acknowledging the importance of good cabling and clean power... $5.7k might be out of balance in a $12k system. i would counsel first getting the best amp, speakers and source possible, then backfilling over time with expensive cables and power conditioning if needed.
in the interim, there are many great low cost cables that provide excellent results. also, diy cables are an option that can provide equal results at an even lower cost... in fact, many who could well afford otherwise choose diy with dueland wire - not because it is less expensive but because they prefer the sound. see this positive feedback review by jeff day.
if a/c power is an issue, something like the audioquest niagara 1200 for $1,000 msrp should be great in a $12k system.
