i get a loud back whitenoise at 11 o clock or louder volume specially in betwing song and song and in some jazz recordings when there is silence of rest of music and you hear only bassist solo i called the dealer he told me to put of a switch and put on or try original cable i still have these noise.
will getting a better power cable reduce the noise my power cable is a Audioquest nrg from some years back.
what cables are great for these amp these dealer carries power cables from audioquest,chord company,in akustik and isotek i woud prefer to buy from there like i can pay in diferent rates .
I don’t think the problem is with your cable(s). What speakers do you have? Are they super efficient? Is the noise just normal amplifier hiss or is it something else?
have headphones i tryed also 2 other headphones of a friend with all it happened yes it,s a amplifier hiss just like you leave a guitar amp open at very hi.
11 oclock! 
Not surprised there’s some hiss.

As sktn77a said most likely it is not power cable, but power cable upgrade will improve 5si.

Jeeez !!! … 11’oclock, you cannot be serious.
What in room dB does that give?
If you haven’t already got one, get one of the smartphone or tablet sound dB meters & check.
70 dBA and lower is considered safe with no time duration.
85 dBA and above will damage your hearing over time.
Lots of info on this can be found on www
