In our February 2019 issue, when I reviewed a new integrated amplifier from Colorado-based Ayre Acoustics, I concluded that "the EX-8 Integrated Hub is a high-end contender at a competitive price" (footnote 1). In that review I promised a Follow-Up in which I would compare the EX-8 with Cambridge Audio's Edge A integrated amplifier, which Ken Micallef had positively reviewed in our January 2019 issue (footnote 2). While I'd enjoyed my time with the EX-8, I'd found its balance rather on the light side, and that it projected voices somewhat forward on the soundstage.

In the November 2018 issue of Stereophile, Jim Austin reviewed PS Audio's DirectStream Power Plant P20 AC regenerator ($9999). PS Audio had sent me the less expensive DirectStream Power Plant 12 ($4999), hence this review.

Why use an AC regenerator rather than plugging components straight into the wall?

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.
