An 11-micron-thick ribbon of foil, printed with conductive tracks and weighing fifty times less than a conventional dome, is the driver technology Raidho has built its entire reputation around, and the Danish company's newest TD3.10, hand-finished with eight stages of sanding and sixteen coats of piano lacquer, made its Munich 2025 debut driven by Moon by Simaudio's 861 power amplifier. Hifiverse's own listening report from the show floor called the hour spent with this pairing "one of the highlights of the event."
The system at a glance
Two components, a flagship Danish loudspeaker replacing the well-regarded TD3.8, paired with Canadian amplification built on the pedigree of Simaudio's own Moon 888 reference model, priced at €120,000 to €135,000 per pair depending on finish. The combination is aimed at Raidho's signature planar-magnetic ribbon technology at the top of the company's mid-tier TD range, backed by amplification specifically engineered around distortion-cancellation circuitry.
Why these components work together
The TD3.10 mounts twin 10-inch diamond-coated bass drivers, the largest Raidho has used in any production loudspeaker, alongside two 5.25-inch tantalum-diamond midrange units and the company's proprietary planar-magnetic ribbon tweeter, crossed over using a combination of second- and fourth-order slopes at 240Hz and 2,700Hz, rated at 89dB sensitivity into a 4-ohm load with bass extension to 20Hz. Hifiverse's own review notes that despite Raidho's stated 50-to-300-watt recommended amplifier range, the TD3.10 is current-hungry in practice and rewards a properly powerful partner rather than the lower end of that recommendation. The Moon 861 answers that need directly, built around Simaudio's proprietary Moon Distortion Canceling Amplifier circuit, a topology engineered to suppress distortion and noise to what the company calls an all-time low level, paired with the Moon Damping Base mechanical-isolation system that keeps external vibration from reaching sensitive circuitry. Because the TD3.10's own crossover uses Mundorf air-core inductors and metallised polypropylene capacitors chosen to let the ribbon tweeter's exceptional speed and low mass translate cleanly into the listening room, an amplifier with low self-generated distortion, like the Moon 861, is precisely the kind of partner that doesn't undercut what the ribbon driver is capable of resolving.
How it sounds
Hifiverse's own verdict describes "surgical precision" in soundstage construction combined with a "holographic" rendering of recorded space, alongside a warm, lively and moving character that the reviewers praised for never falling into sterility despite that precision, concluding the TD3.10 "touches the soul" instead of merely impressing on a technical level, an emotional response the Moon 861's low-distortion, vibration-isolated design is engineered not to get in the way of.

TD3.10
The Raidho TD3.10 is a three—band floorstanding loudspeaker with a bass reflex, replacing the highly appreciated TD3.8 model by experts and buyers. The speakers are equipped with two low—frequency drivers with diamond—coated diffusers with a diameter of 10 inches - the largest, according to the company, in serial speakers - paired with a proprietary ribbon tweeter and two midrange drivers TD series.

861
The Moon 861 is a power amplifier based on the pedigree of the outstanding Moon 888 and the holistic design philosophy of the North Collection. The devices of the Northern Collection feature the latest proprietary technologies: Moon Distortion Canceling Amplifier (MDCA), a scheme that suppresses distortion and noise to an all–time low level, Moon Damping Base (MDB), a system of mechanical isolation from vibrations, as well as a new volume control scheme.
