Dream system - but no aftermarket power cords

Hi,
after tweaking many other aspects of my system, I have had to deal with substantial noise from my Piega C10Ltd speakers recently.
This has led me to order a Synergistic Research Tesla PowerCell 10SE which should arrive later this week.

So, after getting into the "power" game and reading up on some PC reviews, I am still lost with regards to the baseline strategy to upgrade the stock cables on all components.
Here's my current setup for my 2 channel speaker system:
[Squeezebox Transporter] - [McIntosh MDA 1000] - [Piega P1 Mk ii active subwoofer (RCA loop-through and cut-off at 75Hz)] - [Marantz MA9-S2 mono amps (2x)] - [Piega C10Ltd]
All active components will be powered through the PowerCell.

So here are my preliminary thoughts, please feel free to comment:

1. Order of upgrades
1.1 Frequently, it's recommended to "upgrade the transport" first. In my case, would that be the Transporter (I guess? Or upgrade last because it's only feeding the DAC?) or the MDA-1000 (which is serving double duty as DAC and preamp, so could I double the impact from a better PC??)
1.2 The Marantz amps with their massive capacitors ought to be the least power sensitive piece of gear (??? not sure about that), so it would make sense to upgrade them last?

Of course the whole question about order of upgrades is related to
2. good-better-best strategy
2.1 what's considered a solid baseline for a highend system like mine, I don't have the money for (new) Valhalla everywhere (I need 5 PCs total)?
2.2 back to order of upgrades: looking at the individual pieces of equipment specifically, where do I get to the 95% point of diminishing returns? e.g. Synergistic apparently recommend Tesla T2 on sources and T3 on (pre)amps, is there a reasonable "segmentation" strategy?
2.3 how high should I value system synergies, specifically considering the fact that I will use a PowerCell; in other words, are there unwanted side effects from other cords (e.g. LossLess) trying to filter out stuff that the PowerCell has already taken care off and leading to a "lifeless" sound?

3. Looking at the list of components above, any recommendation about what you have found to work well with any one of the components listed above would be appreciated (e.g. Jerry Seigel recommended PS Audio PW 10 for the Marantz amps, I am reluctant to go there based on my general preference to avoid too much shielding)

Any help/suggestions much appreciated (I promise to report back my findings after trying out some of your recommendations in return!)
Thanks!
