hi there, as the title says really - has anyone out there tried this?
I replaced the mains cable on my NEC HT1000 with both a special mains one from a forum member, and then a shielded cable with ferrite cores, and didn't see any difference to the picture with either cable. I now have the shielded cable on the pj, and the other cable on the HTPC which is my main source. I still can't see (or hear) any differences. YMMV of course.
Like Gary, I have tried different cables with various Sim2 models and not seen any difference in picture quality.
I think the reason for this is that projectors use switch mode power supplies which will run off a wide range of voltages and frequencies so they are not "fussy" compared to say the transformer/rectifier/capacitor psu in a power amp for example.
And of course it's the same scenario with PCs, ie. switch mode psus again.
ok, thats very interesting.
thanks for replying guys.
I have some Kimber PowerKords for my Denon amp and DVD player and the difference in sound and picture quality was amazing. Because of the improvement, I then bought a Mains Purifyer Block also from the same company which has six sockets.
I then used one of these sockets for my Sony 46" rear pro and found a real improvement in the picture, certainly reducing picture noise.
Slightly off forum but hope that helps.
I am still looking to move up to a DLP or D-ILA this year and I will certainly use another PowerKord or the PowerBlock with this.
I need a longer mains cable for my Domino anyway so would you all agree that there's no point in spending money on anything more than the most basic of cables.
I'm sure that companies like Sim2 would supply a super-duper mains cable if it could improve the image quality, but as they don't, you only have to ask yourself why.
They spend enough time and effort to develop their products for optimum image quality, and for the sake of a few pounds, they could easily supply a special mains cable, but they don't, so I would think a similar but longer cable of the same current carrying capacity should be fine.
Jeff - any ideas what Alan would say officialy on the matter regarding mains cables? It would be interesting to hear from manufacturers on the matter.
I will ask Alan next week unless he chips in here but I think I know what he is going to say
I did a little test some six months ago with different mains cables and power conditioners. I used two 300 Xtra's side by side fed with the same signal source, one was standard and the other had the conditioners and different power cables. Using test patterns relating to frequency response, resolution and colour I coulld not see any difference between the two units.
Having said that, using the same products on my audio systems at home did yeild improvement in sound quality, bass was tighter and and the overall sound appeared more transparent.

Thanks for the input Alan, much appreciated.
Yep, that does sound about right - power cables etc.. for the hi-fi/av and normal cables for pcs and projectors.
