My system NAC 272 250 DR naca5 speaker wire and focal 1028be. Firstly due to wifely complaints my system is not best position however the amp makes a really loud hmm to the point you actually can not sit next to it I would guess about 45dB. It has to be the power supply as this is the second amp and both are the same.
However my question is, would a power conditioner help and does the russ andrews justify the cost over a £40 one. I have read a few articles however they all seem quite old the newest being from Hugo (2010) . So I'm wondering if any one has tried any recently. I also note that a direct power supply to the mains is best however the consumer unit is on the other side of the house.
