Thanks for the words Lkdog. As far as the power cord. I am not sure I'm qualified to make a great judgement. I simply was replacing a stock cord. In terms of the comparison to the stock...the RS Audio is amazing. The most obvious difference is the lowering of "static" in the high range. I didn't do any A/B comparison, but after the break-in of the cord, I did feel there was more bass and a more mellow sound (perhaps because of the loss of static).
Now the interconnect I compared a bit back and forth to the Sonic Horizon (daybreak). Now I really enjoy the Sonic Horizon, but felt there was something missing, especially since the daybreak is on the lower end. I updgraded to the RS Audio Mark II and after many days of break-in, I can actually say I hear some difference, if even a greater clarity in soundstage on my system. The family even tells me it sounds better...so maybe that is your answer.
