In Romania in premiera probabil singurul exemplar al acestui ultra rar amplificator de top, comercializat in anii 90 exclusiv pe piata japoneza, care este rar de gasit atat in Japonia cat mai ales in Europa si State.
In stare foarte buna atat estetic cat si tehnic. 30kg greutate! Mici semne inevitabile dupa 32 ani dar nimic deranjant. Vedeti pozele si video demo.

Oportunitate unica pentru colectionarii ultra pretentiosi care vor sa aiba in colectia proprie the Best Ever Integrated from Luxman
In pret se va include un transformator Nissyo SK-550E de la 220V la 100V de putere 550W, 2x consumul maxim al amplifului.

Acest amplificator integrat este apogeul Luxman in materie de integrate in clasa A, fiind totodata si cel mai puternic disponibil in acest segment: 2x50W (8ohm).
Cele facute in anii 2000 nu au mai depasit 2x30W (8 ohm) si nu au mai avut componente custom-made atat de sofisticate si atent gandite in special pentru disparea caldurii degajate in clasa A.
Actualul Luxman L-595 care a preluat designul seriei 570 si care se vinde acum la 12.000 EURO in RO… este tot 2x30W pentru a gestiona cu costuri rezonabile problema inevitabila a disiparii caldurii la o astfel de putere in clasa A.

Luxman L-540 - lansat in 1989 la 240.000 yeni (2x15W la 8 ohm in clasa A apoi in clasa AB pana la 2x100W) - la vanzare pe audioweb
Luxman L-570 - lansat in acelasi an la un pret de 350.000 yeni, doar in clasa A, 2x50W
Luxman L-570X's - lansat in 1992 la pretul de 380.000 yeni, doar in clasa A, 2x50W
Luxman L-570Z's - lansat in 1992 la pretul de 500.000 yeni, doar in clasa A, 2x50W (8ohm) sau 2 x100W (4ohm)

Dupa opinia foarte multor critici - vezi mai jos - in aceasta serie L-540 si L570Z's sunt cele 2 amplificatoare care suna cel mai bine din punct de vedere dinamic. L-570 si chiar L-570X's sunt caracterizate de un sound mult prea soft care nu a fost pe placul audiofililor care isi doreau o alta dinamica de la Luxman.
Ca atare in 1992 s-au facut imbunatatiri notabile in prima faza prin 570X's insa acestea au duse la extrem prin modelul 570Z's pentru care pretul a ajuns la incredibila suma de 500.000 yeni si care suna extrem de dinamic si detaliat, un nivel de low bass nemaiatins de nici un alt integrat de top pe care l-am mai avut pana acum, fie ca ma refer la Luxman (chiar si modernul L-507uXII) sau Sansui seria 9, AU-Alpha907XR, sau separatele high end Victor Laboratories M-L10 si P-L10 etc avand o expresivitate absolut unica, comparabila cu un sistem high end pe separate tot din clasa A evident.

Remarks
The Luxman L-570Z's is another update of the L-570 and was only available in Japan. Customer reactions showed that the sound of the L-570 was too soft for many and that they expected a more dynamic sound in the direction of the L-540. Accordingly, the power supply of the L-570Z was designed to be more dynamic, and various circuits were better designed to avoid the attenuation of dynamic and phase shifts. In addition, the L-570X's partially redesigned circuit boards were further optimized, gold-plated & nitrogen-filled sealed relays were used, the chassis as well as the preamplifier power supply was strengthened, the heat dissipation was now carried out with pure copper heat pipes and the entire interior was redesigned with pure ones Wired with copper cables.
Visually, the Luxman L-570Z's was identical to its two predecessors. However, the new monitor button (this as a visual demarcation) was now made in red.
