Try it without the Tacima, see what you think. IME they can change the sound but they don't necessarily improve sound quality. I used to have a Belkin and I preferred the sound with it in the system, it gave a very pleasant sense of sharpness and clarity to the midrange. But I reckon it was a benign distortion, not a genuine improvement.

I also had a balanced mains unit for a bit, again it changed the sound but it wasn't an improvement. To me the sound was better without it.

You could also try with your amplifier plugged straight into the wall and everything else into the Tacima. You can degrade the sound of an amplifier by running it through a mains block or conditioner, although this seems to depend somewhat on the amp/speaker relationship and perhaps the specific block in question.
