  1. #1

    Default CLS IIZ MODIFCATIONS (Complete Overhaul)

    Just for your inspiration I'm posting my modifications that I did for my ML CLS IIz. I used the most exotic parts I could find. Seeing as I will be keeping these speakers forever, this lead me to the belief that they deserved only the best....



    MAIN BOARD

    MAIN SPEAKER CABLES Soldered Directly Onto PCB.

    MUNDORF SUPREME SILVER/OIL (10 Film Caps Soldered Together In-Series).

    E.V.S. GROUND ENHANCER (Hardwired Into Speaker Cable Input).

    ALPHA-CORE Copper Foil Inductors..

    MILLS Non-Magnetic Shielded Resistors.

    12AWG SOLID SILVER JUMPER LINKS (Linking Mills Resistors Onto Board).

    19 GAUGE "PURE SILVER" MAIN JUMPER WIRE (Long Jumper Between Boards).




    POWER SUPPLY PCB

    MILLS WIREWOUND RESISTORS (on Output).

    BNC OUTPUT SOCKETS (Connect to jumper wire).

    MUNDORF SUPREME SILVER/OIL Caps (On ladder).

    VISHAY DIODES (On ladder and elsewhere).

    BLACK GATE (Electrolytic Capacitors).

    NICHICON MUSE Non-Polar (Electrolytic Capacitors).

    IEGO IEC Socket (Solid Silver).

    12AWG PURE SILVER Jumper Wires (Linking IEC Socket Onto Board).

    But how do they sound?
    When I friend changed the Dale Resistors, Inductors, Diodes and went point to point wiring removing the multiple traces from the system board the difference was stunning.

    Large improvement noticed in all areas. 20 PERCENT improvement in Holographic Soundstage. Sounds now appear detach completely from the speakers. Actually produces SOLID ghostly images which can appear in the air, in front and around you. I'm keeping these speakers till my very last days.
