i m sure there is different between powercord , i start playing av for 4 years , sometimes, i will think is it worth $1000 per cable , so if i have around at least 5 machine need to change , i need 5000 ,+ a power conditioner $1000 at least , how about if i take the $5000 to buy a higher model av amp or buy a second hand power amp, is the powercord makes the different worth $1000,or all the power cord can win a higher grade amp or a power amp ,i don't think so at some point , no offence , just wanna share my point n see what u guys think ???
