Upgrading power cord.. proven upgrade? or crap?
The right way to do lightning and surge protection is with a surge arrestor at your power service panel.  Home Depot has panel-mounted arrestors for ~$60, and external (if you don't have room in the box) for ~$110.  Protects every electronic devic... 
Doubling a Set of Speaker Cables
I had my mind all but made up that there would be no difference, but I was wrong.  Anyone wondering, try it!  :-)

Doubling a Set of Speaker Cables
Doubling up on the wire from amp to speaker made a huge improvement on my system.  Perhaps, because the speakers are 4 ohm, but it sounded dramatically better.  I was quite certain I wouldn't hear anything, but it was the opposite.  TRY IT.  :-)  ...

Upgrading power cord.. proven upgrade? or crap?
Completely agree with stringreen. Powercords are more noticeable than interconnect or speaker cable. They make profound differences too, but the powercords are HUGE. Try one of the dozen from Purist Audio Design. Extremely effective. 
Looking for SACD player............
Have you tried the Oppo BDP-105D?  It ought to cost WAY more than it does.  A phenomenal SACD player, the balanced outputs sound wonderful.  Having a hard time finding anything better under $10k.  That player is amazing. 
Which Processor?
The Foundation stomps the S-1200, I know as I've compared both thoroughly.  The Foundation is an EXCELLENT sounding preamp and processor.

Best preamplifier, amplifier for B&W 800 Diamond
The Krell Solo 575 monoblocks ran my 801D better than any other amplifier I've heard.  They had great speed, detail, a nice large/deep soundstage, and punchy (but tuneful also) bass.  Loads of power too.  They outperformed my massive EV900e monos,...
