Which is more important - Interconnects or PCs?

All seriousness aside, I too think that it's difficult to organize a hierarchy of cables because it's so system and environment dependent.

If you have dirty AC, power cables might yield the best gains. If not, speaker cables or interconnects might do more. Also, it depends on what cables in the chain you're replacing with what, and then you have how each component might react to the cable.

So confusing.

Wow! Wow! Cool!

Real answer.

All the wire makes a difference, and once you start you'll end up replacing it all. A $5000 power cord isn't necessary, and some $5000 cords sell new for a fraction of that...and I mean liquidation prices.

You can get excellent results in a range of $200-$700 (I know it's wide). Look for used cabling, and take a serious look at the lesser known fabricators selling cords at auction. You can find some really good stuff there.
