Well finally I've managed to get to my PC, The Black Memorex CD-R's turned up a few days ago, and I'm pleased to report that they seem to have a superior sound in comparsion to my Standard TDK Media, Both CD-R are infact manufactured by CMC using the same dye.
I noticeted that Bass and Treble seemed Sweeter, and less distorted,and a bigger soundsage.If I had to be honest, it sounded like a lathed CD-R that was working only at 50%, so it would seem that Black Surface is improving things at my end.
My next step, Black Lathed CD!
