There's something about Black Ice Audio (formerly Jolida) that puts me in the frame of mind to enjoy some great tunes. It could be CEO Jerred Dunkerson's welcoming demeanor, or it could be the way the company's tube-centric gear renders smooth, eminently listenable sound without costing a fortune.
The demo system in this room featured two sources: On the analog side, a Pure Fidelity Harmony v.2 ($7995) with a Pure Fidelity Stratos cartridge ($1995) fed a Black Ice Audio F159 phono stage ($1875); on the digital side was the Bel Canto Stream 2 network bridge/DAC ($1999). Both were…
There are always a few truly eccentric rooms at audio shows. And at FIAX 2024, the Davina Loudspeaker commanded one.
I first became aware of this speaker system because my hotel room was adjacent to it, and I noticed the unusual intensity of the sound coming through the walls. My first thought was "so this is what it's like to have a bass addict as a neighbor." I am usually the offender when this happens, but I wasn't in Tampa. Anyway, I am drawn to good bass when I hear it, like bugs to a lightbulb.
Once I saw the speaker system and grasped the concept, I knew I had to…
When standalone digital/analog processors made an appearance a quarter-century ago, they were limited to the CD medium's 16 bits of resolution—at best. These days, almost every DAC can process at least 24 bits, and many models offer between 20 and 21 bits of real-world resolution. Modern models from Benchmark, dCS, Merging, Mola Mola, Okto, and Weiss illustrate not just the skill of the circuit designer but also that of the engineer who laid out the printed circuit board.
One of the first digital processors I encountered that offered 21 bits of resolution was the Weiss DAC202, which Erick…
The clarity of the soundstage was just as superb, as I remember from my time with the DAC502. This was particularly evident on a new album of jazz duets produced by erstwhile Stereophile writer Michael Fremer: Rufus Reid Presents Caelan Cardello (16/44.1 WAV files, Liam Records), one of the last albums mastered by Bob Ludwig before he retired. Reid's round-toned double bass and Cardello's Fazioli piano were palpably present in the rather dry club acoustic, the instruments superbly well-defined in both space and tonal balance.
As I was finishing writing this review a few days…

Sidebar 3: Measurements
I measured the Weiss Helios with my Audio Precision SYS2722, repeating some of the tests with the higher-resolution APx555. All the measurements were performed with the Helios's DSP bypassed. Apple's USB Prober utility identified the Helios as "Helios" from "Weiss_Engineering_Ltd." with the serial number string "0.0.1." The USB port operated in the optimal isochronous asynchronous mode, and Apple's AudioMIDI utility revealed that the Helios accepted 32-bit integer data sampled at all rates from 32kHz to 384kHz. The AES3 and coaxial S/PDIF inputs accepted data…
Shunyata Research’s Richard Rogers showed me one of my favorite rooms of the show, a smallish rig that made very biggish sounds.
The source was an Aurender A20 Music Server ($15,000) with a Lumin P1 Network Player ($10,000), a Lumin L2 Music Library ($3500), and a Hegel Viking CD Player ($5000). A Hegel 600 Integrated Amplifier ($12,5000) drove a pair of Clarisys Audio Minuet loudspeakers ($46,000/pair).
The Clarisys ribbon speakers played with excellent timing, naturalness, and lifelike buoyancy and drive that bowled me over then propped me up again, weary as I was on day…
