Shielded or unshielded power cables for class-D monoblocks?

The amps are driven directly from a Weiss DAC 202 connected with balanced ICs. The front end is currently powered from a power conditioner and I think I will be using shielded power cables there. I currently use DIY supra lorad cables with wattage connector at IEC end and Neutrik power connector. I would like to upgrade them.

The power cables will be almost certainly DIY again, the cable either something from the Furutech range or DIY helix style. For the power amps I was thinking of using the Nanotec 308 wire which seems to be not shielded.

tantejuut , I think you are using the Viborg connectors, how do they compare to the Furutech ones? Which ones do you recommend?

Thanks tantejuut!

I did hear lots of good things about the FI-50 NCF but I don't really want to spend that much. I like your idea making a star quad out of a stripped NEP-3003, that was another cable I was considering.

As I believe matching the metals of the connector and the socket and since I was going to install the Furutech SWS R NCF wall socket, perhaps I will try the Schuko VIborg Rhodium but at the IEC end have a gold plated connector to give a little warmth. Have you tried the Viborg IECs ?

I like the Weiss DAC 202, most of the time it drives the power amps directly but something I insert a BAT VK40 preamp in the chain changing the tone totally. I have too much choice changing the character of the system, before the Weiss there is a Trinnov ST2-Hifi used in digital mode only.... anyway I diverted...

Btw thanks for the Puritan link, useful.

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.

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?
