"I will use the Clarity Caps in the future. I am pretty sure that they are used in the B&W Nautilus speakers (802 and up). I'm not sure if it will make a difference but why not if it is the same price?"
Absolutely! I completely agree. That's the thing that is nice about learning how to solder: One does not have to rely on others to make the choice of capacitor, resistor, or whatever else. I have seen your networks, by the way, and you've done some neat work! My point again was just that we (as a collective) often perceive the sound quality of music differently, and can thus make individual choices about how to go about altering or shaping sounds to our own liking. I've learned to not make cost part of my decision making process, because I have found it unreliable in terms of its relationship to performance. I have used some of the most expensive capacitors available because they sounded best in a given circuit, yet on other occasions chose a very inexpensive part -- but not because of its lower cost. Because it sounded better. The price wasn't even considered.
Another example: The drivers in our two channel system now cost over $2,000/pair for JUST the drivers alone. No cabinet. Our Klipschorns, including a total of six drivers and a like-new pair of complex horn-loaded cabinets were $500 less than that. Of course money comes into play sometimes -- I'm a public school art teacher, after all. I have just found, as far as my own tastes and preferences, that what sounds good to me in terms of passive part selections is not something that is (always) determined by cost in the sense that 'more expensive' universally equates with better performance.
The Clarity caps sound like they might be a great value, and I can tell you are happy with your B&Ws. I know someone who has a pair of B&W monitors in his office system, and I was very impressed by the sound.
