I've now built my PSU into a really cheap utilitarian steel case bought on eBay which matches the utilitarian look of the SC22, and I went for captive mains and HT leads so as to avoid cutting an IEC socket hole, and because I couldn't find an octal chassis socket that didn't 'worry' me. Plugged it in, the SC22 lit up and connected it between my phono stage and my power amps, and it sounds very nice indeed. I'm suspecting it may be light in the bass, but as things are connected at the moment I cannot use my subwoofer with the Quads so that may be why I'm thinking this. What I was expecting was for the SC22 to be a bit 'murky' but it's not at all. Very pleasantly surprised, and no hum whatsoever which is also a bonus.
