Don't know about Epsilons, but Cerulean is a wonderful cable for the money. My system becomes bright when I put in silver cables, so bright I can't listen to string music for more than 10 seconds. Cerulean is able to resolve detail and create air/ambience without sounding bright, something most silver can't do. On top, it has excellent coherence and not lean like most silver. Bottom end is also full and extended with excellent pace and details. In short, I love my 5 meter XLR Cerulean.
The only other cable that I have heard in my system that equals the Cerulean is Audience AU24, but have you checked out a 5 meter XLR AU24 retail recently?
