I personally will buy more storage if it meant improving sonics since it is so cheap, so moot point. Unless your worried about space on an iPod itself or other portable player. This is the very reason I like ALAC. Although in my trials I could not hear any difference between FLAC AND ALAC, if you can you're a better ear than me. Although I feel I heard better with WAV, could be in my head.
Anyway, I have no interest in worrying about compressing my audio files more on my home system, particularly where I have a TB of space.I worry about space-saving for music that travels, which is only worthy of headphones anyway.
Apple Lossless is as good if not better than all you swear are the better here in this thread, sorry to say. I am well versed on the subject as well, and I work very closely with this technology. Also in case you weren't aware, I have a USB DAC with a tubed output, so all my music is HDD based, all ALAC, with error correction, and it sounds better than the actual CD on a Meridian G08 CD player. Go figure...
