Hi Audioman,
I have the Mundorf Caps SIO in my Pendragons along with the Mundorf Supreme Resistors and I did find the break in process to be very long and not so pleasant at times as has another friend of mine with the same set up. And yes the improvement over the stock Caps and Resisitors was quite dramatic. However, now they are really singing. I am equally impressed with these speakers with a 2 watt Decware Zen and an 18 Watt AN 211. Hopefully I won't regret my decision to sell these in the hope of "upgrading"..........:)
