Bricasti Design M21 D/A processor

Sasha Matson Oct 03, 2025

Those of us who review audio equipment, and even audiophiles who don't, often talk about our reference systems. The term implies a certain level of consistency. If you are changing components every week, your system probably lacks the stability to be a true reference. In the case of reviewers, this presents an irony . . .

CH Precision C10 D/A processor

Jim Austin Sep 25, 2025

It takes audacity for a company that already builds one of the finest DACs on the planet, which is already expensive, to set out to build one that's so much better that it warrants an extra digit in the model number and a much higher price tag. But then CH Precision has never lacked audacity.

Ideon Audio eos D/A processor

Herb Reichert Aug 21, 2025

This review started with a gentle handoff. My ol' pal Walter Swanbon of Fidelis Distribution stopped by Brooklyn to take away the $10,000 Limited Edition Falcon LS3/5a loudspeakers and drop off the $10,000 eos DAC by Ideon. As he was getting in his car, I yelled, "Walter! I'm warning you! If that thing's not plug'n'play, I'll put it right there on that curb."

Weiss DAC204 D/A processor

Robert Schryer Jul 31, 2025

Weiss Engineering D/A processors are widely known for their high quality, in both home-audio and pro-audio circles. Over several Stereophile reviews, they have always measured well. Oh, and did you know they'd won a Grammy Award? Weiss Engineering founder and chief designer Daniel Weiss won the 2021 Grammy Award for Technical Merit for his pioneering work during the '80s and '90s designing digital equipment for mastering studios.

Fezz Equinox D/A processor

Herb Reichert May 30, 2025 First Published: May 30, 2025

It wasn't long ago that bottom-shelf DACs had this dry, gray, punchy, grainy sound, emerging from a weird mechanical clarity. Their sound reminded me of cheap whisky. The ones that didn't sound like $1 shots replaced the dry grain with some blurry gel. No vitality. No subtle contrasts. No nuance. No air. No atmospherics, no reverberance, and nothing I would call transparency.

Digital's rapidly evolving technology made the next wave of DACs sound strikingly clear and quiet, with some touchy-feely hints of wetness to suggest a more natural transparency. Unfortunately, most of these newfangled wet DACs sounded like distilled water tastes.

For me, digital transparency didn't become truly wet, colorful, or naturalistic until I discovered NOS R-2R converters, which made midlevel four-figure DACs, like my Denafrips and HoloAudio, sound like bits bathed in luminosity. Very relaxed. Grainless. Ektachrome.

It was during a visit to my music room by five members of the small Off-Islanders Audio Society that the magic of the dCS Varèse Music System ($267,500 as reviewed; $305,000 with CD/SACD transport) became clear.

One member had requested the 24/192 version of "Splendido Sundance" from Saturday Night in San Francisco (24/192 FLAC, Columbia-Legacy/Qobuz), performed by Al Di Meola, John McLaughlin, and Paco de Lucía and recorded live in the Warfield Theatre on December 6, 1980. I'd attended the unveiling of the LP remastering of this recording, presented by the album's co-executive producer, Abey Fon, in the Audio Reference room at High End Munich 2024. The system, which was first class, included a VPI Titan turntable, D'Agostino Relentless preamplifier and Relentless 800 mono amplifiers, a VTL TP-6.5 Series II Signature phono preamplifier, Wilson Audio XVX loudspeakers, Nordost cabling, a Stromtank power generator, and an unheard three-piece dCS Vivaldi APEX music system.

Ayre Acoustics KX-8 preamplifier

John Atkinson Apr 27, 2025 First Published: Apr 25, 2025

For the past decade or so, I haven't been using a preamplifier. The D/A processors I have been using all have volume controls, so I have been feeding their outputs directly to the power amplifiers. It would seem logical that having nothing in the signal path would have less of a degrading effect than a preamp's input and output sockets, switches, volume control, printed circuit-board traces, and active and passive parts, not to mention an additional pair of interconnects. However, with some of the preamplifiers I have auditioned in my system, there was no doubt that the sound quality improved compared with the direct connection from the digital processor.

The most recent of these preamps was the MBL N11 that Jason Victor Serinus reviewed in July 2021, which was preceded by the Pass Labs XP-32 I reviewed in March 2021, the Benchmark LA4 Kalman Rubinson reviewed in January 2020, and going back even further, the Ayre Acoustics KX-R Twenty I reviewed in December 2014, which was one of the products Ayre released to celebrate its 20th year of operation.

I am now reviewing the KX-8 line preamplifier, which costs $6500 in basic form.

Cambridge EXN100 streaming D/A processor

Tom Fine Apr 08, 2025 First Published: Apr 08, 2025

The marriage of little streaming computers to DACs was at first a shotgun thing, a way to add Swiss Army knife capabilities at a price point. That was back when it was cutting-edge to have a NAS server full of digital files on the home network, and when commercial streaming was new, primitive, and lossy. Remember Pandora? Cool idea, but who wants to sit through ads and not be able to skip over more than a handful of disliked tunes every hour. Then Spotify came along. Then Apple and Amazon jumped in, and that's all she wrote. Eventually, streaming even got around to us audiophiles who desired lossless audio of at least CD resolution. Viva Qobuz!

The EXN100 is Cambridge Audio's state-of-the-art streaming DAC. It's half of the new EX line; the other half is the EXA100 integrated amplifier.

Wattson Audio Madison LE D/A processor

Herb Reichert Mar 27, 2025 First Published: Mar 27, 2025

After it was delivered, I weighed the box containing Wattson Audio's DAC-equipped Madison LE Streamer on my bathroom scale. It was hardly bigger than a shoebox. It weighed 8.3lb.

When I opened the main box, I found two smaller boxes. The little brown one contained a fist-sized power supply in a chassis of extruded aluminum, with a label attached that said "AC/DC Hybrid Adaptor" next to a circle containing a sun cross symbol and the words "Designed, Engineered and Built in Switzerland" in capital letters circling its top edge. Below the circle was more writing: "Wattson Audioa CH Precision company."

The Wattson Madison LE's 2.3lb chassis was inside a larger white box with black block letters saying "Madison." Under that, written in cursive, were the words "Lounge Edition." The L in LE is for Lounge, not Limited as you might expect.

I've reviewed a few DACs but never one this small, light, and elegantly formed.

EMM Labs DA2i D/A processor

Jason Victor Serinus Feb 28, 2025 First Published: Feb 28, 2025

More than five years have passed since I evaluated the original, Canada-made DV2 D/A converter ($30,000 in 2019) from EMM Labs. Since then, I've heard it and other top DACsmany of them at audio shows; some in my reference systemand my appreciation for what the original DV2 could deliver has only increased.

Now arrive two new components, the DV2's twin successors: the DV2i, an "integrated" stereo D/A converter with a software-driven, high-resolution digital volume control, and the subject of this review, the DA2i, a straight D/A with no volume control. Both cost $35,000.
