    Chính xác là North Star Design cớ bác Thích
    Con DA này hay tuyệt (cơ của nó em chưa được nghe), con DA này 2 nguồn mà thêm vào ăn volume ghê gớm,
    Cả bộ giá sách đâu 4000$

    có lẽ là đơn giản vô địch

    Features:

    * World's smallest number of parts - 9 parts per channel ( excluding attenuators )
    * World's shortest signal pass length - 32 m/m ( including the length of parts )
    * World's shortest NFB loop length - 9 m/m ( including the length of the resistor )
    * World's smallest filter/condenser - 1000µF, (50W version - 2200µF)
    * Powerful voltage regulation with high capacity transformer - 170 VA cut-core transformer +-individual coils
    * Dual mono construction with each channel in a separate chassis.
    * Rigid and compact aluminum chassis construction to release vibrations smoothly.
    * Separate 12-position attenuators for each channel.
    * Can be up-graded into a pair of complete mono amplifiers by adding another Model 4700 Power Humpty.

    Specifications:

    * Output power: 25W+25W ( 8) (50W version : 50W+50W)
    * Input impedance: 22k ( unbalanced only )
    * Attenuators: 12-steps for each channel
    * Output on and off switches for each channel


    Giá sách đâu hơn $5000 cả bộ
