I have the same interconnects so would be interested in the outcome is any listening tests, as currenly I have not had the time to find a dealer to listen.
On a side note, I also have some RA reference mains cables, but recently tried one of the cleareraudio silver line mains cables. Wow, is the only comment, I had to question whether the RA more expensive cable was actually doing anything. Going back to the default mains cable showed me it still was, hence I bought it in the first place.
But the silver line reduces the back ground noise dramatically and gives everything more realisum, even the new readers on news 24 sound more natural.
While you investigate the interconnect I would recommend you give the silver line a run for it's 60 day home trial.
Good luck on the interconnect. I have rumour 4 cable so would need to look at that also when changing my interconnects, never ending!
For now just expanding my cd collection.
