Ajay,
I use Furutech IEC and male sockets for power cords of my amp and CDP (the Naka RX505 deck does not have a removable power cord). The particular model I use is Furutech FI-11G. They cost approx USD 50 each. So for each power cord, it's about USD 100. I use them with Audio Art power cords (designed by DH Labs, and made probably in Thailand). Both the cord and the connectors are available with ARN Systems Bangalore. The Oyaides as suggested by Prem are also very good, for similar models perhaps cost a bit more. The Wattgates are perhaps worse than these two in performance (based on my impression gathered from reading users' reactions worldwide). BTW the Furutechs go into international-type Crabtree sockets (easily available with Havels dealers) which sit in an extension box that I got made in a star configuration with Finolex cabling.
I am a physicist, and I never believed the last meter of the power supply to your electronics can have any significance. But I was clearly wrong. They made a HUGE difference, so much so that I had to reconfigure my set-up a bit, especially had to change CDP-to-amp cable, otherwise there was a bass boom. If you want me to summarize the effect, I'd say the signal to noise ratio increased noticeably, and as a result there was more clarity and transparency, more dynamics, more slam, and yes better and more bass.
I like also to add that good cables make perhaps some difference (but I do not have much experience in switching a lot of power cables), but what I felt was that the connectors really made a bigger difference.
I still wonder at times how is this true (PratimBayal who is now experimenting with similar power cords borrowed from myriad is also reporting exactly similar effects, that power cord has the same Furutech connectors as mine, but the cable is from Siltech). I feel perhaps with a DC main power supply, the effect would be insignificant, but with AC, current is flowing into the equipment as well as flowing out of it and perhaps the first meters (as opposed to calling them the last meters) are important. I would not blame the non-believers, because as I said I did not believe it myself.
BTW, I have a few questions related to earlier posts in this thread. I'll ask them whenever I have more time.
Regards.
