Satori Shotgun or Hologram

I would use the money on a speaker upgrade before I would sink
that kind of money into such expensive cables. Just my opinion.

What do you hope to accomplish with these cables?

I ain't smacking B & W CDM7 nt's. But, I wouldn't mistake them for N803's. I am just saying, if it were *me* -- I would save the huge
cable money and I would put it into my speakers. I don't care what cables you use, those cables won't make CDM7's sound like N803's. I wouldn't get into top of the line cables at this point because I think that money is better spent somewhere else in the
system -- and without knowing the rest of the system -- if the CDM's are the speakers -- they are fine for a system at a certain price point, but putting top of the line cables on CDM7's -- IMO -- isn't in
line with building a system at that price point. So, the question remains -- what are you trying to accomplish? One sure way to get
better sound and better bang for your buck is to upgrade from those CDM7's. Will take you much further than putting AZ Satori's
on them. Should you bi-wire? Again -- IMO -- this is a relatively moot point. The CDM7's are a limited range speaker. They are not going to produce the lower octaves whether you bi-wire, bi-amp, or turn bi-sexual. So, the question remains -- what are you trying to accomplish with high end cables? I would suggest looking at your goals and then I think others can give better advice.
It would also help if you posted your system and not just your speakers.

Chevelle -- That's a nice system.

The CDM7's are nice speakers, but you can improve on them
with the money you're planning to spend on cables and a Sub.
Personally, I would much rather have full range speakers than
limited range speakers with a Sub. I mentioned B & W N803's
because they are higher up the line from the CDM7's and if you
like the B & W sound, you might check them out. The advantage
of a speaker like the N803 is that it is full range and coherent
from top to bottom. I would rather have a speaker with crossovers
designed by an expert than to try to match up a Speaker and Sub.
I think you'd be much happier with the sound and you'd see a much bigger upgrade than you would by adding high end cables
and a Sub. Certainly, before you buy a Sub, try to A/B your speakers with a Sub versus the N803's and see if you don't agree.

Another speaker you might want to check out is Sonus Faber Grand Piano Homes.

The Sonus Fabers are less expensive than B & W N803's. To me, the Sonus Fabers beat any of the B & W's until you get to the N803's and the N803's just barely nip them. But the Sonus Fabers are a big bang for the buck, IMO, and you can usually find them
for around $2,200 used on A'gon. That's far less than a new pair
of N803's. Plus, the Sonus Fabers are a lot more efficient and won't put nearly the strain on your amp as the B & W's. Try to get out and listen to the Sonus Fabers. Happy Holidays to you, too!

I would hold off on an AC Conditioner, but eventually you will want to do something about AC Conditioning if you keep upgrading. For now, a power strip with a surge protector is enough. That's my opinion.

Chevelle -- right now, if I were you, I would put my money into
better speakers, then better CD player, then better Amp. After you've made those upgrades -- on your next round of purchases,
I would look into a nice AC Conditioner. Take all the money you want to spend on Subwoofer, high end cables, AC Conditioner
and put it into your speakers and then CD player and then amp -- you'll get a much bigger improvement in sound than putting all those expensive accessories on your present system.
