Core Power Deep=Core 1800 Sometimes the job of an audio reviewer is hard.

Not only is there a fundamental debate in the audio world over whether or not these non-audio producing / processing devices... Read More »

Nordost QKORE Ground Products


The telltale sign that everything was right—better-than-right—appeared when I set my CH Precision M1.1 monoblocks to produce a flat response, meaning bass, mids, and treble were output in equal measure, just as they were designed to do at the factory. Previously, I had found it necessary to boost the mids (or lower the treble) to... Read More »


Roon Labs Nucleus Plus Server


Over the past four decades I have had the pleasure of taking my readers through, and helping them understand many different music formats. During the 1970s we saw the compact cassette take over from vinyl records as the dominant format for music consumed at the mass-market level. The compact cassette was then eclipsed by the...

The Pass Labs INT-25 Integrated Amplifier


The Road Goes On Forever...  A long time ago, a wise old soul told me that if folks work hard and save their pennies, they can likely afford to pursue a single spend-iferous hobby during an otherwise humdrum human existence...And although I doubt the veracity of that anecdote, I get where he was going with...

The dCS Bartók DAC - A True Benchmark

The PBN MR! 777 - Of Men, Music, and Mountains


When it comes to projecting a sound-field that images well, especially in this day and age of speaker manufacturing, performance can work in the favor of the smallish speaker. Even very small designs can image like crazy, particularly listened too in the near field. But to truly reach the peak that is live music, a... Read More »


The Zesto Audio Leto Ultra Preamplifier: Premiere!


I am an imaging junkie. Musical images, properly recorded, must have realistic tonality, unwavering stability, a rounded aspect, and—whether vocal or instrumental—must be room-present.
