Bob, measureing dynamic range at home is fraught with difficulties. One tends to end up measuring signal to noise ratio even when using a scope. An interesting working of the maths can be found at http://www.st-andrews.ac.uk/~www_pa/Scots_Guide/iandm/part12/page2.html , as the author quite rightly points out, the results are the theoretical limits of the media and practical applications will yeild much lower actual dynamic range in both media. He clearly shows that the limit on lp replay is about 110db as opposed to 96db in redbook compact disc replay. Interestingly, this coincides with my subjective evaluations. But don't get me wrong; the compact disc has much to recommend it, both technically and aurally.
How do you get past the pops and hiss of LPs?
I have recently got out my dad's old Thorens TT (TD 150 MKII) and listened to some of his old classical LP's. I think that it is a warmer sound than CD but I can't get passed all the noise. I asked my Dad and he said it always sounded that way. Am I doing something wrong? Do you just ignore the hiss and pops? Thanks in advance.
