Thanks for the great advice about the variation in theresponse of the bass to loading. I have tended to listen to the highs, e.g. avoiding excessive brightness and edginess with high loadings. I have often started with the 20x - 25x priciple for loading relative to the output impedance. To be honest, this has been one of the best predictors for getting fairly close. Also, I rarely fool with resistors in parallel. I have broad selection of resistors (albeit different brands hence different character), mainly in the 40-1000 ohm range that I can usually define a good and fairly narrow window for loading. Sometimes I will use resistors in parallel just to get to a better defined loading. In the end, I have gravitated to ordering Vishay's resistors that appear in the middle of the desired window. These have been the most neutral and transparent from my listening and generally very satifactory.
