Gramophone Dreams #40: Denafrips Terminator & Ares II

I am fascinated by DACs and the shifting sands of today's digital-audio marketplace. This month, I am reporting on two more DACs, both made by Denafrips: the $4498 Terminator, until recently their flagship DAC, and the $768 Ares II, the company's least expensive model. Like the HoloAudio May DAC I described last month, both Denafrips converters employ R-2R conversion schemes, and both render recordings into direct, unprocessed sound.

The Denafrips Terminator is not new. It has been around since March 2017 and has been reviewed and discussed (but not in Stereophile). When I checked,…

Gramophone Dreams #40: Denafrips Terminator & Ares II Page 2

The biggest difference between the HoloAudio May and the Denafrips Terminator was that the Terminator felt slightly more vigorous. The sense of a "whole solid piano" was more obvious with the Denafrips. The May DAC, on the other hand, gained an emotional edge with a more distinct rendering of the piano's pitch, temper, and chromatics (especially in OS-DSD—oversampling DSD—mode). The Terminator emphasized a note's shape and body, while the May directed my attention to tone, texture, pedaling, sustain, and the live energy surrounding the instrument. The two DACs were equally forthright and…

Manger s1 active loudspeaker

My first exposure to Manger Audio loudspeakers, which are based on the "bending-wave" technology invented years ago by the company, was to the Manger p2, their passive flagship speaker, at the 2019 AXPONA. I heard it again a month or so later at High End Munich. I was impressed both times, especially by its transient and spatial performance.

I don't remember what music I heard at AXPONA, but in Munich, I asked to hear Duke Ellington's Jazz Party in Stereo, which (despite being first released in mono, as Duke Ellington Jazz Party) is one of the more profoundly stereo issues of its era. The…

Going with the flow, I put on the digital version of the recent Charlie Parker Savoy 10" LP Collection (16/44.1 FLAC, streamed from Qobuz; Art Dudley wrote about the LPs, Craft Recordings CR00010, for Revinylization #5). It sounded like this recording sounds—vintage to be sure but with rich, textured, immediate, impactful horns playing directly into the microphone, bass and drums set farther back, and piano somewhere in the middle sounding clear and articulate, not at all recessed.

Next, I turned to Nathan Milstein's 1954/1956 recording of the Bach Partitas for Solo Violin (EMI Classics…

Yamaha A-S3200 integrated amplifier

Yamaha: The name evokes memories of my youth when those much-coveted receivers were out of financial reach, leading me to rely upon entry-level Kenwoods and Pioneers and others that sounded worse. Everyone who ever had a cheap receiver blow up—that's what caused me to move from Kenwood to Pioneer—or heard an old Akai that made LPs sound like 128kbps MP3s, please raise your hands.

Yamaha was in a different league (footnote 1). Hence, when Jim Austin proposed that I review the brand-new, top-of-theline Yamaha A-S3200 integrated amplifier ($7499.95), I was eager to discover just how far the…

Given that the recording's air and depth is exceptional, and that I could only hear it in full measure when balanced interconnects ran between the dCS Rossini DAC and the A-S3200, I stuck with them save for when I listened, briefly, to the A-S3200 in amplifier-only mode, which required the use of single-ended interconnects from the volume-controlled Rossini DAC.

At first, I used the Rossini DAC's 6V output, which, in my opinion, usually delivers more colorful and nuanced sound than its 2V output. I detected distortion on a number of tracks (footnote 2), so I switched the Rossini to…
