Japanese Build Quality, Class A Performance, and Effortless Drive Ability: Luxman L-590AXII Integrated Amplifier Plays with Reference Liquidity, Beautiful Detail, and Big Dynamics
A Highly Commended review from Hi-Fi News, five-star rave from What Hi-Fi?, and five-globe praise from Hi-Fi World agree: The Luxman L-590AXII integrated amplifier plays music with a sound so realistic, it's difficult to hear the difference between reproduction and a live event. What Class-A output stages excel at – midrange liquidity, far-underneath-the-surface low-level detail, stupendous dynamics, full-bloom tonality, stately bandwidth – you get in spades. Under the hood, an ODNF 4.0 drive circuit with a three-parallel pull-push structure, EO-type 615VA "Ultimate Efficiency Power Transformer," and high-capacity block capacitor permit L-590AXII to deliver instantaneous power with unshakeable control. Eight output boards guarantee even the most difficult speaker loads are treated with kid gloves. An onboard MM/MC phonostage, headphone amp, and bypassable tone controls come standard. This is the very audio definition of exquisite, inside and outside.
"[A] sane solution for those who want audiophile performance without any aggravation, save for needing ventilation above the unit. But the real bliss-inducement provided by Luxman's L-590AX II is how it lets you return to hi-fi 's Golden Age, while producing sound to match modern criteria. Me? I'd buy it for the looks and retro features alone."
—Ken Kesser, Hi-Fi News, Highly Commended review
“The original L-550AX was a very good amplifier by market standards, but Luxman have taken all its essential elements and improved on them for the flapship L-590AX MKII. It has more power and detail yet retains the same easy-going musicality and foot-tapping sound. It is an absolute gem.”
Differences Between Luxman L-590AX and L-590AXII
In order to achieve power without sonic compromise, Luxman implemented its ODNF 4.0 drive circuit utilizing a three-parallel push-pull structure with three-stage Darlington. A Luxman 'Ultimate Efficiency Power Transformer' – an EI type rated at 615VA – forms the heart of the amp's power supply, with plentiful regulation ensuring an unshakable response to any load fluctuations. A high-capacity block capacitor contributes to L-590AXII's ability to deliver lashings of power yet remain firmly in control, while the amp's low-impedance transmission design, carefully selected custom components and short, fully optimized signal paths deliver maximum sonic purity. Compared to L-590AXI, which had only four block capacitors, L-590AX MarkII has eight in total – four each for left and right, the same configuration as Luxman's M-700u. Similarly, whereas the L-590AXI had four output boards, the L-590AXII has eight output boards to drive even more difficult speaker loads with ease.
