Has anyone upgraded their caps and resistors on the Klipsch RP- 600m? If so which caps and resistors did you go with? I want to tame the piercing highs on the rp600m. I can either get Kimber Kable 8tc speaker cables which are neutral sounding and help with the highs a little bit or just upgrade to some neutral sounding caps(which would help out the brightness even further). I know the Jupiter copper foil paper and wax caps and Jantzen Amber Z-cap are neutral sounding. Both caps will be an upgrade over the stock cap while adding some more detail, lower noise floor aka blacker background and I believe better midrange. The resistor I need to do a little more research on but have it narrowed down to a few brands. If anyone has used these caps on other Klipsch speakers I would like to hear your opinions on them. I will also be upgrading the internal wiring and speaker binding post at the same time.
