Two boxes, no exotic cabling, no rack of separates - the largest floorstander in Davis Acoustics's Krypton line paired with a single Italian integrated amplifier is about as simple as a serious two-channel system gets. The speaker is the Krypton 9, the French brand's biggest model in the range, driven by the Audio Analogue AAcento, the first product in the company's PureAA series.
The system at a glance
Two components, a domestic living room in the 30 to 50 square metre range, and a combined price well under $10,000, with the Krypton 9 selling for roughly $2,000 to $2,500 per pair depending on finish and the AAcento listing around $5,800. This is a genuinely entry point into serious two-channel listening, built for a buyer who wants Italian amplifier engineering and French driver design rather than a mass-market receiver-and-bookshelf combination.
Why these components work together
The Krypton 9 uses a 28mm fabric-dome tweeter and a 13cm Kevlar midrange common across the whole Krypton range, paired here with two 17cm cellulose-cone woofers in a bass-reflex enclosure, a configuration Davis Acoustics rates for amplifiers in the 150 to 200 watt range. The AAcento delivers 100 watts per channel into 8 ohms, but its 480-watt toroidal transformer lets that figure double to 200 watts into 4 ohms and 300 watts into 2 ohms, so even though its headline 8-ohm number sits below the Krypton 9's stated ceiling, the amplifier's actual current reserve comfortably covers the speaker's real-world impedance dips. Both sides of the pairing share a similar design philosophy - the AAcento is a zero-global-feedback design with no feedback loop from the output stage back to the input section, an approach more commonly associated with valve amplifiers than solid state, and it is built with a genuinely oversized power supply relative to its rated output rather than a minimal one sized just to the spec sheet. The AAcento's built-in MM/MC phono stage also means a turntable can be added directly without a separate phono preamplifier, extending the system's reach without adding another box.
How it sounds
Reviewers of the AAcento consistently describe an organic, three-dimensional presentation with taut, expressive dynamics rather than a thin or clinical solid-state character, and paired with the Krypton 9's Kevlar-and-cellulose driver combination the result leans toward timbre accuracy and a stable, coherent soundstage rather than an artificially forward or bright top end. The Krypton 9's twin woofers give the system a genuine low-frequency foundation for a room of this size, with the sort of clean descent into the bass that lets a two-box system fill a living room without sounding stretched or thin at the frequency extremes
The Davis Acoustic Krypton 9 is the largest floorstanding loudspeaker in the line. In addition to the tweeter and 13-centimeter speaker, common to all models, two low-frequency speakers with a diameter of 17 cm (6.5") are built into the bass reflex. The overall balance of the speaker, associated with a good descent in the lower register, allows you to fill the living room space from 30 to 50 m2 without any disturbances.
The integrated amplifier Audio Analogue AACento is built according to a zero-feedback scheme - both in the preamplification section and in the output stages. The signal circuits use ceramic resistors of increased size - this reduces the total heat. Switching of sources is carried out using electromagnetic relays, and the precision digital volume control (but the signal in chain always remains analog) does not use operational amplifiers. The linear power supply contains a toroidal transformer with a power of 480 watts. Cooling radiators for the output stage transistors are located inside the case.
CD transport based on Teac CD5020A with machined solid aluminum clamp, digital outputs SPDIF Coaxial 75 Ohm and AES/EBU balanced 110 Ohm, and separate power supplies dedicated to control and transport sections.
AADAC works with signals up to 32 bit / 768 Khz via Sabre ES9038 chip and Amanero USB (32 bit / 384 khz). Native DSD up to DSD512 also "on board". Bullet-proof construction uses separate boards for each stage, separate power supplies dedicated to digital and analog sections, and fully balanced output stage.
