Audiooracle:
Anyway there is more to the Memory Player than what you surmise: for one: the software is quite different than EAC and a ram disc is still ram setup as a virtual space on the hard drive, which means you will still have timing errors.
Actually, a ramdisk is the opposite of what you describe. A ramdisk is a virtual hard drive IN RAM. It's a chunk of RAM that appears as a hard disk to the computer. They're fast, because they're RAM and there's no disk access (and no timing errors). And since the ramdisk RAM is reserved and contiguous, no other data is mixed in with the music data.
I believe MTU has been using ramdisks to play songs since the late 1970s. And I believe they offered Apple II software/hardware that allowed manipulation and playback of songs from ramdisks in the early 1980s.
I'm not trying to knock the MP. If it sounds great, then great. It's definitely a step in the right direction for audiophiles who don't want to mess with PCs.
