Yeah, APE does have a pretty good compression ratio, but the highest levels take the longer time to decompress, unlike FLAC, which stays at the same speed for all the levels. Only TAK can better that.
Renegade, blame the loudness race. Higher sampling rate doesn't help anybody (human maximum level perception is around 20 KHz, but due to the Nyquist theorem, it's ideal to have that ratio doubled, that's why the 44.1 Khz), except rabid audiophiles and whales ;D. Actually, the loudness race problem is even being featured on the mass media these days, so I hope those producers take notice, and we don't get disasters as Californication (the album, not the TV series). It pays off during recording and for master copies, though.
