    Swapped in Buf634 with the 220 ohm resistors attached for the high bandwidth mode. Different level of amp now. Complements the Muses01 opamp, which has the Wima cap mod. It's a tight fit, with the buffers touching the case. It's a good thing, as the buffers get quiet warm and heatsinks onto the chassis.

    Interesting! Can you describe what you're hearing different now?
  3. snellemin
    It has the character of the Cayin c5.

    What kind of resistors did you use and between what pin numbers did you solder them?
  5. snellemin
    The resistor is a 220 ohm value(Vishay Dale). The resistor is connected between pin 1(BW) and pin 4(V-), as can been seen in the pic.

    So can I solder a 220ohm resistor to the side of a 8 pin dip buf634 between pins 1 and 4 and put them in a e12 Diy directly with no adapter, not enough room on my TO-220 buf634's to solder the resistor

    Thanks, perfect!!!! How do you like the 634's with the 01, I have ha-5003 with a 02 and have wanted to try your combo for some time

    I personally like stacked 634's in high bandwidth mode. But it doesn't fit into the diy. With muses it sounds very analog. To my ears with stacked buffers, the sound comes close to the RSA intruder. But I lost most of my audio parts in the massive houston flood, so I can't help you with a direct comparison at this time.
