On a side topic.... do you have any/many music files you have at 256 kbps AAC that you play through the Lab 5s? If so, how do they hold up compared to lossless? I have a mixture of lossless AIFFs and AACs and don't want to try and get all AAC files as lossless, unless they are poles apart.
Hey Justin
After reading about Soundproofs comments about lossless above, I decided to rip a few CDs in lossless for my iPhone. I can't comment on the Beolab 5s but I can hear the different between 320Kbs on my A8 earphones and lossless on my iPhone. With the beolab 4000s it is very clear the difference. I think the Beolab 5s will clearly show a marked improvement. I just spent the last few days re-ripped all my CDs from 320kbps to lossless (around 900-1000kbps).
