Only you can say it's transparent. We don't know what you're hearing. You need to decide
I recently tried 96 AAC VBR, and it sounds surprisingly good. I can't ABX it :/ Apart from that particular Rammstein sample....If I convert them to 96 AAC VBR, would you say it would be transparent?
Everyone is climbing on the bandwagon of saying only the OP can judge his own level of transparency, but if other people are going to listen to his music on his player, then it is a fair concern whether it will sound ok to most people. You may not have noticed that there is a category on the forum for listening tests. Take a look there, and some of the larger participation ones are archived at: http://listening-tests.freetzi.com/
