Hey guys. I recently did an A/B comparison having read so much about how CD-Rs sound better than the original CDs.
I used dbpoweramp to burn all of them.
In every case (in my system, to my ears...) the original CD won.
I compared about six different major brands (Sony, Verbatim, Memorex...) and I did include Memorex black.
Of the brands compared, only Verbatim rose above the pack, coming very close to the original CD. I found that the rest gave up (too much) detail in exchange for warmth. Of the rest, Memorex black were one of the warmer - but certainly not the worst performer - that honor went to regular Memorex.
But there was honestly very little difference in the CD-Rs with the exception of the Verbatim. It was the Verbatim with the Light burning cover option.
I haven't heard any of the really high end CD-Rs.
