Digital Processor Reviews

I felt like I'd just been offered a choice of 31 flavors of Baskin-Robbins ice cream topped with up to 57 varieties of Heinz ketchup, 57 condiments, and 47 brands of coddled cream. My head began to spin, my stomach churned, and my mouth grew very dry as I read that Gold Note's DS-10 ($2995) was a "chameleon DAC" with 192 setup options that enable it to "completely blend in with different music genres, giving the listener the opportunity to adapt the behavior of the unit to the music playing, to one's stereo system and, most of all, to the listener's taste."

Hi-fi system resolution has long been the cause of heated arguments. But when it comes to converting digital data to an analog signal, there can be no argument. Data go in at one end of a DAC and an analog signal comes out of the other end, with a noise floor directly rated to the combination of the converter's digital and analog resolution. Ever since I started measuring digital products for Stereophile, I have been expressing a D/A processor's effective resolution in terms of the equivalent number of bits.

This unique device is a solution to a problem that previously couldn't be solved.

There are, of course, any number of little boxes that can extract audio from the HDMI video bitstream; they began to appear on the market to fill a need for a way to route audio from a player's HDMI output In the recent past, you could buy a good-quality—even audiophile-grade—universal player and listen to SACDs via its good-sounding analog outputs. But good-sounding universal players are becoming scarce.

In an era when polar opposites compete as absolutes, it can be a challenge to acknowledge the different and equally valid ways in which audiophiles approach musical truth. But the reality is that our perceptions of how reproduced music should sound are determined, to a large extent, by how we approach the live experience.

Unlike the world of recorded music, where streaming has decimated sales of physical products, book publishing is seeing the reverse trend: sales of eBooks are declining while those of both hardback and paperback books are recovering. I have been a book junkie all my life—the two long walls of my listening room are lined with floor-to-ceiling bookshelves and I have many boxes of books in storage—but these days almost all my book reading is with the Kindle app on my iPad mini.

British digital-audio specialists dCS (Data Conversion Systems) has been on a roll. Since the September 2015 introduction of the Rossini DAC ($23,999), the single-box Rossini Player ($28,499), and the Rossini Clock ($7499), they've released a number of new products and software/firmware updates. In 2016 came network firmware updates that established dCS DACs and Players as Roon endpoints. 2017 brought improved (v1.05) software for the Rossini DAC and Player, and 2018 an update to process MQA, followed by the October 2018 introduction of the Rossini upsampling SACD Transport ($23,500—see John Atkinson's review in the May 2019 Stereophile). Then, in January 2019, dCS released their Rossini v2.0 software, which applies to both the Rossini DAC and the Rossini Player, and which is offered free to Rossini owners.

I first met Pro-Ject Audio Systems' founder and president, Heinz Lichtenegger, in 2016, at the US launch of the Austrian company's The Classic turntable. His passion for all things hi-fi was so intense I thought his head might explode. Gleeful in his mission to bring high-end audio to the people at less than typical high-end prices, Lichtenegger and Pro-Ject can fairly claim bragging rights for their entry-level Debut Carbon (DC) ($460 and up), one of the world's best-selling turntables.
