Fortunately, the Cirrus chipset in the AVP-18 offers a potent parametric equalizer. This can be extremely effective: each of the 11 filters for the five main channels permits adjustment of…

In addition, the filters chosen by NuForce's AutoEQ, and confirmed by my ears, revealed very large corrections throughout the midrange and none for the subwoofer. The audible result of all this was a harsh midrange, somewhat boomy but hollow bass, and a strong image shift to the left. Completely unacceptable and inferior to the out-of-box sound before any adjustments to these parameters were made!

What can you tell about the intrinsic sound quality of a loudspeaker if you've heard it only at an audio show? Arguably, not much. If it sounds bad, there may be a number of reasons for that, only one being the speaker itself. It may be the acoustics of the room, problems with speaker setup, poorly matched associated equipment, insufficient break-in/warm-up, or poor choice of demo recordings. Other conditions may not be conducive to the speaker revealing its potential, such as not being able to sit in the sweet spot, being distracted by people talking throughout the demo, etc. You might…
But is it possible for an audio component to be accurate and euphonic? There are certainly speakers out there flying the Accuracy flag that are impressive on first hearing, providing a sense of immediacy and a focus on musical details, but that, on prolonged listening, leave you with a sense of fatigue. I think this is what Gordon was alluding to in his tongue-in-cheek way when he described accuracy as something nobody likes when he hears it. However, while the choices made in the process of designing a speaker often involve trade-offs, I think it's possible for a speaker to be both…

New York-based Chesky Records has just announced its first two MQA-encoded CDs. On May 19, both Camille Thurman's new Inside the Moment and Rebecca Pidgeon's classic The Raven will hit the streets, as it were, with a list price of $18.98. Music lovers with MQA-enabled DACs will be able to experience the full benefits of MQA-encoding/unfolding, while others will enjoy Red Book quality sound.
"The decision to issue these titles as MQA CDs was decided quickly, just 10 days ago, as we were exploring the possibility of working with MQA in our studio," David Chesky explained by phone. "After…
It is almost ten years since I last heard a pair of DCM loudspeakers, the Time Windows made famous by writer Peter Aczel in the first incarnation of his magazine The Audio Critic (foonote 1). The "Time" nomenclature traditionally used by DCM in their models refers to the fact that for any hi-fi component, its performance in the frequency domain is related to, and implicit in, that in the time domain, the two being connected by the mathematics of the Fourier Transform. To put it in simplistic language, a speaker's impulse response can be translated directly into its frequency response: all the…
