High Fidelity Cables MC-0.5 Effect

I'm looking for some advice please.
Has anyone used/is using a High Fidelity Cables MC-0.5 Power Conditioner?
What are your observations?
I'm looking at possibly getting one.

Have a number of extras already:
- Akiko Triple AC Power Enhancer
- Akiko Audio Fuse Box Tuning Chip
- iFi AC iPurifier
- Russ Andrews 'The Silencer'
- Mad Scientist Nitro power cables
- Signal Ground Solutions Grounding Box
- Bybee iQSE

I'm not looking for comments from those who have not heard this in a system.
