Hi Doug and Richard,
I do not like stepped attenuators (not pleasant !).
I have tried shunt pot mod on another preamp with cheaper pot and it works fine. On my M3 I did not try it because I am satisfied of the
TKD and I did not want to have volume limitation and impedance changes
but you can try it on your preamp it is very easy to do.

  I have done it on a AES DJH Sig. with Caddock resisters, and all it does is reduce the volume by a few dbs. It still doesn't make the pot as useable as a 24 step attenuator. Plus the precision and sound quality of the attenuator is superior.

  Gilbert and Richard, thanks for your responses. The shunt pot mod intriques me, and I may try that before going forward with any other changes. Richard, have you tried the AN tantalum resistor in this position to hear it's impact?

  Gilbert, what did you find unpleasant about stepped attenuators? Was it operational, sonic, or ?

  Thanks again for your replys,
  Doug

    well i finally got round to replacing the metal film resistors i had used in the shunt pot mod with AN tants
    
    was surprised to notice a big difference for changing one resistor. much less nasty top and much more lovely midrange and bass tone

    No it's just a matter of precision between 2 steps and
    less pleasant to operate.
