Jorma Unity cables are awesome in their price categoriy one will be surprised with the flow, naturalness, space and separation, rich timbres and agree with Mu6 that Unity is never technicall soundng.
Regarding price difference with Prime I think Unity is an excellent choice for most sytems and you will never regret.
Origo line for me is the best cable line around and put to shame most of their competitors. Unity is close.
In my system after a long time of experimentation I choosed al Origo (interconnects and power cords) with Prime speaker cables. My system is hybrid.
I suggest generally Unity in any solid state system and Origo in any tube system.
Mix and match with Jorma cables is working too.
