High End Vienna 2026 Puts Amplifier Innovation Center Stage
High End Vienna 2026 is a specialist audio exhibition where brands introduce new amplifiers that span Class G, Class A/B, Class D, and emerging GaN technologies for serious home listening systems. This year’s event underlined how diverse modern power solutions have become, from full-width integrated amplifier debut models to compact monoblock amplifier designs and aggressively priced desktop power amps. Across the halls, one theme held everything together: more power and flexibility without abandoning sound quality. The five amplifiers highlighted here cover everything from heritage hi-fi to streaming hubs and architectural audio. Together they show how the market is evolving in several directions at once, with brands targeting different budgets, room sizes, and installation styles while still chasing cleaner, more controlled power delivery.
ARCAM’s A50 Signature and CD25 Extend Radia with Class G Heritage
ARCAM marked its 50th anniversary at High End Vienna 2026 by adding the A50 Signature integrated amplifier and CD25 CD player to the Radia Series, a clear nod to the classic A60 while updating connectivity and system integration. The A50 Signature is billed as ARCAM’s most advanced integrated amplifier to date and continues the brand’s commitment to Class G amplifier design, which switches between power rails to keep distortion low and efficiency high. According to ARCAM’s launch coverage, the A50 Signature and CD25 "extend the Radia Series upward" to serve as new flagships for amplification and silver-disc playback. The pairing appeals to listeners who still value physical media but want modern digital inputs and control, and it signals that Class G amplifier thinking remains central to ARCAM’s identity even as the company reworks its styling and product tiers.
Cambridge Audio Evo 300: 300-Watt Streaming Hub with NCOREx Power
Cambridge Audio used High End Vienna 2026 to unveil the Evo 300, a streaming integrated amplifier debut that turns the Evo concept into a 300-watt-per-channel heavyweight. Built around a Hypex NCOREx Class D stage in a dual-mono layout, the Evo 300 is aimed at larger rooms and demanding loudspeakers while keeping the sleek, one-box form factor. Cambridge highlights the balanced preamplifier stage, separate analog volume controls per channel, and a switch-mode power supply tuned for stability under heavy loads. StreamMagic Gen 4 handles streaming duties, with support for services like Spotify Connect, TIDAL Connect, Qobuz Connect, Amazon Music, Deezer, UPnP, Internet Radio, and Roon Ready operation. In effect, the Evo 300 tries to be both a serious power amplifier and a streaming control center, bridging traditional hi-fi and modern network audio in a single chassis.
Chord ULTIMA 7 and Blade: From Full-Width Power to GaN Class G
Chord Electronics previewed two new stereo power amplifiers at High End Vienna 2026: the ULTIMA 7 and the Blade. The ULTIMA 7 is designed as the most affordable full-width power amplifier in Chord’s range, visually matching the ULTIMA PRE 3 and delivering 135 watts per channel into 8 ohms from the company’s ULTIMA topology. More radical is the Blade, a slim 0.5U GaN power amplifier that uses a Class G architecture and targets custom or architectural audio installations where space and heat management are critical. While full specifications and pricing are being held for a later release, the combination of a traditional rack-sized power amp and a GaN power amplifier in a compact form suggests Chord is broadening its approach. The brand is clearly balancing its digital reputation with fresh analog hardware tailored to both classic stacks and hidden multiroom systems.
Grimm Audio PA1 and FiiO LEVEL 1: From Compact Monoblock to Budget Powerhouse
On the more compact side, Grimm Audio and FiiO each brought distinct amplifier ideas to High End Vienna 2026. The Grimm PA1 is a Class A/B monoblock amplifier rated at 150 watts into 8 ohms and 200 watts into 4 ohms, packing an Amplimo toroidal transformer, a 90,000 µF current buffer, and 96 output transistors into a 9.8 x 9.8 x 9.4 inch, 33-pound cube. It targets high-end systems that want separate monoblock amplifier channels without huge chassis. FiiO’s Jade Audio LEVEL 1, by contrast, is a compact desktop GaN power amplifier built around Texas Instruments’ TPA3255 chip, claiming up to 2 x 300 watts into 4 ohms at under 10% THD+N. Priced at USD 139 (approx. RM650), it offers RCA, USB DAC, coaxial, and Bluetooth 6.0 with SBC and LDAC, making serious speaker power accessible to desktop users and entry-level hi-fi systems.
