AC Power cords, which components 1st...?


I've been lying in the background with regard to upgrading power cords and I'm now thinking that I might give it a try. I fully subscribe to the laws of diminishing returns with the exponential (if not worse) price curves of these products. Therefore, I'd be looking in the $50 - $250 dollar price range. I don't need long cables (3 - 4 ft should work) and that may help the price point. Pre-owned is fine with me as well.
Given that, which components first? power amps, pre-amp, source...? and, any thought on power cord given my predisposition?
Aloia power amps, Casanova pre/pro. Capitole MKII (soon, I hope).
Thanks

PS.....I say to start with the AC conditioner/regenerator, etc, if there is one, not so much for cleaning up the power, but to be sure your system is getting enough current. Anyway, the conditioner/regenerator will not have to work as hard if it has a good cord connecting it to the wall.
Check out the cables from Virtual Dynamics on Audiogon. $75 for a 6ft cryoed p/c. Just purchased one for myself and it's incredible. Spoke to Rick at VD and he said they are having a big sale to get some product recognition.
I would buy one and experiment. My experience has proven that it's not possible to predict the benifit to a single component within the system. I know from personal history the BMI Whale is a good fit for the Aloia, and I know the power snakes are very strong with the Casanova. Try the new Python, it is a very good cord. I use all NBS Statement but they will push your budget even used.
Definitely put a low-inductance cord directly to the wall outlet for your power amps first. Also, upgrade the outlet to a 15-amp with no steel in it - only brass. IF you want a really low-resistance connection, use the silver-plated Acme audio outlets.
Thanks all...a lot to consider.
When my dedicated 20 amp lines were installed several years ago I installed standard "hospital grade" outlets. That was before this new buzz/hype with regard to the audio grade outlets. Anyone know what the composition is in the hospital outlets?
