I owned a set of Piega C-40s for a while...
In my room, they were the worst speaker I ever owned. Overly bright and harsh, small, compressed soundstage, completely unforgiving of all but a handful of recordings.
I was using Goldmund amplification and Piega speaker wires.
I sold them for a song (poorly sung) and was glad to be rid of them. I licked my wounds and went back to a set of Dunlavy Vs. I still own and enjoy the Dunlavy's today.
