has been accused of having a single-track mind when it comes to talking audio. This view I must heartily confute: in fact he has three tracks. But the one that attracts attention foremost does concern polarity, also known as acoustic polarity, also under proper circumstances known as Absolute Polarity. On... Read More »

When Moving Requires That You Scale Down, At Least Temporarily: A Personal Story


"Say it ain't so, I will not go, Turn the lights off, Carry me home" —"All the Small Things", Blink 182 So this all started with a big argument that my girlfriend and I had, the resolution of which was to move in together up in San Francisco, where she already lived. The problem was... Read More »


The Neoteric Listener and The Fritz Hemp 6 Loudspeakers


John (Fritz) Heiler has been designing his Fritz Speakers loudspeakers for over thirty years. His credo is always consistent: He uses the same premium parts as speakers costing much more, and works hard to make affordable speakers that deliver exceptional sound. I've met Fritz many times over the years. He's a really likable, down-to-earth guy,... Read More »

HiFi is All a Scam - Roger Skoff Finally Admits All


That's right, HiFi is a scam, and you, I, and every other audiophile, music lover, and HiFi Crazy have all been laboring under a misapprehension for all these many years. To make it even worse, even those people I've been maligning for so long by, in my innocent ignorance, calling them fools, trolls, "flat-earthers," troglodytes,... Read More »
