Shielded or unshielded power cables for class-D monoblocks?


I am moving to a new house in Europe where I will be having a dedicated hifi room. Two separate power lines have been installed, still undecided on the wall socket, they will be either Furutech SWS Rhodium NCF or SWS Gold or one of each.

I was thinking of the power cables to my Class D amplifiers (Ncore NC1200 based), for other classes of amplification I normally prefer unshielded power cable but since my amplifiers use SwitchMode power supplies should I try shielded power cables? What do you think?

Strangely I never had luck with Oyaide connectors (their lower end ones) while I like their cables. I think I will try the Viborg gold IECs, they are cheap enough.  I listen mainly to metal and little opera so I need good dynamics, fast transients but at the same time I am very sensitive to sibilance. 

I know what you mean about switch mode power supplies, then again it also depends on the quality of the design of the PSU, its switching frequency, components used, etc but in general they don't sound 'euphoric'.

I hear you guys on separating the power. That is why I am having two separate lines installed one with a duplex wall plug for the power amps and another one with a single wall plug for the front end.  Next thing is what to do with the grounding. Ideally will have a dedicated ground separate from the main house ground just for the hifi but that can be against local regulations and potentially lethal. I need to read more about the Puritan Ground Master, it could just do the job nicely.

You can get some of the NCF performance if you use fo.q damping material from Japan. There are 3 different thicknesses it is piezoelectric and is readily available on eBay. You can treat wayyyy more than your power cords and wall sockets (,Although plenty of gains just here) with 1 pack. 

The thicker stuff is great on flat surfaces,  the thin stuff can go around cables.

Search the forum for uses, I've had 1 pack of ta32 and 1 pack of ta102 from separate sellers. Will be getting more.
Good tip discopants. I have never tried reducing microphonics this way. I have used techflex noise reduction sleeving before and this had minimal effect (but looked cool ;) ) so I kept it anyway.

What is the effect of fo.q on the sound? 

Thanks Discopants. I have never heard of fo.q as my music interests were put on the back burner for few very difficult years. I have used dynomat before to dampen chassis and components but this sounds different. Like Tantejuut asks what is the effect on the sound?
