Today I soldered in eight Mundorf 0.01uF silver gold oil capacitors for the passive high pass filter, four paralleled per channel.
I was not expecting good results until the capacitors had burnt in for at least 20 hours, The first hour was revelatory, from the off the mid range was far better, bass more defined & extended. After three hours listening it further opened up, individual choir members easily located as well as an improving stage width & depth.
Can't wait to hear what happens during the remaining break-in time. These caps are definitely keepers, leagues better than the original ones.
For 250 uk pounds this is a huge upgrade.
My RS1b is operated with two stereo interconnects, one suited to the bass (copper teflon) and another (silver) for mid/hi amplifiers. The speakers are also modified for biwire operation.
