Jazzonthehudson, In my experience, the U series CT-1's really separate themselves from the 1 and 1E in all aspects of musical reproduction.
everything the first two did, the Ultimate does better- a LOT better.
But Beware… If you listen to these High Dollar speaker cables, you will not want to let go of them.
Also, they take 4-EVERRr to break in fully. sound ok in a week but improves to breathtaking in 2000hrs.
I hope other Ultimate owners will comment on this.
