Neil,
You said that you now (recently) started to hear a difference in quality compared to the MiniDisc. It has been 2 years since the change. Think about it. If there was a change in quality due to the file format, you would have noticed the greatest difference immediately since the comparison to the old vs new would be fresh. Since you didn't know it (seemingly) at the time, it must be something other than the change to MP3 alone.
Hi David, I've noticed the change since I moved onto iPad playing the tracks.
My other player is a Cortex USB player I shall post picture of that Cortex 500 I think that's the model. I will post all my leads and iPad also the Cortex to. Thank you for your help, I notice the sound is thinner with the iPad and less louder, than the Cortex player which is USB front face loaded rack mounted player.
