GRYPHON在放大器设计上颇具心得,除了Sonata Special Edition、Antileon、Antileon Solo重量级前后级放大器外,TABU系列CD、合并式及前后级放大器则是它最平价的机种。近期,贵丰又推出了带合并式型号的Callisto系列,其中2100、2200为两款合并式放大器,它们的外型设计十分前卫,强调线条的棱角与质感,让人耳目一新。
贵丰Callisto 2200是一款相对于2100功率更大的合并式放大器,面板上没有旋钮,各种控制可通过按键或遥控完成。它的前级输入采用了BB公司出品的OP2604运放,音量控制为马达驱动金属带状可变电阻方式的ALPS电位器,功率放大部分由分离元件组成,左右声道完全独立,末级各采用了4对三肯2SA1216/2SC2922功率管。该机在电源部分也十分重料,采用了独立绕组的一只大型变压器,左右声道分别通过金封整流桥整流,各用了12只大型电解电容,容量达50000余微法。同时机脚为二前一后的三角式发烧级设计,后方一脚为锥状,对于声音表现会产生有利的影响。值得一提的是该机的遥控器十分新颖,柱形机体棱角上的圆形按键及前方多角形的支架加上十分精细的工艺,使其如同艺术品一般。
