I am a big fan of Sommer cables in general; I believe they have the best price/value ratio possible.
I am using a Sommer Orbit 240 mk2 for my speakers and I had Sommer Carbokab as my interconnect cable - I have replaced the Carbokab with the Epilogue.
I must say I got totally surprised by the difference it makes!
The biggest difference is in the soundstage: the individual instruments sound more separate and are positioned more precisely (both in the depth and width of the stage)
Vocals also sound more realistic; bass is tight, detailed and focused.
If you don't believe a cable can make a difference buy this one and be surprised! :)
Note: it needs burn-in; especially for the bass to get the final characteristics
