Yes, when I decided to upgrade a few crossover parts with Jupiter caps and Path resistors I pretty much committed to keeping them. Since then, I have worked on tweek upgrades and minor room treatments as a way of fine tuning the system. I do realize that the newer models offer cleaner, more precise bass and imaging, but to what degree with the upgrades I've done I do not know.
It is not my goal to have the latest greatest (see my piece on the money onion) and I am very happy with the sound I am getting--I am not hearing any weaknesses in my system. If any of you can solder, consider replacing the cheaper stock resistor with a Path resistor, and/or trying out Tweek Geeks QSA duplex outlets.
Happy listening!
