Installing Dedicated Power Lines -- Need Advice

In NYC vinyl jacketed cable is not up to code. The JPS Labs wire I selected
would have to be in a conduit. The electrician has already wired with armored BX cable but can still replace with the JPS. It’s a 70 foot run, so would cost $2100. The Synergistic Research PowerCell 8 UEF SE will be just a few hundred more than that, so I’m thinking (as Millercarbon suggested) I may get more bang for the buck spending the money on the conditioner. However, it’s not strictly a zero-sum equation here. This is a big renovation (all old panels and wires are being replaced as a matter of course) and I just got quoted about $2k for each dining room chair, so am feeling particularly justified in spending a bit more on something that tickles my ears rather than simply supporting my derrière.

All things being equal, is there a better bang for the buck spending $2100 on JPS labs in-wall cable or upgrading my power cables? The advisor I’ve been speaking to at the Cable Company has suggested
it’s more cost-effective to supply better power from the source (in-wall) than to correct it between the outlet and component through power cords. Would appreciate responses on this last question only from those who would spend ANY money on upgrading power in the first place. 

Electric is close to done and walls
will be closed up soon, so would appreciate responses!

dkidknow:
I seem to have heard differences in cabling, including power cords, and as I said, I have not heard conspicuous differences with dedicated lines. (Of course, lines not an easy change to meaningfully A/B).
So I hunch you'll hear more from the outlet than to the outlet.  FWIW, I think you'd hear more with the same dollars in things besides cabling -- for example, a well considered 2100$ upgrade to speakers.
(One exception might be if if your kit is on a heavily loaded circuit: I suspect one could hear the draw of a refrigerator cycling.)
All things considered, though: my advice is to do the AC.  My reason for this has to do with psychology unrelated to sound: now is the time to do it, since it will be an expensive hairball later, and if you stay in the hobby, you'll regret not doing it.  From the wall improvements can always be done the next time you are feeling spendy, but not the AC, at least for a sensible price.
So my vote is to do the AC, and sleep well, secure in the knowledge that you are doing everything right.  :)

Jdoris, that’s some pretty solid reasoning, although it’s scary to think these are the things we require to sleep well at night.

FYI I’m already stepping my speakers up several levels because my little Merlin monitors won’t be able to fill the 28’ x 20’ room they’re moving to. The Merlins are moving to a home theatre in the den with a sub to round them out. Still not sure exactly what I’m going with for the main rig, but have basically narrowed my focus to Bache 002AB or TriBeCa, Focal Kanta 2 or Devore Super 9.

Sorry to jump in at the tail end but you may want to consider running your equipment off a rechargeable battery. Here’s a link;

Well, maybe not a cure for insomnia!  But I never did regret doing my lines, and eliminating one potentially messy variable, even if there was not an audible 'wow'.  And the sticker price will seem muted, as part of a larger rehab.

On the speakers, huge fan of Devore -- John is a really nice guy, and it would be nicely fitting for you to buy local, from a builder who has NYC apts. in mind.
I have not heard the Super 9's but I much preferred the O/93 and 0/96 to the Nines -- more relaxed and musical I thought. If you are keeping the 22wpc amp, or are in any event committed to lower power tubes, I expect you'd welcome the higher efficiency of the 0s.
I came very close to getting the 93; for my money, they were quite competitive with the 96s at 75% of the cost.
