Welcome!
You might want to check out the review done by kiwi_1282001 on the P vs C power cords in this thread - he did comment on the A power cord too. Other users that I have spoken too have suggested that the C is a more effective upgrade than the A power cord.
Ansuz (my dealer and other users too) would generally say that the power cord between the wall and the D8 is the most important link, the foundation, so to speak. So, P or C would be good there.
It also appears that longer lengths of the power cable sound better, with some hard core users that I know using power cords of up to 4m (at the D and DTC level!) This is what my dealer says too. I used to think that it all was, to put it politely, sales talk, until I compared the 2m vs 3m X power cord. Having said that, the 2m P power cord is better than 3m X power cord still.
On the USB cable, I have tried the A USB cable but was not that impressed by it. Others have recommended the D USB cable as being the best but that is not an amount that I am prepared to pay at the moment.
