Eddie - The nearist richer sounds to me is in Sheffield, about an hours train ride away, why do you ask?
Hifi Newbie - I'll look into a new psu its just my current one cost over £80 so i am reluctent to replace it. I only live in one room but it is a large one so i can put the pc at one end and listen to my hifi at the other, hopefully this wont be too bad, i also have control over the speed of my fans, when put to there lowest rpm its not too bad, i just couldn't do anything demanding with the pc while listing to my music.
I think i'm going to go with a DAC over a cd player as i rarly listen to a full album all the way through any more. Is the CA dacmaigic the best one to go for? So i'll be able to hook the dac up over the optical out on my xonar and it will work fine?
