We hold these truths to be self-evident, that all men are created equal.
A great conceptsound enough to serve as the foundation for an independent democratic nation.
Yet what's sound in one sphere doesn't necessarily apply to sound in another, namely the rooms in which our systems reside. As much as we audiophiles may wish to declare our independence from room resonances, image smearing from first-order reflections, slap echo, and every other environmental and speaker-related factor that can handicap system performance, no mere declaration will make it so. Not all roomsand not all componentsare created equal.
I was aware that Canadian company Verity Audio, founded in 1995, made loudspeakers, like the Sarastro II that Fred Kaplan reviewed in May 2009. But when Jason Victor Serinus and I attended the 2018 Rocky Mountain Audio Fest, we were both impressed by the sound of an all-Verity system that featured Verity's Monsalvat AMP-60 power amplifier. Jason Victor Serinus favorably reviewed the AMP-60 in May 2019; I didn't have to be asked twice, therefore, if I wanted to review Verity's Montsalvat DAC/PRE (see later).
I have owned the SE version of the Bricasti M1 D/A converter for several years. It's my reference DAC. When, recently, I became aware of the availability of the factory-installed MDx Processor Board upgrade, I packed up the M1SE and sent it off to the Bricasti factory, which is in Shirley, Massachusetts, northwest of Boston. The factory-installed MDx upgrade costs $1000a lot less than the $10,000 it costs today to buy a new M1SE with the MDx board.
The June 2021 issue of Stereophile included followup reviews of two recommended components, both which deserved further investigation of what they had to offer: the dCS Bartók D/A processor and the Schiit Audio Sol turntable.
I have reported on exaSound DACs since the introduction of the e18 in 2013, but those reports were in my Music in the Round column. This is Stereophile's first full review of an exaSound product and the first time one has spent time on JA's test bench.
When Stereophile publishes a followup review in the print magazine, we add it as a "child page" to the website reprint of the original coverage. We have recently done so with three significant products: the Magico M2 loudspeaker, the Linear Tube Audio Z10e tubed headphone amplifier/integrated amplifier, and the Okto Research dac8 PRO multichannel D/A processor.
What I categorize as mainstream, dealer-based, fancy-pants streamers and big-speakers audio is actually only the gold-plated tip of a gigantic asteroid-like monolith that extends (underground) from New York to Hong Kong, from the Arctic Circle to Antarctica.
For his review of the Pink Faun 2.16x music server in the December 2020 issue, Kal Rubinson needed to use a Linux-compatible multichannel D/A processor. A little Googling uncovered the 8-channel dac8 PRO from Okto Research in the Czech Republic, so Kal borrowed one from the manufacturer. He found it to be a great-sounding DAC with an intriguing feature set. He purchased the sample.
Three products are the subjects of lengthy followup reviews in the December issue of Stereophile: MBL's Noble Line N31 CD player-D/A processor, the GoldenEar BRX loudspeaker, and Alta Audio's Alyssa loudspeaker.
For a couple of years, I have been following Prague-based Okto Research. At first, Pavel Krasensky, the founder and hardware developer, offered audio design ideas and DIY modules that I found tantalizing. For example, there was a dandy-looking ESS 9038Pro Sabrebased output module and some appealing power supply modulesbut to use those, the buyer had to manage inputs and integration on their own.
Then, finally, last year, Krasensky released the dac8 PRO, an 8-channel D/A processor with USB input and output, 8 channels of AES/EBU input, and 8 channels of balanced (XLR) analog output as well as a headphone output.
When Stereophile publishes followup reviews of various kinds in the print magazine, we add the followup as a "child page" to the full review. That means that they don't appear on the website's home page and might get missed. The October 2020 issue included three followups: of the Boulder 2108 phono preamplifier, the Weiss DAC502 D/A processor, and the IsoAcoustics Gaia loudspeaker isolation feet.
The email from Herb Reichert was intriguing. "I am, with great difficulty writing about HoloAudio's new two-chassis May DAC," he wrote. "It is death quiet and very natural. It makes every recording sound non-digital."
Once Herb had finished writing his review of the HoloAudio for the August issue's Gramophone Dreams column, I sped to his Bed-Stuy bothy and grabbed the May DAC, both to get it on my test bench and to take a listen for myself.
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.
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."
