Kronos Sparata 擁有同樣的Krono Pro 專利技術,反向雙轉盤同步運轉。
SPARTA使用瑞士超精密直流馬達,搭配純A類線性電源供應,達到精確穩定的轉速,再以微處理器控制兩個轉盤的同步,使用反向式雙轉盤設計,採用兩個結構相同的金屬轉盤。 頂部轉盤以順時針方向轉動,下方另一個轉盤則以反方向轉動,兩者同時轉動時,能將那股旋轉動力抵銷,完美的解決晃動問題,令黑膠播放時達到前所未有地穩定。
為求轉動時的摩擦力趨近於零,軸承與軸承套表面都鍍上了一層光滑的鑽石結晶,加上獨家設計的外置式軸承油線設計,號稱全球摩擦力最低的轉盤軸承。
SPARTA分為三層結構,最下層為硬盤設計,上面兩層結合4點式懸吊結構避震,同時有硬盤的堅固穩定以及軟盤的懸吊抑震,再配合上下兩層各有水平儀可供調整,達到了真正平穩均勻的運轉。
SPARTA 保留了KRONOS PRO一切的優點,與PRO相同的極穩重金屬碟壓,並使用獨立的電源供應,使轉盤被電源供應影響的機會降至最低,SPARTA轉速控制器除了控制轉速之外,還可以連接一條光纖線直接照Platter表面就能夠確認轉速。
