Mira Ceti 2A3 \u00e4r en stereointegrerad r\u00f6rf\u00f6rst\u00e4rkare byggd runt den klassiska direktupphettade trioden 2A3. Den arbetar i single-ended klass A och levererar ca 2\u00d73 W, vilket \u2013 r\u00e4tt matchad \u2013 ger ett ovanligt rent, naturligt och organiskt ljud med stor n\u00e4rvarok\u00e4nsla. Fezz \u00e4r ett polskt m\u00e4rke som tillh\u00f6r transformator\u00adtillverkaren Toroidy, och en teknisk s\u00e4rpr\u00e4gel \u00e4r att \u00e4ven utg\u00e5ngstransformatorerna \u00e4r toroidala (ovanligt i single-ended-konstruktioner). Det ger l\u00e5g l\u00e4ckfl\u00f6de\/niv\u00e5 av brum, bred bandbredd och fin bas\u00adkontroll.<\/p>\n

Med 2A3 f\u00e5r du den \u201dsublima\u201d triode-estetiken: mycket naturlig klangf\u00e4rg, \u00f6ppenhet i mellanregistret, luft och mikrodynamik, med f\u00f6rbluffande koherens och n\u00e4rvaro. Antagligen tack vare deras utg\u00e5ngstransoforamtorer, s\u00e5 \u00e4r den ”sublim” \u00e4ven i basregistret. Detta g\u00f6r att den \u00e4r verkligt all-round s\u00e5 l\u00e4nge man matchar rumsstorlek och h\u00f6gtalark\u00e4nslighet.<\/p>\n
