This is an interesting article, my thanks to John Atkinson for the opportunity to clarify.

The article shows measurements of A/D and D/A cascades; however, these are not measurements of MQA. The diagram below may clarify.

The diagram shows the structure of a typical MQA Decoder (dotted box), connected to a paired D/A converter. There are two signal paths. In the upper path, when an incoming MQA stream is detected, the MQA decode proceeds, first to unfold to the 'MQA Core' signal (typically at 2x, ie, 88.2 or 96kHz) and then to the MQA…

When I reviewed Apple's HomePod smart speaker for the August 2018 issue, I found Apple's virtual assistant, Siri, less helpful than annoying (if also, at times, amusing). I was very impressed, though, with the sound of this unusual speaker, with its upfiring 4" woofer and array of seven horn-loaded tweeter/midrange drivers. Apple was already planning a software update that would allow two HomePods to be used as a stereo pair, and I'd promised a Follow-Up review when they did.

Mere days after submitting that…

Arvo Pärt is now so popular that it's no longer necessary to explain him. His piety is approachably beautiful and welcoming. He was not born composing his airy, contemplative, trademark "tintinnabular" (bell-like) music; up to the early 1970s, he cut his teeth on the 12-tone scale. His four symphonies, presented here on one CD for the first time, take us through that part of his…

As I write this, my copy deadline is three days away, yet I've succeeded at crafting little more than my heading (easy enough: it's just the product's name, followed by my name) and my Associated Equipment sidebar (also easy), leaving a great expanse of nothing in between. That's mostly because the Kalista DreamPlay One, a two-box CD player whose $43,000 price might once have kept me from even considering it…

Like Rega Research's Apollo CD player, which Art Dudley reviewed in June 2018, the Kalista DreamPlay One has no digital inputs of any kind, which limited my measurement of its technical behavior to using 16-bit test files burned to a CD-R. I tested the Kalista with my Audio Precision SYS2722 system (see the January 2008 "As We See It"), using two of the six reconstruction filters the Kalista offers: AD's preferred filter, the Super Slow Rolloff, and the default filter, Sharp Rolloff.

The Kalista's error correction was good—no interruptions were apparent in…
