Hi Larry,
Great. One very important question, where does one buy Audiotop? I don't see them advertised anywhere. Do you buy direct? Do you have a contact number?
I'll also suggest, since you are doing comparisons on CDR's that you add one CDR to your test; pre-clean a disc with Shine Ola before you burn it.
We have a group of 4 to 5 guys that meet from time to time, just like Albert Porter's group. As soon as we can find out where to buy Audiotop, we'll share our conclusions as well. One CDR precleaned with Audiotop, one afterwards. One CDR precleaned with Shine Ola, one afterwards, and one that remains untouched.
If we wait a week or two, we can have BLER tests conducted by a friend that works at a large, well known software business that transfers sensitive data. He has benches filled with test equipment which test for things I'm not even aware of.
Best wishes,
Jack
