While I find them lovely, this is subjective turf. I can say for sure you will get a true measure of the "North Creek sound" if you just order enough Crescendos to bypass all of your caps and use the 1uF where you can. I feel comfortable with anyone doing that on my recommendation. If you want the whole enchilada thats great, but you will know if you like them with just a bypass. It is true that whatever they are paired with can alter the sound, but you will hear the North Creekness either way. Even if you like something else better, the quality and experience would be worth it. You can also use them like seasonings if, say for instance you were more of a paper oil, or motor run kind of guy. One thing that is loads of fun is to run one of more of the Crescendos backwards. They used to suggest this practice to puff up the mids and smooth out the highs with certain tweeters. It softens the image, but it takes away metal dome sound like crazy to my ears.The point (if there really is one) for using the spread of values is suposedly to avoid the stacking of sonic signature that might occur if one combined a group of the same value and brand of cap. Say a cap had a little sheen in the top octave, another was dark and rolled off sounding. groups or singles of either might sound either in your face or far away. Stacked they might be neutral sounding. While I hear, or believe that I hear this occuring, I wrote it hypothetical for objectivities sake.
