2025 Capitol AudioFest Highlights: Alan Taffel on Electronics and Digital Innovations

Explore standout amplifiers, DACs, and streamers unveiled at the 2025 Capitol AudioFest, with expert insights on cutting-edge audio technology.

Each year, Capitol AudioFest (CAF) brings a treasure trove of fresh audio gear, and 2025 was no exception. This time around, power amplifiers and DACs stole much of the spotlight, but a handful of other intriguing devices made their mark too. Whether you’re an audiophile chasing sheer wattage or a tube lover craving lush warmth, this year’s lineup had something special. And remember — all amplifier power ratings here refer to 8-ohm loads.

Amplifiers Bringing Power and Precision

Let's kick things off with some thunderous amps that redefined what power and finesse mean in 2025.

Audionet Schrodinger Monoblock: The Speed Demon

Meet the heavyweight champ of the show: the Audionet Schrodinger monoblock. These beasts, spotted at the GTT room, demand attention — with a price tag of $71,050 for a pair, delivering an impressive 450 watts each into 8 ohms.

But here’s the kicker — speed was the main goal, not just brute force. Featuring a blazing-fast slew rate and a 500kHz bandwidth, the Schrodinger's jaw-dropping damping factor (10,000+) gave the Vivid Gija G3 Cu speakers razor-sharp control and precision. It’s like watching a master conductor wield his baton, every note laser-focused.

Gryphon Antileon Revelation: Class A Powerhouse

Dropping down slightly in price but not in muscle, Gryphon’s Antileon Revelation packs a punch with 160 Class A watts per channel. At $49,800, this amp blurs the usual lines between power and Class A purity. You can opt for a monoblock configuration boasting 180 watts of pure Class A goodness or a stereo setup pushing 165 watts per channel with adjustable bias for Class AB operation when you want a different flavor.

It’s like having your cake and eating it too — no compromises here.

VAC Master 300 iQ Mk II: Versatility Meets Tubes

The ever-friendly Kevin Hayes was on hand showcasing VAC’s new Master 300 iQ Mk II. This $44,000 tube amplifier is a chameleon — you flip switches on the rear and it morphs from stereo to monoblock mode effortlessly.

Native balanced inputs? Check. Single-ended RCA? Also yes. VAC’s signature continuous auto-bias circuit keeps the tubes singing just right. Upgrades over its predecessor include redesigned driver circuits and transformers, offering 320 watts monoblock or 160 watts per channel in stereo. Tube lovers, this one’s a treat.

Linear Tube Audio Century Monoblock: Elevated Elegance

Linear Tube Audio (LTA), known for intimate power, teamed with Sound Lab to birth the Century monoblock. This refined 110-watt amp, crafted with none other than David Berning, balances power and subtlety. Both balanced and single-ended inputs are offered, and with LTA products now sold through Sound Lab’s dealers, this amp is ready to make waves.

Odyssey Meilstein Monoblock: Mountain of Sound

Odyssey climbed new heights with the Meilstein (meaning “mountain” in German), their most powerful and expensive amp yet, ranging from $9,900 to $12,500 per pair. Over four years in the making, this 180-watt monoblock delivers a noticeable leap in dynamics, bass impact, and overall musical oomph compared to Odyssey’s usual lineup.

Linestages and Integrated Amps: Finesse and Flexibility

Audionet Mach Linestage: A Price-Performance Marvel

Only one new linestage made waves at the show: Audionet’s Mach, priced at $37,060. It pairs beautifully with the Schrodinger monoblocks and offers about 95% of its flagship sibling’s sound for 65% of the cost. Crafted by Apple design legend Harmut Esslinger, the Mach blends style and substance effortlessly.

Songer Audio A3 Integrated Amplifier: Smooth as Velvet

Songer Audio’s A3 is a single-ended triode (SET) integrated amplifier delivering a modest but oh-so-satisfying 6 watts per channel from 300B tubes. The $45,000 package features a high-mass chassis to tame vibrations and dual power supplies, resulting in a silky, rich sound that paired perfectly with Songer speakers.

Synthesis Roma 96 DC+ Integrated Amplifier: Italian Flair

Italy’s Synthesis graced the show with the Roma 96 DC+, priced at $4,300 with DAC or $3,600 sans DAC. Powered by EL34 tubes, it pumps out 25 Class A watts and offers interchangeable faceplates — a nice touch of personalization.

Headphone Amplifiers: Intimate Sonic Journeys

CAF has always celebrated headphone culture, and this year’s amps didn’t disappoint.

Two standouts were the Embrace HDP-300B ($6,900) and the Saros Europa ($8,495). The Embrace is unique for rocking 300B tubes typically reserved for speakers, featuring an Italian hand-wound transformer and switchable output impedance to suit a range of headphones. It’s a tube lover’s dream.

Saros Europa, while also tubed, boasts robust bass and soaring highs, shining when paired with Focal Utopia headphones — a combination that simply sang.

DACs: Digital to Analog Brilliance

Lampizator Aphrodite: The Polish Titan

At a staggering $105,000, the Lampizator Aphrodite is a statement DAC with a pentode dual-mono output stage and tube life monitoring. Unique to it is the XDMI input for Taiko music servers and an oversized remote that feels like a spaceship controller. Heard in the Gershman room, it delivered speed, detail, and bass that was easily the best of the show.

SW1X DAC V Classic: Minimalist Magic

British newcomer SW1X unveiled the DAC V Classic at $68,000. Eschewing oversampling, it features four transformers (two silver-wound, two copper-wound), all-silver wiring, and bespoke Black Gate capacitors. This minimalist approach is a refreshing trend in DAC design.

Imersiv D-1 DAC: Pro Meets Consumer

Imersiv’s debut DAC, the $12,000 D-1, comes from pro audio roots (ex-Millenia Media members). It supports HDR-A, enhancing low-level signals, a rare and innovative feature after a decade of development.

Border Patrol ZOLA DAC: Old School Cool

At $3,950, ZOLA DAC bucks trends with no digital filters, no DSD support, copper chassis, and an Analog Devices R-2R resistor DAC chip. Tubed output stage included, it is described as sounding fantastic despite “measuring like a dog’s dinner.” Sometimes, rules are made to be broken.

Streamers and Players: The Digital Gateways

Ideon EOS Stream: Real-Time Streaming Royalty

Ideon’s EOS Stream, priced at $16,000 with 4 or 8TB storage, packs a linear power supply and internal Roon Core (a rarity) for seamless streaming. Real-time streaming with zero buffering makes it a dream for audiophiles seeking flawless playback.

Innuos Stream 3 (with Phoenix DAC Card): Modular Marvel

Arriving fresh from Portugal, the Stream 3 modular streamer/server ($8,000) plus Phoenix DAC card ($4,600) combines for $12,600 total. Heard through Joseph Audio and Doshi gear, it produced nothing short of divine sound quality.

Shanling SCD 3.3 CD/SACD Player: Old School Braveheart

Physical media may be fading, but Shanling’s new $3,999 SCD 3.3 supports CD and SACD, featuring two tubes in the output stage and dual R-2R DACs. It boasts a Sanyo transport now made in China and includes I2S outputs for compatible DACs — a nod to enthusiasts who just can’t quit discs.

Alan Taffel’s Top Picks and Trends at CAF

Best Sound: VAC/Acora Synergy

The VAC 300 iQ Mk II paired with Acora’s flagship VRC speakers ruled the spatiality and resolution game, offering breathtaking depth, imaging, and scale. No other setup matched its musical clarity and presence.

Best Sound (Value): DC Audio Group Tier 2 System

For a shockingly low $1,300, the DC Audio Group's Tier 2 system — featuring HiVi Swan DS 3.1 Mk II speakers, a Wiim Ultra streamer, and SMSL VMV A1Pro amp — delivered refined, dynamic, and full-bodied sound that punched far above its weight class.

Best Demo: IsoAcoustics Gaia Neo Feet

IsoAcoustics’ Gaia Neo speaker isolation feet were a revelation in an easy A/B demo, dramatically broadening soundstage, sharpening imaging, and tightening bass compared to spikes. At $299 a set, they’re a small price for a sonic upgrade.

Most Significant Trend: Tariffs Impacting Prices

Prices across the board have climbed roughly 15% due to tariffs, squeezing an already pricey industry.

Most Coveted: Turnbull Power Distributor

At a jaw-dropping $90,000, this power distributor had ears perked. The real question: what does $90k of power conditioning sound like?

Best Show Joke

Alan Taffel quipped seeing Turnbull’s cables and power distributor in the Tidal room:
“Presumably, they were delivered by armored truck.”
