In a perfect world, critics would hear a band live then write a review of their new album the following morning. It rarely works out that way, but it just did. The Cookers played Jazz Alley in Seattle last night. This review is underway 12 hours later.

In person, The Cookers, like most jazz bands, are looser and rougher and more expansive than on record. At Jazz Alley…

From the Brahms symphony's soft-edged yet clean and transparent opening, this issue sounds special. As the textures fill out, sonorities expand rather than merely getting louder. The woodwinds' fanfares are crisply placed, yet their soft playing still has presence. Two legato brass chorales in James MacMillan's Larghetto register with satisfying depth…

Editor's Note: The sound of any particular CD transport/digital processor combination will be dependent on the datalink used-see "Bits is Bits?" by Christopher Dunn and Malcolm Omar Hawksford, Stereophile, March 1996, Vol. 19 No.3 (WWW). Unless mentioned, processors are limited to 32/44.1/48kHz sample rates. To be included in Class A+, a digital processor must be capable of handling DSD or 24/96 LPCM data.

exaSound e38 Mk. II (balanced): $4299
The e38 was introduced in 2017 as the third-generation version of exaSound's multichannel DAC, preceded by the e18 and the e28. In 2019, exaSound introduced the e38 MkII, which replaced the ESS ES9028PRO chip of the original e38 with ESS's new ES9038PRO DAC, said to have four times as many internal paralleled DAC channels. There are also redesigned reference voltage sources and master clock power circuits as well as redesigned mainboard and output stages. Reviewing…

Editor's Note: Apart from the Bespoke, CAT, Placette, and Shindo, all the Class A preamplifiers offer balanced inputs and outputs. And unless noted, the preamplifiers listed do not have phono stages.

Editor's Note: Because of the disparity between typical tube and solid-state "sounds," we have split Class A for separate power amplifiers into two subclasses. Nevertheless, even within each subclass, Class A amplifiers differ sufficiently in character that each will shine in an appropriate system. Careful auditioning with your own loudspeakers is therefore essential. Except where stated, output powers are not the specified powers but rather those we measured into an 8 ohm resistive load. All amplifiers are stereo models, except where designated.
