I don't own the EVO3 Syncro UNI. I own a Titan (used with power amps) and an EVO3 Sigma (source components and linestage). I bought them after hearing a compelling demonstration of their products at a dealership. They make good power products.
My understanding is the the UNI is primarily used to kill DC on the line that would cause transformers, particularly toroidal transformers, to physically emit hum (not hum coming from a speaker). Is this what you are trying to achieve? It is noise coming from the speakers, their other power treatment might be a better choice. At the dealer demonstration, I was impressed with their basic power strip--it reduced most of the noise on the line, with higher up products delivering a smaller increment of improved sound, albeit, at a considerable increase in price. The treatment improves the sound even when there is no actual "noise" that one is hearing in the system.
